4 CO Modular System Overview SYSTEM INTRODUCTION 4 The CO Building Drainage Modular 125 stainless steel linear drainage system is a further development of the highly successful Modular Channel system. Taking full advantage of the significant investment in state-of-the-art manufacturing plant, CO Building Drainage now can offer an improved performance, fully flexible stainless steel drainage system suitable for most applications off the shelf. Modular 125 offers the first choice for performance and flexibility. Significant improvements include: 4 Fully tested and classified to BS EN 1433 Drainage channels for vehicular and pedestrian areas for enhanced operational confidence. 4 Vee-bottomed profiled channel for enhanced flow efficiency at low flow rates. 4 Extended range of constant depth and sloping invert channels and accessories. 4 Unique optional grating security locks available without extended delivery time penalty. 4 Lightweight channel sections minimise the risk to construction employees during the installation phase. 4 Wide variety of invert depths and channel falls to suit most applications. Manufactured in corrosion resistant 304 grade austenitic stainless steel that is fully pickle passivated to remove embedded iron and chromium-depleted weld-zones, outstanding performance and longevity is assured. For particularly chemically aggressive applications, Modular 125 is available in 316 grade stainless steel to special order. The enhanced corrosion resistance and extreme durability of stainless steels make the material suitable for many applications demanding a reliable, long-life performance. One key attribute of stainless steel is often overlooked in that the raw material is manufactured from at least 70% of recycled materials, therefore significantly contributing to a sustainable environment. dditionally, stainless steel can be 100% recycled if the products are ever removed or at the end of its working life. 4 Level invert 4 Continuous fall 4 Combined fall 4 Vee channel profile 4 Wide grating choice 4 System fully BS EN 1433 compliant

12 CO Modular System Overview SPECIFICTION ND ORDERING PROCEDURE Ordering the Modular channel system With the wide range of products available off-theshelf, specifying and ordering the Modular 125 system could not be easier. The following procedure addresses product selection and ensures that all aspects of the system are covered. Should you wish, CO Building Drainage can provide a take-off service based on your plan details. Modular system customisation Sometimes it is necessary to shorten a channel and grating, or provide an outlet or inlet beyond those positions available in our standard product range, all of which is easily accommodated in our flexible manufacturing facilities. Contact the CO Building Drainage Helpline on for further details and advice. Step 1 Load considerations 15 Page Description Helpful Hints Select appropriate grating Load Class to BS EN 1433 for the particular application. For Load Class C250, channel edge PVC infill will be supplied as standard. lways allow for the highest loading. Particularly for industrial applications where pallet trucks and fork lift trucks may access the system, assess vehicle wheel loads as these can vary depending on the vehicle. Consider future use where possible. General Considerations Vehicles with solid tyres impart greater stress on gratings compared to pneumatic tyres, so care needed. Do not use 'slip resistant' gratings in areas where turning vehicles are likely to damage the grating. 12 Step 2 Outline plan 6-7 Produce a plan of the proposed installation, identifying outlet points and invert depths at that point. CO offer a free, no obligation hydraulic calculation service which can optimise channel depths for a given capacity requirement. Built-in fall (sloping invert) channels provide a degree of self-cleansing and should be used where possible. However, level invert or flat channels can function hydraulically where construction depth is restricted. Step 3 Selecting an outlet Select an outlet with an appropriate flow rate which meets any invert restrictions. Horizontal outlets offer shallower outlet points but are not as efficient hydraulically. s an outlet will be at the lowest part of the system, select the deepest possible invert to allow for falls in channels connected to it. Consider both maintenance facilities and aesthetic considerations.

13 CO Modular System Overview SPECIFICTION ND ORDERING PROCEDURE CONTINUED Choosing an Outlet Page Description Maintenance esthetics Modular Outlet option 1. Spigot The Ø110mm outlet spigot can be supplied with or without a foul air trap. If no foul air trap is used a sediment basket can be installed. If a foul air trap is used a debris sieve can be fitted. n optional sediment basket or debris sieve provides some degree of maintenance. Complete cleaning will require removal of the foul air trap. Jetting / rodding via the removal of the foul air trap. Spigot outlets are not visually intrusive and can be located by visual inspection along a channel run. Modular Outlet option 2. Leisure discreet gully 19 The Ø110mm outlet leisure discreet system provides greater flow rates than a spigot outlet. Flow rate is optimised in the 125mm deep gully. Optional sediment basket requires periodic removal and cleaning. Jetting / rodding via the removal of the foul air trap. Visually non-intrusive and can be located by visual inspection along a channel run. Modular Outlet option 3. Gully systems One or two-way gully top options with a Ø110mm outlet, providing greater hydraulic capacity overall. Hydraulic capacity maximised in vertical orientation. Maintenance is effected through an optional sediment basket or sieve with a foul air trap supplied as standard. Gully bodies have rounded bowls to minimise silt build up. The gully top is wider than the channel and is therefore identifiable within a channel run. Gully top grating options do not include Slotted, Plastic, Composite, Quadrato or Slotted Intercept grating styles which are available in the Modular channel grating range. 13

14 CO Modular System Overview SPECIFICTION ND ORDERING PROCEDURE CONTINUED Page Guide Helpful hints Step 4 dding channels Start at the outlet position and work back adding channels as appropriate. Where combined falls or sloping falls are required, ensure there is a logical fall to the outlet where the deepest channel sections are positioned. Consider the depths available in corners and branch units which, if a built in fall is required, should be a shallower invert than the outlet. General considerations Increased run lengths can be effected by introducing level channels within a run of built in fall channels. Using longer length channels saves cost, minimises joints and reduces installation time. Shortening built-in fall channels is possible only at the start of a run. To adjust a built-in fall mid-run, it is necessary to introduce a level invert channel. 14 Step 5 End plates 26 Terminate the system with end plates corresponding to the channel depth at that location. N/ N/ Step 6 Channel edge accessories Select an edge detail appropriate for the Load Class and flooring finish. PVC infill provides a low cost option for improving overall channel durability, particularly in trafficked areas. Vinyl / flexible sheet flooring can be seamlessly welded to CO Building Drainage Vinyl Seal. Step 7 Gratings Select correct Load Class for the application. Do not use slip resistant gratings where vehicles are likely to turn on the grate. Consider grating availability for both channel and gully. Security lockings can be added at extra cost to all gratings. dditional lead time may be required. For bare foot areas consider Heelsafe, Quadrato, Intercept or plastic grating styles.

15 CO Modular Technical Data and ccessories LOD CLSS Unfortunately, for historical, application variances and material specific applications, there is not one standard with universal Load Class criteria that covers all building products and applications - which can be quite confusing for the specifier. CO Building Drainage consciously decided to develop the Modular 125 channel system to conform to appropriate European standards in order to provide the specifier with confidence to specify products that will offer known reliable performance criteria. The Modular channel system has been tested in accordance with BS EN and complementary gully systems to BS EN Because the general nature of the two types of product is different for many applications, the Load Class criteria described in both standards are different. However, in the table below a practical approximate comparison is provided to aid the specifier select products appropriate to the application.

34 CO Modular Installation GULLY ND CHNNEL INSTLLTION Basic Instructions details may vary depending upon application Step 1 Base Preparation Step 4 Pour Concrete Prepare base with 100mm compacted Type 1 fill. Sept 2 Gully Positioning Pour concrete slab and leave for 24 hours before removing shuttering. Step 4 (Continued) 34 Position gully bodies and measure for shuttering and oversite concrete level. Step 3 Construct Shutters Keep pipework clear of loose materials. Step 5 Re-Position Gully Construct shutters, position and mark concrete level. Leaving the shutters long allows easy removal after concrete pour. Position gully(s) and check levels. Keep loose materials clear of gully.

35 CO Modular Installation GULLY ND CHNNEL INSTLLTION Step 6 Backfill Gullies of the channel to allow access to levelling feet, fixing ties and flange plates. Prior to bedding and haunching, check joints and traps for water tightness. Backfill gullies with concrete and float to flange level. Step 7 DPM Fit DPM and clamp in flange as appropriate. Step 8 Channel ssembly Step 8 Form Levelling Screed Shuttering Taking into account finished floor materials and thickness (sharp sand, paviors, tiles, vinyl etc) construct shuttering for the levelling screed. Pour screed and remove shuttering. Weigh the channels down when back filling the trench to prevent the channels from lifting or floating. Fully extend and twist channel fixing ties to provide a good anchorage. Pour suitable cement or resin mortar around the channel. The mortar should be of a type and consistency to ensure there can be a good compaction of this material both under the channel base and particularly under the channel edge. The bed and surround must have sufficient strength to support the channel in service. For light and medium duty applications up to Load Class C250, a suitable mortar of Strength Class C30/37 to BS EN with a maximum aggregate size of 10mm should be used. Where it is not possible to provide the depth of surround as prescribed in Step 2, a suitable mortar of Strength Class at least C35/45 to BS EN with a maximum aggregate size of 10mm may be used to support the channel 35 Loose assemble gullies, channel sections and joint gaskets. Leave spacer bars intact until channel has been completely installed. Loose assemble gullies, channel section and joint gaskets in drainage run ensuring compatibility of adjacent channels, position and level before final tightening of all joints. For Load Class C250 applications, allow 200mm either side and under the channel for concrete backfill support, where this is not possible, seek engineering advice. For Load Class 15 and B125 applications, allow for a minimum of 30mm of bedding material and approximately mm either side following engineering advice. Step 8 (continued) Remove immediately from the inside surfaces of the channel (or gully) any mortar or concrete spillage. For channels with vinyl edge detail, refer to pages

Set paviors 3mm maximum above channel edge. Complete paviors on compacted sharp sand bed. Step 9b Tile Finish Step 10 Sealing mastic sealant should be provided between the edge of the channel and floor typically 8 10mm wide and 10 15mm deep. In some cases it may be necessary to apply a suitable primer to the stainless steel before applying the sealant. The sealant manufacturers advice should be sought for each individual application. Step 11 Grating Installation Spacing bars with the channel are provided to give stiffness and rigidity during manufacture, site handling and installation. They also prevent closure of the grating aperture during the concreting phase of installation. 36 Prepare haunching on screed base working mix under channel and gully top flange. Lay levelling screed and lay tiles in cement bedding. Step 9c Flexible Sheet Finish Fit the CO Vinyl Seal rigid extrusion and flexible seal system to channel and gully edge as described on pages Prepare haunching These bars should be left in position until immediately before the gratings are inserted in place. The spacer bars may be removed by striking them with a sharp horizontal blow with a mallet. Step 12 Cleaning Remove all protective tape from the channel edge and clean the surface with a solvent if necessary to remove any adhesive residue. Wash and clean the channel, empty the silt basket and refit the gratings. Cutting and Welding On-site It is not easy to work with stainless steel on site, as the material is particularly hard and special cutting equipment is needed. Similarly if stainless steel is welded on site then care should be taken to ensure that all welded surfaces are properly finished either by hand, or with an acid finishing. It may not be possible to achieve a uniform surface appearance or guarantee full passivation of the weld in these circumstances. Hence finishing under factory conditions will be far superior in this respect.

37 CO Modular Installation CO BUILDING DRINGE VINYL SEL Sealing Vinyl Sheet Flooring to Drainage Channels and Gullies Vinyl sheet is a common flooring finish in many of the areas where stainless steel drainage channels and gullies are required. Previously the standard method of jointing the two was by a mechanical clamping system. lthough functional, this mechanical clamping mechanism can be cumbersome to fit and increase the potential areas for bacterial growth. In order to overcome the frequently encountered problems of achieving watertight and bacteria free seals, CO have developed the CO Building Drainage Vinyl Seal a unique solution that will enable quick, easy and economical installation. CO Building Drainage Vinyl Seal provides a completely watertight and bacteria free seal. This method of sealing requires no additional tools or skills other than those required for the professional fitting of vinyl sheet flooring, making the installation quick, easy and economical. The seal is significantly more cost effective than the traditional mechanical type and is designed to fit CO Building Drainage stainless steel drainage channels. Channel Edge Flexible seal Heat welded joint Vinyl sheet flooring (2-4mm thick) Floor adhesive Step 1 Remove channel protective tape prior to fixing extrusion. Step 2 Cut grey rigid extrusion to suit ensuring any mitres are cut accurately otherwise pressure points may appear in the finished fioor in use. Step 3 Using Sheet Plier Grip Wrench supplied, clip the vinyl seal rigid extrusion to underside of channel Step 4 Where there are joint plates in the channel run cut a notch out of the rigid extrusion as shown to enable the extrusion to be clipped to the underside of the channel. Step 5 Here you can see the rigid extrusion cut to suit and fitted prior to the fitting of the black flexible seal. 37 (Patent applied for) Rigid seal extrusion Step 6 Insert the black flexible seal as shown, making sure that the curved concave section of the seal faces TOWRDS the channel edge and that the groove in the flexible seal engages with the notch on the rigid extrusion. (It may help to lubricate the flexible seal when inserting using a water soluble soapy solution).

38 CO Modular Installation CO BUILDING DRINGE VINYL SEL 38 Step 7 Using the Sheet Plier Grip Wrench, proceed along the channel inserting the flexible seal. Step 8 s can be seen when fitting around a corner, the flexible seal may be kept in one piece to minimise joints. Step 9 Here you can see the rigid extrusion and flexible seal fitted prior to screeding / back filling. Step 10 Install the channel into the ground ensuring the flooring screed is flush to the top edge of the rigid extrusion. Protect the channel & seal assembly from splashes of concrete or screed. Step 11 Depending on the installation, additional suitable fixings may be required to secure the rigid extrusion to the floor substrate. If this should be required, separately drill and countersink the rigid extrusion making sure all the fixings are finished flush with the top of the extrusion. Step 12 Grout any voids at connecting PVC joints and mitred corners straight joints or fixings to ensure a continuous fully supported finish. Step 13 Prior to laying the vinyl sheet flooring, peel the protective film from the rigid extrusion (a knife may be required to cut the film adjacent to the flexible seal) and ensure all surfaces are clean and dry. Step 14 When preparing the vinyl sheet material and floor surface, apply a compatible adhesive also to the top surface of the rigid extrusion e.g. ltrofix 19 two part water resistant eurethane adhesive. taking care not to apply adhesive to the flexible seal. This is to ensure the vinyl sheet floor is reliably anchored over its full area. Step 15 Lay the sheet flooring against the flexible seal edge and prepare the welded joint between the flexible seal and vinyl sheet flooring as normal by scoring the sheet/seal joint to approximately half the depth of the sheet flooring thickness. Either in-colour or black welding filler rod may be used to weld the joint. Remove surplus weld material from the joint using a spatula when the welded joint has cooled.

39 CO Modular Installation CRE ND MINTENNCE lthough robust, all grades of stainless steel will stain and discolour due to surface deposits and, as such, can never be accepted as completely maintenance free. In order to achieve maximum corrosion resistance, the surface of the stainless steel must be kept clean. Provided the grade of stainless steel and the surface finish are correctly selected, and cleaning schedules carried out on a regular basis, excellent performance and long service life are assured. Factors ffecting Maintenance Surface contamination and the formation of deposits must be prevented in order to maintain a durable and hygienic surface. These deposits may be minute particles of iron or rust from other sources used on the building of new premises and not removed until after the stainless steel drainage products have been installed. Wire brushes and wire wool must not be used to remove marks and cement spillages as this will only serve to introduce iron impurities to the material surface. Care must also be taken when storing, erecting or cutting carbon steel near to stainless steel. Industrial and even naturally occurring atmospheric conditions can produce deposits which can be equally corrosive, e.g. salt deposits from marine conditions. The working environment can offer more aggressive conditions, for example the high humidity found in swimming pools increases the speed of discolouration and therefore requires maintenance on a more frequent basis. Modern processes use many cleaners, sterilisers and bleaches for hygienic purposes. ll these proprietary solutions, when used in accordance with makers instructions are safe, but if used incorrectly (e.g.warm or concentrated) can cause discolouration and corrosion on the surface of any quality of stainless steel. Strong acid solutions are sometimes used to clean masonry and tiling of buildings but they should never be permitted to come into contact with metals, including stainless steel. If this should happen the acid solution must be removed immediately by copious application of water. Maintenance Programme With care taken during fabrication and installation, cleaning before handing over to the client should present no special problems, although more attention may be required if the installation period has been prolonged. Where surface contamination is suspected, immediate attention to cleaning after site fixing will encourage a trouble free product. Food and beverage handling, pharmaceutical and chemical industry applications require extremely high levels of cleanliness applicable to each industry. dvice is often sought concerning the frequency of cleaning stainless steel and the answer is quite simple: clean the metal when it is dirty in order to restore its original appearance. This may vary from once to four times a year for external applications or it may be once a day for an item in hygienic or aggressive situations. Frequency and cost of cleaning is lower with stainless steel than with many other materials, and will often outweigh the initial higher cost of this superior product. 39

41 CO Modular Stainless Steel FMILIES Stainless steel is the name given to a wide range of steels which have the characteristics of greatly enhanced corrosion resistance over conventional mild and low alloy steels. The enhanced corrosion resistance of stainless steel essentially comes from the addition of at least 11% chromium, however most stainless steels commonly used contain around 18% chromium. Other significant alloying elements include nickel and for superior corrosion resistant properties, molybdenum. For CO Building Drainage applications, the principal properties of stainless steel may be summarised as follows: 4 Durable and corrosion resistant in highly aggressive environments. 4 Hygienic, easily cleaned surfaces. 4 esthetically attractive surface finish. 4 Good forming and fabrication characteristics. 4 Excellent strength and resistance to oxidisation at high temperatures. ll of which make stainless steel an obvious first choice material for demanding applications. Stainless Steel Families Stainless steel is used across a wide spectrum of engineering applications and this has led to the development of the vast range of different types of stainless steels that are now available. There are four main grades of stainless steel: ustenitic Stainless Steels This group of stainless steels is the most widely used and encompasses the generic 304 and 316 grades of material. These materials are used in the CO Building Drainage manufacturing process and are ideal for applications including food processing, leisure, dairy, brewing, pharmaceutical, chemical and petrochemical industries. 304 grade stainless steels contain around 18% chromium and 10% nickel and provides excellent corrosion resistance. For applications where superior corrosion resistance properties are required under extreme conditions particularly where chlorides are involved, 316 grade stainless steels are used and contain around 17% chromium, 12% nickel and 2.2% molybdenum. Unlike all other grades of stainless steels, austenitic grades are non-magnetic and as a consequence magnetic particles are not attracted to the system surfaces which otherwise would encourage both contamination and corrosion. 41 Ferritic Stainless Steels Ferritic stainless steels have inferior corrosion resistance properties compared to austenitic 304 and 316 grades and are used in less demanding applications such as domestic appliance and motor car trim.this grade of stainless steel is slightly more brittle when compared to austenitic grades. Ferritic steels contain between 11.5% and 16.5% chromium and less than 0.5% nickel. This group of steels are magnetic and will attract particulates which can cause contamination problems. Ferritic steels are not suitable for drainage products.

42 CO Modular Stainless Steel FMILIES ND CORROSION RESISTNCE 42 Martensitic Stainless Steels Martensitic steels are magnetic and have the highest strength of the groups of stainless steels, however they also have the poorest corrosion resistance. They can be hardened by heat treatment and generally find their main application in cutlery manufacture. Martensitic steels contain around 12.5% chromium and contain a relatively high carbon content of 0.3% (austenitic and ferritic steels contain around 0.02% and 0.04% carbon respectively). Martensitic steels poor corrosion resistance make them unsuitable for drainage applications. Duplex Stainless Steels Duplex stainless steels have an effective austenitic/ferritic structure and are characterised by good corrosion resistance, high strength and in particular, good resistance to stress corrosion cracking. Duplex steels contain around 22% chromium, 5.5% nickel, 3% molybdenum and 0.02% carbon. This group of steels are magnetic and will attract particulates which can cause contamination problems and therefore are unsuitable for drainage applications. Stainless Steel Corrosion Resistance The single most important property of stainless steels and the reason for their existence and widespread use, is their natural corrosion resistance. In spite of their name, stainless steels can both stain and corrode if used incorrectly. The reason for the good corrosion properties is due to the formation of a very thin, invisible oxide film that forms on the surface of the material in oxidising environments such as the atmosphere and water. This film is a chromium-rich oxide which protects the steel from attack in aggressive environments. s chromium is added to a steel, a rapid reduction in the corrosion rate is observed because of this protective film. In order to obtain a compact and continuous passive film, a chromium content of at least 11% is required. Passivity increases fairly rapidly with increasing chromium content up to about 17% chromium. The most important alloying element is therefore chromium, but a number of other elements including nickel, molybdenum and nitrogen also contribute to the corrosion resistance properties of stainless steels. Other alloying elements may also be added to enhance the corrosion resistance in particular environments. Stainless steels must oxidise in order to form the passive, chromium-rich oxide film. Stainless steels have a very strong tendency to passivate and only a small amount of oxidising agents are needed for passivation - air and water are sufficient to passivate stainless steels and indeed, this oxide film is spontaneously regenerated when exposed to oxygen. n important factor to note is that the passive film is self-healing, so when the material is cut or machined or, should chemical or mechanical damage occur, the passive film will heal or re-passivate in oxidising environments - unlike a painted finish on mild steel. Selection of the correct grade of material for each application is an important factor in the design process. It is important to note that even 316 grades of stainless steel are not immune to all kinds of chemical attack; use with reducing solutions such as hydrochloric and sulphuric acids particularly when in concentrated and/or hot form, requires careful consideration. See corrosion resistance chart on pages 45 and 46.

43 CO Modular Stainless Steel FINISHING PROCESSES Stainless Steel Finishing Processes stainless steel finish should appear clean, smooth and faultless. This is obvious when the steel is used for such purposes demanding stringent hygiene or decorative trim applications, but a fine surface finish is also crucial in respect to its corrosion resistant properties. The corrosion resistance properties of stainless steel are achieved by the spontaneous formation of a very thin chromium-rich oxide layer over the surface of the material. Unfortunately, surface defects and imperfections introduced during the manufacturing process may drastically disturb the self healing process of the passive layer and subsequently reduce the corrosion resistance of the material. In the manufacturing process it is the welding that creates the greatest challenge to corrosion resistance. ll CO Building Drainage products are subjected to specialised treatment to ensure the material retains the maximum resistance to corrosion. Pickle Passivation Plant Untreated Stainless Steel The blue oxide film has substantially reduced corrosion resistance. fter welding stainless steel, a bluish high temperature oxide film can be seen which has substantially inferior corrosion protection properties compared to the original passive layer. Immediately beneath this blue oxide film is a thin layer of chromium depleted metal which makes the metal surface susceptible to corrosion. Post weld treatment is, therefore, very important to restore the corrosion protection properties and is effectively achieved by removing the blue high temperature oxide film and chromium depleted layer to restore the surface of the material. This cleaning is essentially a controlled corrosion process using chemicals, this will restore not only its original corrosion resistance performance but also the high quality aesthetics. The chemical processing methods used in the CO Building Drainage process are summarised as follows: 43 CO resources include the largest pickle passivation plant in Europe

44 CO Modular Stainless Steel FINISHING PROCESSES Pickle Passivation The standard CO Building Drainage manufacturing process uses the pickle passivation chemical finishing process to restore the products to their full optimum corrosion resistant state without damaging the surface finish. This is considered the best method for cleaning welded joints. Electropolishing Electropolishing is ideal for producing a uniform, highly reflective lustre with an extremely smooth finish even on the most complex product contours. This is a well proven method of polishing and is achieved by an electro-chemical process which is essentially the reverse of electroplating. Pickle passivation is a two-phase process. 44 Pickle Passivation Process. Pickle Passivation restores corrosion resistance properties fully. Pickling removes both the bluish high temperature oxide film and the chromium depleted layer and is achieved by placing the components in a pickling bath containing a mixture of nitric acid and hydrofluoric acid. The second phase is passivation and in many ways is similar to the pickling process. For this process the components are placed in a bath containing nitric acid only. This treatment strengthens the passive layer and also removes any iron impurities that may have become embedded in the surface of the stainless steel during the manufacturing process. This treatment is important where mechanical cleaning of the components has taken place with the use of wire brushes, grinding wheels and files where iron particles from other materials may contaminate the stainless steel surface. Electropolishing. Electropolishing further enhances surface smoothness and provides a brighter surface appearance. The components are immersed in a bath of electrolyte containing phosphoric acid where the components become the anode of a direct current electrical circuit. The process is characterised by the selective attack on the surface of the components whereby upstanding roughnesses are preferentially dissolved and will yield a progressively smoother, brighter surface. For pharmaceutical and food processing industries, bacterial resistance is considerably improved by the electropolishing process. Certain gratings within the CO Building Drainage range are electropolished as standard. ll stainless steel products can be electropolished if required to special order.
