2 MOLDED GRATING PROCESS Molded grating is manufactured in an open, heated mold that resembles a large waffle iron. Continuous reinforcements are placed in the mold in alternating layers and thoroughly wetted out with resin. This continuous process produces an integral, one-piece construction, which offers excellent corrosion resistance as well as bi-directional strength. When the weaving process is completed, the mold is heated to cure the panel. If the grating is to have embedded grit, the mold will receive the grit at this time before the part is cured. After curing, the part is extracted from the mold. The standard part would have a meniscus (concave) top surface for slip resistance. Should a standard grit surface be specified, the grit would be bonded to the top of the completed grating panel as a secondary operation. MOLDED GRATING Liquid resin and continuous fiberglass roving are systematically laid in the mold, layer after layer manually, to produce the desired thickness and panel dimensions. The finished molds are set aside for a predetermined time to allow the panel to cure. The panel is then ejected from the mold. The molds are cleaned and prepared for the process to begin again. The one piece interwoven square mesh construction of molded grating produces two primary benefits: maximum corrosion resistance and high strength. Because the grating is "cast" in one piece, there is no mechanical joint between bearing bars. The high percentage of resin in molded grating offers superior corrosion resistance. The molded grating with a square mesh pattern offers increased load capacity and panel utilization due to this bi-directional trait. Cutting access holes in the molded grating does not weaken the panel and does not require additional or costly supports.

4 DESCRIPTION NON-SLIP Composite Grating s integral grit top surface provides outstanding anti-slip protection for personnel in wet and oily environments. The grit is embedded in the top surface of each panel prior to curing. This combination of integral construction, plus depth of the embedded grit, creates a long-lasting maximum anti-slip top surface. CORROSION RESISTANCE Over a wide PH range (both acidic and caustic) is achieved by use of a premium grade resin system. FRP grating will outperform metallic grating when exposed to continuous submersion, splashing, spills, fumes or gases. Corrosion is a major problem for metal grating, stair treads and other products in many different industries such as chemical plants, food and beverage factories, water and wastewater facilities, power facilities. Molded grating are particularly designed to provide safe, long lasting and economical and worry-free solutions environments where chemicals and other corrosive materials attack and destroy metal. FIRE RESISTANCE Composite Grating is available in various resin systems, two of which meet the Class 1 flame spread rating of 2 or less, in accordance with ASTM E-84 Tunnel Test Method. If a flame spread of 1 or less is required, it will be available in request. NON-MAGNETIC The non-magnetic properties allow the Composite grating to be used in sensitive installations where the inherent magnetic properties of metallic grating would prove unsuitable. IMPACT RESISTANCE The impact resistance of Composite Grating allows repeated deflection without permanent deformation. A certain amount of deflection can occur with loading. However, once the load is removed, the grating will return to its original shape, unlike metallic grating, which will remain deformed and require costly repairs or replacement.

5 NON-SPARKING The non sparking qualities of Composite Grating systems are ideally suited for those installations where hydrogen or other combustible gases may be found and which may explode or cause a fire from sparks produced from accidental dropping of tools onto the grating. MAINTENANCE FREE The use of Composite Grating virtually eliminates maintenance costs since painting is not required, and UV inhibitors protect against degradation from the sun. LIGHTWEIGHT Composite Grating weighs about one-quarter as much as steel grating. Two men can easily handle full panels, without the need for hoists, pulleys or dollies. If the Composite Grating needs to be moved for cleaning, maintenance or utility access, there is less chance of back injuries. The lightweight design of the grating reduces installation and fabrication costs, weighing only 12 kilos per sq mtr for 2mm and 18 kilos per sq mtr for 38mm. RAISED FLOORS Many plant operations have a need for slightly elevated Floor Grating. Fixed or adjustable pedestals can be used for applications up to a height of mm. Plastic insert mouldings, which raise the Composite Grating panels 7mm off the floor, are ideal for allowing liquid drainage below the Grating. STANDARD BEARING SURFACES On most installations, a minimum of 38mm bearing support should be provided under the edges of Composite Grating panels.

6 DESIGN The design procedures associated with Composite Grating are entirely different from those associated with other materials. The prime consideration in designing with this reinforcement is allowable deflection as opposed to ultimate loading used with steel and aluminium. The reason for this is the inherent elasticity of reinforced plastic, permitting far greater deflection than steel, without the danger of structural failure. and deflection tables are available on request. COST SAVINGS In a review of costs, Composite grating showed significant savings over the use of stainless steel grating, and when consideration is given to life cycle costs, combining anti-slip benefits, the saving over the use of metal grating alternatives is quite considerable. NON-CONDUCTIVE The non-conductive properties make Composite Grating ideally suited for work platforms and flooring situated in electrically hazardous locations. LOW INSTALLATION COSTS Composite Grating weights considerably less than conventional metal gratings, and is easier and less expensive to transport, install and remove. Only simple hand tools are required for installation and removal, eliminating the need for costly equipment and labour costs associated with heavy lifting, cutting and welding. HIGH STRENGTH-TO-WEIGHT RATIO Molded grating manufactured as a composite of continuous strands and high quality resin is integrally constructed for strength, it is less than one-half the weight of steel grating allowing easy removal for access below floor level and installation with no heavy equipment and less manpower. Properly installed, molded grating meet specificied load requirements for steel and are more impact resistance than metal.

7 ERGONOMIC Employees are experiencing fatigue after standing on solid concrete and heavy non-adjustable galvanized steel platforms all day, molded grating is the best solution to ease the strain on the backs, foot and legs of workers increasing worker comfort and productivity due to its nature slight resiliency that makes them comfortable to stand on for a long period. CONDUCTIVE GRATING Composite Conductive Grating provides a specially formulated carbon, black surface, which will eliminate hazardous static electricity when properly grounded. This anti-static property is most advantageous in high-tech electronic industries where sophisticated equipment may be damaged due to static electricity. It also provides a safe environment in combustible areas by not allowing static sparks. Conductive Grating can be used in Railway Fuel Stations, Circuit Board Manufacture, Oil Refineries, Underground Mining Operations, Ammunition Factories etc. HIGH PERFORMANCE Composite structural Composite grating materials have demonstrated a proven ability to withstand the harsh side effects of corrosive conditions better than galvanized steel. For many years, composites have been reliably used in traditionally corrosive industries such as chemical processing, plating and marine construction. While the cost of material is an important criteria in the design of a project, it does not reflect the total cost of the project. Beyond material purchase price, the engineer also should consider the related costs of installation, maintenance over time and replacement of debilitated materials.
