DESCRIPTION / SPECIFICATIONS OF GOODS The Goods to be supplied by the Supplier include the following: The scope of works including:- 1. Supply, delivery and installation of pallet racking system as follow:- i. 6000H x 2700L x 900W x 4 Level ii. (2,000 kgs UDL/Level) Interlock Pallet Racking (Back to Back) 6000H x 2700L x 900W x 4 Level (2,000 kgs UDL/Level) complete with pallet support bars, column guards, safety barriers, pallet back stopper painting The specification of the pallet racking system is shown as follow:- Item Description (A) Interlock 600 SCHAEFER or equivalent All components are manufactured to a code of practice as recommended by Storage Equipment Manufacturers Association (SEMA 1986) and the Australian Standard for steel storage racking (A.S. 4084 1993). All steel profiles used are manufactured to guaranteed minimum yield point of no less than 400 mpa using high grade imported steel and tensile strength of no less than 540 N/mm2. Frame The post sections are cold formed on a purpose built rolling mill into a C section, returned flanges have punched holes at 50mm spacing to accept bolted bracing sections. The front face is punched with twin slots set at 50mm increments to accommodate the end connector. Interlock frames are available in 4 gauges up to 3mm in standard, medium, heavy and extra heavy sizes and in two post widths of 90mm and extra wide 115mm. Diagonal bracing using cold form channel section steel profiles are bolted in a warren pattern at 600mm centres using M10 x 60 high tensile nuts and bolts, throughout the height of the frame. Horizontal braces are fitted to the lower and upper most diagonal braces to ensure frame rigidity, steel tube spacer bars are fitted to horizontal bracing members on single bracing points. Bolted base plates are fitted to each frame, two types are available - a standard duty 105 x 100 x 4mm or heavy duty 180 x 100 x 6mm. Shims of 1mm and 3mm are available to ensure rack alignment and level. Frame loads are dictated by the height of the first beam level and subsequent beam levels, the length of the unrestrained leg and the number of beam levels and bays in each rack. Frame loading will derate as the length of the unrestrained leg is increased. Ref. No. PMS 152/17) 1
Manufacturer shall advice the actual frame load, should beam levels be repositioned after initial design and installation. The safety factor of all frames is 1 : 1.54. Beams Box beams are fabricated from twin cold rolled G section interlocked to form a rectangular box section, and welded at each end to a compatible steel connector, to effect attachment to the frame. Open section beams are available for light duty pallet load or shelving applications. Beams are adjustable on vertical pitch of 50mm. Each beam has a safety lock to prevent accidental removal. Deflection is limited to span over 200 i.e. a maximum of 13.50mm under listed maximum weight loading for a 2700mm span. The safety factor is 1 : 1.54 for yield on all loadings shown. All weight loads are tested to FEM/SEMA recommendation of span over 200. 1.1 Upright I600 Post 50mm upright pitch Cold Forming Process on the most updated technology German machine C-Section, Front-Centre-Ribbed, so called PR600 Fritz Schaefer pitch profile, (Schaefer worldwide profile) One piece section, no splices 1.2 Frame Standard JIS G 3101 SS400 Min Yield Point 320 390 N/mm² Min Tensile Strength 400 490 N/mm² Structural engineering calculations use a Y.P of 390N/mm² 1.3 Beam Interlock I600 Uprights Ref.

System Accreditation 2.2 Installation Tolerances (FEM 10.3.01) The operation of this warehouse falls under CLASS 400 (as per FEM 10.3.01). The racking for these classifications requires the following finished erection tolerances: HORIZONTAL LIMITACIONS X : Along the aisle direction Z : across the aisle direction The tolerances apply to assembled but unloaded racking Measuring Description of Tolerance Tolerance Class 400 Code A Variation from nominal dimension of the clear + /- 3 mm entry width between two uprights at any level At Variation from nominal dimension of the total rack length, cumulative with the number of bays n measured + /- 3n mm B Cx Cz D E F Jx Jz Misalignment of opposing racks across an aisle, cumulative with the number of bays n measured near floor level Out of plumb of each upright in the X direction (the larger of) Out of plumb of each frame in the Z direction (the larger of) Variation from nominal dimension of the rack depth Single or double frames Variation from Nominal dimension of the aisle width near from level Variation from nominal dimension of the straightness of an aisle measured near floor level with regard to the Aisle System X Datum Line Upright Straightness in the X direction between beams spaced h apart (the larger of) Initial Curve of an upright frame in the Z direction + /- 10mm or + /- 1.0n + /- 10mm or + /- H /350 + /- 10mm or H /350 + / - 3 mm + / - 20 mm + / - 15 mm + /- 3mm or + /- H /400 Un-spliced frame : H / 750 Un-spliced frame : H / 500 Ref.

(C) SURFACE PROTECTION (PAINTING FINISH) The INTERLOCK Pallet Racking Systems are subjected to the highest standard of powder coating finish using the most environment-friendly powder coating plant to date anywhere in the world. Section of up to 9,000mm length, 2,000mm high and 750mm wide with weight of up to 600kg are transported through the plant by means of an overhead powered conveyor approximately 300metres in overall length. The plant as a whole consists of the following units: Ref. No. PMS 152/17) 6
5 Stage Spray Pre-treatment Plant: The clean and phosphate the work pieces using a cascade-rinsing recycling technology. Dry-Off Oven: To dry the wet pre-treated parts. Powder Coating Booths: Designed for minutes-color change, electrostatic powder coating and recovering system. ;Powdered Conveyor To link and transport parts to the various units of the plant. Parts contaminated with surface oil and dirt are first treated in the 5-stage-spray pretreatment plant with the following sequence of processes: Cleaning and degreasing at 60 C to remove oil and dirt. Rinsing with clean circulation water to remove excess degreasing chemical. Parts are then iron-phosphated at 60 C to prevent corrosion and enhance powder adhesion. Final two rinsing processes with deminerlised circulation water (approx. 30μs/cm) are to ensure parts are absolutely clean before powder coating process. The specification for the entire pre-treatment system is to achieve high quality standard products. After the pre-treatment process, the parts are dried in the dry-off oven approximately 80 C-130 C for 10 minutes to ensure the quality of phosphating is achieved. The powered variable speed overhead conveyor (2.5 5.0 m/min.) then transports the parts to the powder-coating booth. Here, electrostatic coating process is carried out automatically in a mobile booth, if required by hand, to uniform thickness between 55 μm to 65 μm. Quick colour change is achieved by two roll-on and roll-off fully automated powder recovery booths. The modified epoxy powder is manufactured by a licensed Malaysian Company with powder formulation from Belgium to create a sophisticated structure guaranteeing the superiority of quality of the product. Finally the coated parts are baked in the curing oven at a uniform temperature of 180 C - 200 C for 20 minutes to ensure even cross polymerisation. The parts are then unloaded, checked against quality standards before packing for delivery or storage. The greatest satisfaction for investing in this high technology powder coating plant is the ability and flexibility to manufacture high-quality storage and industrial installation products to meet customers demands.
