Cold Room Panels

Wong Brothers have over 50 years manufacturing experience in refrigeration. Our products range covered prefabricated polyurethane panels, composites truck bodies, commercial and industrial refrigeration systems, etc.

Our prefabricated polyurethane panels manufacturing plant is the most advanced in Malaysia. All products are manufactured according to British 4840 standard. Our prefabricated polyurethane panels is designed for reach-in, walk-in, drive-in cold room, hot room, refrigerated warehouse, burn-in room, clean room, and etc.

Polyurethane is the most effective heat insulating materials known to date. Majority of the new cold rooms constructed in the United States, Japan, Korea, Taiwan and Europe are insulated with polyurethane. With the use of polyurethane, thickness of the panels can be reduced by 40% while still maintaining effective heat insulation as of other materials.

In addition, Polyurethane is thermally stable (does not shrink or deform), fire proof (reduce fire risk), strong, vermin proof, non-moist absorbing and has a very low water permeability property.

Summary of specification
Construction
WB Prefabricated Polyurethane Panels is manufactured to BS 4840 on modular principle with each panel being interlocked with its neighboring and drawn tight by cam-lock.
Fire Safety
The panels are compliance to BS 467 class 'O' building materials. The polyurethane is classified as self-extinguishing according to BS 4735 and ASTM D-635.
Door
Various designs of hinged or sliding door are available. Alternative door sizes and a full range of door furniture are available upon request. Doors are insulated with formed polyurethane and fitted with lever handle with internal safety release handle.
Insulation
Each panel is 'foamed in place' with self-extinguishing, CFC free polyurethane using high pressure injection technology. This is to give a product of very low thermal conductivity of 0.020 W/m.K with high mechanical strength at low density (45kg/m3) and 95% closed cell content. Thickness is available from 50mm, 75mm, 100mm, 125mm to 150mm for various temperature, structure and application.
Finish
The metal should be roll-formed with 107mm spacing for added strength.
Standard: 0.50mm color bond
Optional: 304/2b stainless steel, stucco aluminum or PVC coated steel in various thicknesses.
Modular panels
Panels are made into 300mm, 900mm and 1200mm widths with 300mm X 300mm corner panels for maximum strength and perfect alignment. Standard panels of 2400mm, 2700mm and length up to 12.0 metre in single piece should be used. All panels are precisely formed in a hydraulic steel mould with controlled temperature.
Door
Various designs of hinged or sliding door are available. Alternative door sizes and a full range of door furniture are available upon request. Doors are insulated with formed polyurethane and fitted with lever handle with internal safety release handle.
