DOUBLE WALL Polycarbonate Corrugated Roofing Sheets:
Twinwall PVC corrugated sheet is the newest product that adopts both PVC high weather resistant engineering plastic and the most advanced triple extrusion technology for one-off processing, which are made of imported extra weather resistant engineering resin. It boasts extraordinary durability in natural environment. The hollow structure provide superb heat insulation for workshop, private and public buildings.
|Length||customized but must be a multiple of wave pitch.|
|Color||Blue, white, blue+white, etc.|
|Accessories||Fixing buttons, screws, gaskets, etc.|
The design of hollow frames uses the theory of heat insulation by floating air to lower the heat conductivity to 0.067/w/m.k, which is as good as the foam sandwich panel. It becomes of the best popular roofing materials for indoor cooling.
2.Firm and aesthetic
The structure of hollow frames doubles the impact resistance and bending ability. It can afford 100N load, that is, 100KG per sqm. It is 2 times more than normal corrugated sheet. The tensile strength reaches 202N.It can be used between -20°C to 88°C. All these numbers above can lower the cost of the steelwork roofing and make the appearance more aesthetic.
3.Good Sound Insulation
Sound Insulated by air dielectric, sound insulation property is Grade One.
4.Patent design, impermeable and leakproof
The overlapping design makes the installation easy, impermeable and leakproof!
5.Colorful and Durable
We apply the advanced ASA extruded technology and coat ASA sunproof material on the surface of the product. The oxygen index reaches 40.8% and the flammability reaches FV-0. We guarantee 15 years for this products and 10 year for the color.
