1) ASA PVC hollow roof sheet making machine consists of extruders, extrusion mould, calibration system, haul-off machine, cutter and stacker.
2) The extrusion mould adopts the latest co-extrusion technology with very precise design with multi-cavities.
3) The shaping mould includes the vacuum calibrating system and special design of cooling runner with excellent cooling effect.
4) The surface UV-layer is co-extruded with ASA/PMMA bright color, which is not easy to fade and keep life longer.
POLYTECH is the pioneer to innovate double wall corrugated vinyl roofing machine in China. We design many premium hollow roof profile, which ensure stronger and reasonable performance of final roof sheet. Hollow roof sheet is made of high quality uPVC resin with anti-UV additives to provide the best heat insulating performance. POLYTECH develop first PVC hollow corrugated roof line in 2009. We already sold out more than 38 lines all of the world, especially Indonesia market.

Applications and installation:
Compared with traditional plastic roofing sheet, this twin-wall hollow roofing sheet is better for heat and sound resistance. It is suitable for tropical weather with advantage of anti-corrosion, rust-proof, strong durability, and beautiful appearance, easy and fast installation. Because of the stronger rigidity, the twin-wall hollow roofing sheet is widely used in the factories (including chemical and treatment plant), sports stadium, schools, agriculture industry, marine, warehouse.
POLYTECH design special connected parts which is easy for people to make installation and better function for waterproof and windproof.
