PVC Roofing Sheet Twin Screw Extruder With Corrugated Roll Forming Machine For Steel Factories
1. Product advantage:
This tile is the best replacement to conventional asbestos, metal G.I. sheets and PVC sheets considering the heat insulation, sound insulation, water resistance, chemical and alkali resistance, corrosion proof, fire retardant, eco friendly, easy to install and move, light weight as well as cost effective in installation (as less steel and less overlap), as per the efficiency and benefits it provides. It can save construction cost upto 50%.
Apart from its numerous benefits, its salient features include heat insulation upto 35% (highly energy efficient) and it can withstand temperature upto 70 degrees Celsius to - 40 degrees Celsius.
PVC+ASA two layer co-extrusion Roofing tile .ASA layer for anti-UV for 30 years life.
2. Product application:
Product are used for factories, warehouses, sheds, farmers market, hoardings, walls, temporary shops, sheds and other very suitable insulation.
