corrugated roof sheet heat proof roof tiles sheet

corrugated roof sheet heat proof roof tiles corrugted sheet Heat Proof PVC Roof Tile has excellent features such as heat proof, fire resistant, sound proof and corrosion proof. According to a series of our professional experiments, its heat proof property, compared with steel roof sheet, is at least 5 centigrade lower after 10 minute's heating. And it can stay no reaction with acid, alkali and other chemical materials even soaked in the chemical tank of heavy chemical substance. Heat Proof PVC Roof Tile Heat Proof PVC Roof Tile offer the following outstanding benefits: ◆UV ray resistant and corrosion resistant / acid & alkali resistant ( soaked in 60% acid and alkali condition for 24 hours with no reaction ) ◆Fire resistant (GB8624-2006 standards ≥B grade.) ◆Lightweight, saving construction cost by at least 10% ◆water proof (100%) / moisture proof / mould proof ◆Provide insulation from noise and heat (20…
