Polycarbonate Corrugated Sheets

Detail Information

Description :

1. Impact-Proof: our pc sheets have high impact strength(approximately 250 times that of glass and 3-5 times that of ordinary corrugated sheets)that makes them virtually unbreakable.
2. TRANSPARENCY AND LIGHT TRANSMISSION: excellent light transmission .its transparency is remarkably comparable to that of glass.
3. Weather-Proof: as sheet's surface have been treated with anti-UV ray agent to resist resin's fatigue caused by the sun, yellowing on sheets' surface would not occur. the protective uv-coatelayer can maintain excellent light transmission of the sheets and prevent the sheets from becoming yellowing.10 years' quality warranty is provided.
4. Flame-Proof: compared with fiberglass(frp),pc sheets have remarkable characteristics of flame resistance and extinguishment to inflammability.
5. Heat and Cold Resistance no deterioration or deformation from-20 to 135 centigrade.
6. Installation and Processing: characteristic of light weight makes the sheets easy for transportation,handling and installation,with good processing performance in drilling, sutting and installing without having risks of breakage.
