The sea blue color steel roof tiles is made from reinforced and weather resistance PVC raw material according to national building materials industry JC/T562-94 standard. After tested by nation assigned authoritative department, main performance index as following:
1. The transparent tile has good transparence performance, light transmittance reach 5%.
2. Chemical corrosion resistance
3. Non-toxic, no asbestos which could cause cancer, conforms to world sanitation standard; Mosses and other microbe can not grow on it. 4. Safe and reliable, does not self-ignite and help burning when meet with fire
5. Good fexibility and shock resistance, even if wheel mill on it could also restore the original condition (tensile strength 42Mpa)
6. Good heat insulation (thermal conductivity is 0.16Kcal/mhrº C)
7. Windstorm resistance under correct construction(able to withstand gale of 120 kilometer/h)
8. Weather and ageing resistance (scientific instrumental measurement for 130, 000 hours/+± 65º C does not deform, effloresce and decorticate)
