The Technical Standards of High-quality FRP sheet. 1. Good tenacity. No cracking phenomenon when driving nails in roof installation. 2. Having close combining with color steel plate. Cross-section thickness is uniform. The shape of FRP is consistent with steel plate. 3. Transmittance loss rate is low. No yellowing phenomenon after long term service. 4. Thermal expansion coefficients is close to that of steel plate. No cracking and water leakage in nail driving place because of expand with heat and contract with cold. 5. Light through FRP assumes scattering shape and gentle. 6. Bright and clean appearance, no distinct air bubble and cracking on FRP. 7. Anti-ultraviolet and anti-chemistry corrosion. 8. Anti-ageing and anti-pulverization. 9. Very transparent. 10. Long service life. Mechanics features: Hight steel and height tenacity FRP. Resin Ingredient; Common anti-ageing resin Fiber Intensity: Non-alkali, non-twist, non-glue glass fiber. Surface Treatment: Pasting pet anti-ageing film. Reinforced Bending Line: Having anti-pull reinforced bending lines with longitudinal uniform distribution (it depends on consumers to choose voluntarily whether adding) Glass Fiber; adopting high-quality glass fiber, the content no less than 28%.
