The Technical Standard of High-quality FRP
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 coefficient 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. Long service life.
