The Technical Standard of High-quality GRP
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 GRP 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 GRP assumes scattering shape and gentle.
6. Bright and clean appearance, no distinct air bubble and cracking
on GRP.
7. Anti- ultraviolet and anti- chemistry corrosion.
8. Anti- ageing and anti- pulverization.
9. Long service life.
