Product Advantages
01. Weather-resistance
The frame material has passed DH3000,TC600,HF30, DH2000+UV400 and salt spray level 8 test, and the strength retention rate is greater than 80%, which can ensure the safety for more than 25 years.
03. Wear-resistant
The wear resistance of Zhenshi composite frame is 10 times that of the paint coating. It requires more than 2000L abrasive to wear through the surface by flalling abrasive.
05. Heat Resistance
The heat deformation temperature of the frame material exceeds 230℃, and the Coefficient of thermal expansion is consistent with the glass, which reduces the risk of glass bursting.
07. Environmental Protection
Compared with aluminum alloy frame, the carbon emission of zhenshi composite frame is reduced by more than 80% per ton.
02. High Strength
The axial strength of the frame is 5 times that of the aluminum alloy, and the deformation of modules is smaller under the same load, which is conducive to protecting thecells.
04. Insulation
The volume resistivity of the frame is 1*1010Ω·cm.
It is an electrical grade insulating material, so the modules can be free from grounding.
06. Corrosion Resistance
The frame is resistant to strong acid, strong alkali, metal salt, industrial detergent and other chemical reagents, suitable for high corrosive areas such as sea, beach and saline-alkali areas.
08. Anti-burst
The elastic modulus of the frame material is lower than that of tempered glass, and it has dynamic load damping effect under high-frequency wind load, which is not easy to form resonance, and can effectively alleviate the risk of glass burst.
