How to choose the anti-corrosion solution for photovoltaic brackets?
Oct 20 , 2026
The photovoltaic bracket industry uniformly adopts ISO 12944 atmospheric cohesiveness classification (C1 – CX) as the grading basis, and then deducts the coating thickness and process according to the material (carbon steel/aluminum alloy/fastener). The selection logic is: first determine the level based on the on-site environment, and then match the anti-corrosion plan according to the mater...
