Insufficient anodizing thickness of solar bracket and insufficient galvanizing thickness lead to rust.
Solar support condition of photovoltaic power station is closely related to the service life and safety of the power station. Solar brackets can be divided into galvanized steel brackets, aluminum alloy brackets, and stainless steel brackets according to their materials.
Galvanized steel is the most commonly used and the most cost-effective. For customers who are looking for beauty and have low strength requirements;
Aluminum alloy brackets can be used, which is slightly more expensive; for customers who are looking for beauty and have higher requirements for strength;
Stainless steel brackets can be used, but the cost is the most expensive.
1） Insufficient steel thickness (1.5mm) leads to insufficient strength, and the power station is at risk of being destroyed by strong winds;
2）If the thickness of galvanizing is not enough, or if electroplating is used instead of hot-dip, then the anti-rust ability is very poor.
For customers who use C-shaped steel brackets, the steel thickness is generally 2.0mm, and hot-dip galvanizing is used for anti-rust treatment. The galvanizing thickness is generally not less than 60um.
In typhoon-prone areas, the steel thickness should be increased to 2.5mm. In areas with severe salt spray erosion along the coast, the thickness of galvanizing should be increased to 80um or 100um.
