Steel is one of the most commonly used materials because of its high strength, durability, and relatively low cost. Steel can be processed, such as cutting, bending, and welding, to adapt to different sizes and shapes of solar panels.

Hot dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. Hot dip galvanized steel undergoes complex physical and chemical reactions with the molten plating solution, forming a corrosion-resistant and tightly structured zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate, so its corrosion resistance is strong. Very suitable for outdoor photovoltaic brackets.
