1. Aluminum alloy (Al6005-T5 surface anodized)
Features: Aluminum alloy brackets are corrosion-resistant, lightweight, beautiful and durable. It usually adopts anodized surface treatment to improve corrosion resistance and can resist erosion in the natural environment to a certain extent.
Application: Aluminum alloy brackets are generally used for solar applications on the roofs of civil buildings, but due to their relatively low self-bearing capacity, they may not be suitable for large-scale solar power station projects.
Advantages: Aluminum alloy brackets are convenient for quick installation on site and can save installation costs. At the same time, their aesthetics also meet the aesthetic requirements of some buildings.
2. Galvanized steel parts (hot-dip galvanizing)
Features: Galvanized steel parts are treated by hot-dip galvanizing process to form a dense zinc-iron alloy layer on the surface, which significantly improves the corrosion resistance of steel. This material has stable quality, strong bearing capacity and simple installation.
Application: Galvanized steel brackets are widely used in civil and industrial solar photovoltaic and solar power stations. Its high bearing capacity and good corrosion resistance make it the first choice for large projects.
Advantages: The manufacturing process of galvanized steel brackets is mature, the specifications are uniform, and the quality is stable. In addition, its relatively low price also makes it more competitive in the market.
3. Zinc-aluminum-magnesium photovoltaic bracket
Features: Zinc-aluminum-magnesium photovoltaic bracket combines the advantages of zinc and magnesium. Through specific alloying treatment, it promotes the formation of dense corrosion products, reduces the diffusion rate of oxygen and the reduction rate of oxygen in the cathode area. This bracket performs well in corrosion resistance and has self-healing ability.
Application: Zinc-aluminum-magnesium photovoltaic bracket is suitable for solar photovoltaic projects under various environmental conditions, especially those with high requirements for corrosion resistance.
Advantages: Zinc-aluminum-magnesium photovoltaic bracket not only has excellent corrosion resistance, but also has good strength and stability. Its self-healing ability also reduces the cost of long-term maintenance.
4. Stainless steel
Features: Stainless steel bracket is known for its excellent corrosion resistance and high strength. It can maintain stable performance under harsh environmental conditions and is not easy to rust or corrode.
Application: Stainless steel bracket is usually used in projects with high requirements for corrosion resistance and aesthetics, such as photovoltaic projects in marine environments or high-salinity areas.
Advantages: Stainless steel brackets are extremely durable and require almost no additional anti-corrosion treatment. Its aesthetics also meets the needs of some high-end projects.
