How To Choose The Material And Type Of Solar Bracket?

The selection of solar support materials and installation methods requires strict calculations to determine. In addition, affected by the texture, climate, environment, and other factors of the installation site, weather resistance is also one of the bases for selection. For example, the installation site with a soft texture can be fixed by ground anchors. If the historical maximum wind speed or maximum snow volume is within a certain range, you can properly choose materials that can meet the requirements and have a low cost. 

At present, the materials of solar brackets mainly include aluminum alloy (Al6005-T5 surface anodized), stainless steel (304), galvanized steel (Q235 hot-dip galvanized), etc. Among them, stainless steel has the highest cost, good weather resistance, and can be recycled. 

Aluminum alloy brackets are generally used in solar energy applications on the roofs of city buildings. Aluminum alloys have the characteristics of corrosion resistance and are lightweight, beautiful, and durable, but their low bearing capacity cannot be used in large-scale solar power plant projects. In addition, the price of aluminum alloy is slightly higher than that of hot-dip galvanized steel.

The galvanized steel bracket has stable performance, a mature manufacturing process, high bearing capacity, and easy installation. It is widely used in civil and industrial solar photovoltaic and solar power stations. Among them, the section steels are all produced in factories, with uniform specifications, stable performance, excellent anti-corrosion performance, and beautiful appearance. It is worth mentioning that the on-site installation of the combined steel bracket system only needs to use specially designed connectors to assemble the channel steel. The construction speed is fast and no welding is required, thus ensuring the integrity of the anti-corrosion layer. The disadvantage of this product is that the connecting piece has a complicated process and a wide variety, and has high requirements for manufacturing and design, so the price is high. Another disadvantage of galvanized steel is that the final recycling value of the material is not as high as the first two.
