The material of the solar bracket / solar mounting structure is generally stainless steel, aluminum alloy, hot-dip galvanized carbon steel. What are the advantages of aluminum alloy solar brackets? 1. As we all know, the density of aluminum is lower than steel, only 2.7kg/dm3, and the weight is lighter. 2. Anti-natural corrosion, aluminum placed in the air can react with oxygen to form a protective layer of aluminum oxide, which enhances the corrosion resistance of aluminum. 3. Steel brackets and the aluminum frames for solar panels are prone to galvanic corrosion, while aluminum brackets will not. 4. The conductivity of aluminum alloy is very good, so it can balance the current well and prevent some accidents from happening. 5. Easy to process, aluminum alloy is relatively soft, and can be easily processed into required specifications by sawing, drilling, folding and other processes, and the energy consumption in the processing process is much lower than steel. 6. Low temperature resistance, steel is fragile in low temperature environment, and aluminum alloy material contains aluminum metal, which has the property of low temperature resistance. 7. Environmentally friendly and easy to recycle, discarded aluminum alloy brackets can be recycled and reused. Choosing the material of the bracket needs to be combined with the geography, climate and solar resource conditions of the construction site.
