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...
