Nowadays, the solar ground mounting system is generally made of aluminum alloy or carbon steel. Carbon steel materials are usually: Q235 and Q345. It will effectively improve the anti-corrosion ability of the bracket after hot-dip galvanizing treatment. HDG is the abbreviation of hop dipped galvanized. Where do you need to use HDG solar ground mounting brackets to install solar brackets? In coastal areas, strong wind areas, heavy industrial areas, suburbs, etc. These are places where the environment is more corrosive . So you need to use HDG solar ground mounting bracket to prolong its service life. HDG solar ground mounting bracket not only has strong corrosion resistance, acid and alkali resistance, but also strong wind resistance, earthquake resistance and load bearing capacity. The thi...
