Fasteners are particularly important in solar mounting brackets. If the solar panels are loosened due to incorrect installation, it will cause great losses.   Today, let's discuss the correct way to install fasteners.   First of all, the spring washer needs to be placed behind the nut, so that the elastic force of the spring washer can be used to increase the friction between the nut and the bolt to prevent loosening.     Second, flat washers must be placed under the bolts and nuts to increase the pressure-bearing area. If there are spring washers installed, the spring washers need to be placed on top of the flat washers, closer to the nuts.   Third, the number of flat washers should not be too much. If there are only bolts, only two flat washers can be placed at...

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...
