Solar Panel Ground Screws

Reliable Solar Panel Ground Screws Manufacturer in China

Solar panel ground screws are an innovative and eco-friendly foundation solution for solar panel installation. They are made of Q235 steel and are treated with hot-dip galvanizing to resist corrosion and weathering. These screws come in various lengths, tailored to the size of the solar panel system, providing a secure and stable foundation. The installation process is straightforward and direct, with no significant environmental impact, as there is no vibration, soil displacement, or high noise levels during the pile driving process.

Galvanizing and Moulde

To protect against corrosion, the ground screws undergo a hot-dip galvanizing process. This involves dipping the steel into a bath of molten zinc to create a robust, protective layer.

Quality Control and Shipment

Quality Control includes checking the dimensions, thread quality, and the thickness of the galvanizing layer. All of the screws are typically bundled together and may be protected with wrapping to prevent damage during shipping.
