Ground Screw - An Important Role in Solar Power System

Ground screws used in solar power system.

GS-01: Ground screws can be used in solar power system.

Ground screw is a kind of drilling pile with screw for driving under the ground more easily. Meanwhile, the screw increase the contact area so that it grasp earth more firmly than other traditional post anchor. So it can be used in loose earth, sandy soil, marsh, bedrock and the slope of less than 30 degree.

The ground screw we supply has stronger bearing capacity, pull-out resistance and horizontal resistance, which make the ground screw resistant to the side friction occurred when screwing into the ground. The surface of the ground screw is galvanized, which means it is corrosion resistant and anti-rust. So it has a long life and can be reused. Additionally, it has better stability for saving the installation time and costing effectively.
