ground screw

Ground screw is a large screw, using special machines will drill into the bottom, can be achieved with the concrete base the same strength and tensile force. The cost of this method is more lower than the traditional concrete method, and the disintegration of easy to remove, and can be repeated use. Therefore, now the solar power generation equipment are used this ground screw to stability the foundation.

Keystone Ground Screw is specially developed for the maximum flexibility in designing for both residential and commercial solar mounting system, which can be applied to various soil conditions and/or can be customized according to Clients’specific requirements.

1) Quality Guaranteed: Treated with a layer of zinc, ground screw enjoys a longer life span with better corrosion resistance.
2) Versatile mechanical innovation: Unique structural design ensures a much better pull-out and load bearing capacity.
3) Application is wide that can be used in all types of soil and all type of structures.
4) Easy Installation,remove and relocate: Highly pre-assembled structures with minimal components and the adaption of hydraulic pile hammer ensure a quicker and easier installation with less labour cost, which takes 2 minutes on average only to ram a ground screw.
5) Environmental- friendly application: Compared with concrete bases, ground screws can be fully recyclable and cost effective, while produce little waste and can easily be removed.

Ground screws when used directly into the inner of earth，without digging, backfilling process, does not destroy the surface.

On the grass, planting belt also easy construction, no need of transplant trees, flowers etc..
