Earth Screws

Earth Screws are a high-bearing foundation structure designed specifically for soft soils. Their core feature is a widened spiral blade with a diameter of 300-600 mm, which increases the contact area with the soil, thereby enhancing pullout resistance and stability. These piles are suitable for low-bearing soil conditions such as sand and silt, effectively preventing the supporting structure from sinking or tilting.

How are products packaged?

We have pallet for 1700*1050*1150mm and 84 screws one pallet for screw earth.

Product Advantages

Earth screw foundation is an innovative solution for solar power plant foundation engineering, featuring enlarged spiral blades with diameters ranging from 400-800 mm.
1. It increases the contact area with the soil, easily adapting to soft soil conditions and providing stable support for solar mounting systems.
2. Utilizing specialized machinery, it achieves high pile driving speeds, capable of installing nearly 100 piles per day.
3. We hold CE, JIS, and ISO certifications, ensuring reliable quality.

Connection method

Ground earth screws for solar is mainly secured through nut and bolt connections and connected to the upper components. The main features of nut connections are simple structure, simple manufacturing process, low cost, convenient up-and-down adjustment, and a wide range of up-and-down adjustment. They are widely used in photovoltaic power stations, guardrails, billboards, traffic, and other infrastructure projects.
