Steel Screw Foundation

Steel Screw Foundations provide a robust, corrosion-resistant anchoring solution for ground-mounted photovoltaic (PV) structures. Manufactured from high-strength hot-dip galvanized steel (Q235, 80μ+ coating), these foundations ensure long-term stability and load-bearing capacity in diverse soil conditions-from loose soil to sloped terrain up to 30°. They eliminate the need for concrete, reducing installation time, labor costs, and environmental impact.

Corrosion Resistance

Hot-dip galvanized steel with a zinc coating of 80μ+ offers exceptional resistance to rust and degradation, even in harsh environments such as coastal or humid climates.

High Load-Bearing Capacity

Reinforced pipe design and thick-walled construction (2.5–3.5 mm) enable stable support under high wind loads (up to 60 m/s) and snow loads (1.4 kN/m²).

Quick and Easy Installation

With no curing time required, steel screw foundations can be installed rapidly using standard machinery, significantly shortening project timelines.

Environmental Sustainability

Fully recyclable and concrete-free, this solution minimizes soil disruption and carbon footprint-ideal for eco-sensitive projects.

Applications

Solar Power Plants

Ideal for securing ground-mounted PV systems across varied terrains, including sand, marshland, and slopes.

Infrastructure & Construction

Suitable for fencing, signage, flagpoles, and modular buildings where reliable, non-invasive anchoring is required.

Telecommunications & Utilities

Provides stable support for communication towers and temporary installations in remote or challenging locations.

FAQ

 

 

01.What types of soil are screw foundations suitable for?

They perform reliably in a wide range of soil conditions-including sand, clay, marsh, and rocky terrain-and can be installed on slopes up to 30°.

02.How does the installation process work?

Using hydraulic drive equipment, the screw pile is rotated directly into the ground. No digging or concrete is required, enabling fast and clean installation.

03.Can I request custom sizes or coatings?

Yes. We offer customized lengths, diameters, and anti-corrosion treatments to meet specific project or environmental needs.

04.Are your products compatible with different solar panel brands?

Our screw foundations are designed to support all mainstream PV modules in both horizontal and vertical orientations without additional adapters.
