Ground Screws
Product Overview

Ground Screws

Ground screws provide a cost-effective, rapid-deployment alternative to concrete foundations for ground mount solar installations. Manufactured from hot-dip galvanized Q235B steel, these helical anchoring solutions are driven directly into the soil using hydraulic machinery — eliminating excavation, concrete pouring, and curing time entirely.

The helical screw design provides superior pull-out resistance in sandy, clay, and mixed soil conditions. Hot-dip galvanization ensures 25-30 year corrosion protection in aggressive soil environments. Customizable length, pipe diameter, and flange dimensions accommodate project-specific soil conditions and structural load requirements.

For EPC contractors managing ground mount solar projects, ground screws reduce foundation installation time by up to 50% compared to conventional concrete foundations while minimizing site disturbance and environmental impact. Multiple screw types are available depending on soil conditions — a pre-installation soil test is recommended to determine the optimal specification.

Why Choose Ground Screws

Key Advantages

50% Faster Than Concrete

Hydraulic installation eliminates excavation, pouring, and curing. Ground screw foundations can be installed in minutes per point — up to 50% faster than conventional concrete foundations.

Terrain Adaptive

Multiple screw types accommodate sandy, clay, rocky, and mixed soil conditions. Customizable length and diameter match project-specific soil requirements with pre-installation soil test guidance.

Zero Concrete Required

Eliminates concrete mixing, pouring, formwork, and 7-28 day curing periods. Reduces material logistics, site waste, and overall foundation cost for ground mount solar projects.

25-30 Year Galvanized Protection

Hot-dip galvanized Q235B steel provides superior corrosion resistance in aggressive soil environments. Designed for 25-30 year service life matching the solar array's operational lifespan.

Frequently Asked Questions

Ground screws offer faster installation (up to 50% time savings), lower costs, and minimal site disruption compared to concrete foundations. They provide equal or superior structural integrity and can be removed and reused if the solar array is decommissioned — unlike concrete which becomes permanent site waste.
Yes. Multiple screw types are available for sandy, clay, rocky, and mixed soil conditions. A pre-installation soil test is recommended to determine the optimal screw specification, length, and installation torque for each project site.
Hot-dip galvanized Q235B steel construction provides 25-30 years of reliable performance in most soil environments, matching the operational lifespan of the solar array. The galvanization layer thickness can be increased for projects in highly corrosive soil conditions.
Yes. Length, pipe diameter (standard 76mm), and flange diameter (standard 200mm) are all customizable to match project-specific soil conditions and structural load requirements. Contact Megawa engineering for custom specification recommendations.
Ground screws are driven into the soil using hydraulic pile-driving machinery mounted on excavators or dedicated screw-driving equipment. Installation is rapid — typically minutes per screw — and requires no excavation, formwork, or curing time.
