About Solar Earth Screw Co., Ltd
Solar Earth Screw Co., Ltd is a professional manufacturer of ground screw foundations and helical pile systems, serving solar EPC contractors, construction companies, and infrastructure developers worldwide. We specialize in engineered foundation solutions designed for structural reliability, corrosion durability, and full international standards compliance.
Who We Are
Founded with a clear focus on renewable energy and sustainable construction, Solar Earth Screw Co., Ltd delivers precision-manufactured ground screw systems for residential, commercial, and utility-scale applications. Our products are widely used in solar ground mount foundations, utility-scale solar farms, fencing systems, deck supports, greenhouses, and light infrastructure projects.
Our engineering philosophy integrates structural steel design, geotechnical performance validation, and corrosion protection standards into every product we manufacture. We supply foundation systems engineered to meet global codes, including ISO, EN, ASTM, and ICC frameworks.
Our Mission
Our mission is to provide reliable, cost-efficient, and standards-compliant ground screw foundation solutions that reduce installation time, eliminate concrete usage, and minimize environmental impact. By replacing traditional concrete footings with engineered helical systems, we help developers accelerate project timelines and reduce carbon footprint across solar and construction industries.
