Ground Screw Foundations
The American Solar Ground Screw Solution
Our product seamlessly integrates with EPC preferences and all major tracker, fixed-title systems, and cable management systems. We are vertically integrated, owning our supply chain, production, and delivery for quality assurance and lead times as short as two weeks.
With two centuries of tradition and innovation, ASA proudly holds long-term partnerships with businesses across industries and the federal government. The same manufacturing expertise used for data storage, energy storage, and government defense is applied to these ground screws, developed with solar project experts for optimal performance.
High-Quality
Our domestic steel manufacturing process provides long-term stability and durability for even the most challenging projects. ASA’s metals have proven credibility with EPCs across industries, built to last and backed by our renowned customer service.
Shorter Lead Times
ASA owns the supply, costs, production, delivery, and performance of its products, all of which are produced in the US. Our vertical integration, onshore production, and partnership approach can reduce lead times to less than a month.
Seamless Integration
Two centuries of legacy engineering led to the engineering of this ground screw. Our precision-formed threading process creates the drivability and axial capacity needed across different terrains. It’s available in standard and customizable options for all major tracker, fixed-title systems, and cable management systems.
Traceable and Reliable
ASA has full control of our supply chain and manufacturing process, delivering a bankable domestic steel product that’s built to last. Built by a team with a reputation for strong partnerships, our ground screws are fabricated in a dedicated facility in New Hampshire to ensure precision.
A Partner You Trust
We’re an independent ground screw producer that seeks to understand, rather than compete with our tracker customers. This product was developed with experts in tracking and racking systems for optimal alignment with your business needs and structural compatibility for installation.
