Array Technologies , one of the world’s largest manufacturers of ground-mounted systems used in solar energy projects, today announced it has entered into a multi-year supply arrangement with POSCO, one of the world’s largest steelmakers, to diversify and strengthen its global supply chain. Array will now have access to POSCO’s proprietary PosMAC® material, an alloy coated corrosion resistant steel. POSCO will cooperate with a Korean local fabricator to convert the products into components for use at Array’s global solar project sites. POSCO’s South Korean headquarters will position Array to serve customers in the U.S., Australia, and other emerging solar markets more efficiently with a stable supply.

“The arrangement with POSCO is indicative of our ability to reliably supply our global customer base with the highest quality materials,” said Stuart Bolland, Chief Operations Officer of Array. “This strategic partnership will enable us to reduce trucking mileage to West Coast of the U.S. project sites and ultimately bring greater flexibility and resilience to our supply chain. Further, we are thrilled to offer our customers a superior product in the PosMAC® corrosion resistant technology and partner with a company that shares our commitment to ESG values.”

PosMAC® has anti-corrosive and anti-sand erosion properties that make it resistant to chemicals, red rust and various solutions encountered in the steelmaking machine process.

“As the first Asian steelmaker to commit to carbon neutrality, POSCO is taking initiative to build clean energy infrastructure and move toward a new energy era. We are thrilled to be a supplier of choice for Array, an established leader in the renewable energy space,” said Sanggyun Kim, Head of Construction Steel Materials Marketing Office of POSCO. “We believe this fruitful partnership will showcase the many benefits of our manufacturing process and the advantages of our product. We look forward to being a meaningful contributor to Array’s advanced solar tracking.”
