Founded in 1964, Priefert is one of the largest livestock equipment manufacturers in the world as well as one of the largest steel fabricators to the US solar industry. Family owned and operated, Priefert is headquartered in Mt Pleasant Texas with additional locations in Fort Worth, Texas and Benton, Arkansas. Priefert brings 60 years of steel manufacturing expertise to their investment in Origami steel frame manufacturing, a natural expansion of their commitment to the solar industry. Starting in early 2025, Priefert will manufacture Origami Steel frames from its Benton factory and is prepared to expand lines and locations to support future growth of Origami Steel frames.

Priefert has long prided itself for creating the high-end steel-based equipment American businesses need and for providing good-paying jobs for American workers. Fabricating Origami’s steel solar frames helps us keep doing both. Indeed, thanks to our partnership with Origami, we were able to expand our investments in the solar industry, keep our Benton, Arkansas facility open, keep our current employees hard at work and expand to up to 70 additional jobs over the next three years. This partnership demonstrates American innovation at its finest.

Unimacts-a Zetwerk Company is a leading global manufacturer and supply chain solutions company focusing on renewable energy. The company is one of the major steel manufacturers for the solar industry in the United States, supplying major tracker companies and EPCs with components such as torque tubes, rails, solar piles, solar modules, and drives. Unimacts will manufacture Origami Solar steel frames at its Houston plant, via dedicated manufacturing lines, expected to be production-ready by the end of 2024. With manufacturing capabilities in the US, Mexico, Europe, India, and Vietnam and efficient global supply chains, Unimacts can quickly expand both in the US and globally to support Origami Solar steel frame growth.

The American solar industry understands that a domestic supply chain for steel solar frames dramatically reduces risk to companies and to the industry writ large. The steel frames we send from Houston to any production facility in the lower 48 states will never get stuck in customs or be forced to wait in line at a port; they can go from our facility to a module manufacturer in just a day. ‘Always on’ module manufacturers will not have to pause operations for a lack of solar frames. What’s more, given steel solar frames’ extensive testing for both structural integrity and corrosion resistance, solar project developers need not worry about frames failing. We’re ready and eager to start producing these frames at scale and helping the solar industry reap the benefits.
