For more than 60 years, A&S; Building Systems was a regional leader in the design and fabrication of prefabricated metal buildings for manufacturing, commercial, educational, religious, aviation and recreational facilities throughout the United States.


In 2018, the A&S; brand became a part of the Cornerstone Building Brands family—the #1 manufacturer of exterior building products in North America. In addition to A&S;’s core product, framing systems, customers now had access to expanded envelope solutions across both the commercial and residential industries.


In March 2021, the A&S; name was retired and today our customers are serviced by its sister engineered building systems brands under the Cornerstone Building Brands umbrella. We give a nod to A&S;’s history and long-standing accomplishments, knowing the brand’s commitment to its builders and core values—safety, innovation, integrity and teamwork—continues.


Today, Cornerstone Buildings Brands services the Engineered Building Systems market under four go-to-market brands in the United States (Ceco Building Systems, Heritage Building Systems, Metallic Building Systems, and Star Building Systems) and as Robertson Building Systems in Canada. Across the enterprise, we are relentlessly committed to our customers and to creating great building solutions that enable communities to grow and thrive. We believe every building we create, and every part of that building, positively contributes to communities where people live, work and play.
