Vulcraft/Verco Group is North America’s largest producer of steel joists and girders. Our steel joists and girders are produced and marketed through eight Vulcraft facilities that obtain the majority of their steel from Nucor bar mills.

Every Vulcraft joist is engineered to the customer’s exact specifications. In addition, we ensure the highest level of quality and structural integrity in our steel joists and girders through a mechanical testing program, including full-scale load tests, at every Vulcraft facility.
