Red Iron Steel Buildings Engineered for Strength & Precision
Red iron buildings are built using heavy I-beams that span the width of a structure. These I-beams are sealed in a protective layer of iron oxide primer and are engineered to support the structure without the need for internal columns. They’re strong, adaptable, and ready to take on large-scale agricultural jobs, aviation facilities, commercial projects, and anything that requires ample space for smooth operations.
ProSpan Steel Structures is a trusted national dealer of red iron metal buildings. Our structures are made with premium structural steel, customized to order, and engineered to tackle your toughest jobs.
