Structural Beams

Wide flange beams, plate girders, and box beams fabricated for structural framing and load-bearing applications.

145 manufacturers

Structural beams are the primary load-bearing members in steel-framed buildings, bridges, and industrial structures. Fabricated structural beams include standard wide flange shapes with welded connections, built-up plate girders for heavy loads and long spans, and specialty beams like castellated, cellular, and curved members. Structural beam fabrication begins with the structural engineer's design, translated into shop drawings by steel detailers. Fabricators then cut beams to length, drill or punch bolt holes, weld connection plates and stiffeners, and apply protective coatings. CNC beam lines automate many of these operations for efficiency and accuracy. AISC-certified fabricators are the standard for structural beam work, ensuring quality systems and procedures that meet building code requirements. When selecting a beam fabricator, consider their detailing coordination capabilities, coating facilities, and ability to deliver on your erection schedule.
