I 775x180x9.5x12.7 IMCA · Weight & Dimensions

IMCA, welded sections · Wide Flange (I-beam)

Wide flange beams (W shapes / I-beams) are the most common structural steel profile used in building construction. They are used for beams, columns, and girders in steel-framed buildings and bridges. Designed per AISC 360, Eurocode 3, and NBR 8800.

Also known as: I 775x180x9.5x12.7 (México) · Doble T I 775x180x9.5x12.7 (Argentina / LATAM) · UB 775 (UK / Australia)
