W 260 x 89,5 SAISC · Weight & Dimensions

SAISC, hot-rolled 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: IPR 260 x 89,5 (México) · Doble T 260 x 89,5 (Argentina / LATAM) · UB 260.4 (UK / Australia)
