W 250 x 28,0 CISC · Weight & Dimensions

CISC, 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 250 x 28,0 (México) · Doble T 250 x 28,0 (Argentina / LATAM) · UB 260 (UK / Australia)

The W 250 x 28,0 steel profile weighs 28.5 kg/m (19.15 lb/ft), has a depth of 260 mm (10.24 in), flange width 102 mm (4.02 in). Cross-sectional area: 3,630.938 mm². Moment of inertia Ix = 4,003.265 cm⁴, Iy = 177.541 cm⁴.
