W 250 x 39,0 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 39,0 (México) · Doble T 250 x 39,0 (Argentina / LATAM) · UB 262 (UK / Australia)

The W 250 x 39,0 steel profile weighs 38.6 kg/m (25.95 lb/ft), has a depth of 262 mm (10.31 in), flange width 147 mm (5.79 in). Cross-sectional area: 4,929.098 mm². Moment of inertia Ix = 6,014.473 cm⁴, Iy = 593.68 cm⁴.
