W 530 x 74,0 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 530 x 74,0 (México) · Doble T 530 x 74,0 (Argentina / LATAM) · UB 529 (UK / Australia)

The W 530 x 74,0 steel profile weighs 74.7 kg/m (50.22 lb/ft), has a depth of 529 mm (20.83 in), flange width 166 mm (6.54 in). Cross-sectional area: 9,527.731 mm². Moment of inertia Ix = 41,098.07 cm⁴, Iy = 1,041.615 cm⁴.
