W 310 x 67,0 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 310 x 67,0 (México) · Doble T 310 x 67,0 (Argentina / LATAM) · UB 306 (UK / Australia)

The W 310 x 67,0 steel profile weighs 66.8 kg/m (44.89 lb/ft), has a depth of 306 mm (12.05 in), flange width 204 mm (8.03 in). Cross-sectional area: 8,502.742 mm². Moment of inertia Ix = 14,510.608 cm⁴, Iy = 2,068.503 cm⁴.
