W 310 x 52,0 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 52,0 (México) · Doble T 310 x 52,0 (Argentina / LATAM) · UB 318 (UK / Australia)

The W 310 x 52,0 steel profile weighs 52.4 kg/m (35.19 lb/ft), has a depth of 318 mm (12.52 in), flange width 167 mm (6.57 in). Cross-sectional area: 6,679.898 mm². Moment of inertia Ix = 11,930.472 cm⁴, Iy = 1,025.892 cm⁴.
