W 360 x 51,0 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 360 x 51,0 (México) · Doble T 360 x 51,0 (Argentina / LATAM) · UB 355 (UK / Australia)

The W 360 x 51,0 steel profile weighs 50.6 kg/m (34.02 lb/ft), has a depth of 355 mm (13.98 in), flange width 171 mm (6.73 in). Cross-sectional area: 6,442.001 mm². Moment of inertia Ix = 14,121.773 cm⁴, Iy = 968.062 cm⁴.
