EN — 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.

The UB 914x305x253 steel profile weighs 253.4 kg/m (170.28 lb/ft), has a depth of 918.4 mm (36.16 in), flange width 305.5 mm (12.03 in). Cross-sectional area: 31,969.9 mm². Moment of inertia Ix = 430,593.49 cm⁴, Iy = 13,295.48 cm⁴.
