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 356x171x57 steel profile weighs 57.0 kg/m (38.30 lb/ft), has a depth of 358 mm (14.09 in), flange width 172.2 mm (6.78 in). Cross-sectional area: 7,166.4 mm². Moment of inertia Ix = 15,798.89 cm⁴, Iy = 1,107.82 cm⁴.
