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 686x254x152 steel profile weighs 152.4 kg/m (102.41 lb/ft), has a depth of 687.5 mm (27.07 in), flange width 254.5 mm (10.02 in). Cross-sectional area: 19,209.6 mm². Moment of inertia Ix = 148,332.24 cm⁴, Iy = 5,781.78 cm⁴.
