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 UC 356x406x287 steel profile weighs 287.1 kg/m (192.93 lb/ft), has a depth of 393.6 mm (15.50 in), flange width 399 mm (15.71 in). Cross-sectional area: 36,372.6 mm². Moment of inertia Ix = 99,386.63 cm⁴, Iy = 38,672.9 cm⁴.
