HEM 400
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 HEM 400 steel profile weighs 256.0 kg/m (172.03 lb/ft), has a depth of 432 mm (17.01 in), flange width 307 mm (12.09 in). Cross-sectional area: 31,952 mm². Moment of inertia Ix = 102,309.65 cm⁴, Iy = 19,316.79 cm⁴.
