HEM 300
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 300 steel profile weighs 238.0 kg/m (159.94 lb/ft), has a depth of 340 mm (13.39 in), flange width 310 mm (12.20 in). Cross-sectional area: 29,682 mm². Moment of inertia Ix = 58,222.11 cm⁴, Iy = 19,384.37 cm⁴.
