HEA 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 HEA 300 steel profile weighs 88.3 kg/m (59.34 lb/ft), has a depth of 290 mm (11.42 in), flange width 300 mm (11.81 in). Cross-sectional area: 10,627 mm². Moment of inertia Ix = 17,284.6 cm⁴, Iy = 6,301.34 cm⁴.
