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 550 steel profile weighs 166.0 kg/m (111.55 lb/ft), has a depth of 540 mm (21.26 in), flange width 300 mm (11.81 in). Cross-sectional area: 20,550 mm². Moment of inertia Ix = 108,327.06 cm⁴, Iy = 10,808.01 cm⁴.
