HEA 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 HEA 400 steel profile weighs 125.0 kg/m (84.00 lb/ft), has a depth of 390 mm (15.35 in), flange width 300 mm (11.81 in). Cross-sectional area: 15,272 mm². Moment of inertia Ix = 43,259.95 cm⁴, Iy = 8,553.9 cm⁴.
