HEA 450
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 450 steel profile weighs 140.0 kg/m (94.08 lb/ft), has a depth of 440 mm (17.32 in), flange width 300 mm (11.81 in). Cross-sectional area: 17,177 mm². Moment of inertia Ix = 61,389.81 cm⁴, Iy = 9,455.04 cm⁴.
