HEB 280
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 HEB 280 steel profile weighs 103.0 kg/m (69.22 lb/ft), has a depth of 280 mm (11.02 in), flange width 280 mm (11.02 in). Cross-sectional area: 12,642 mm². Moment of inertia Ix = 18,596.6 cm⁴, Iy = 6,587.95 cm⁴.
