HEA 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.
Also known as: HEA 280 (México) · Doble T HEA 280 (Argentina / LATAM) · UB 270 (UK / Australia)
The HEA 280 steel profile weighs 76.4 kg/m (51.34 lb/ft), has a depth of 270 mm (10.63 in), flange width 280 mm (11.02 in). Cross-sectional area: 9,232 mm². Moment of inertia Ix = 12,999.62 cm⁴, Iy = 4,757.31 cm⁴.
