HEB 550
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: HEB 550 (México) · Doble T HEB 550 (Argentina / LATAM) · UB 550 (UK / Australia)
The HEB 550 steel profile weighs 199.0 kg/m (133.73 lb/ft), has a depth of 550 mm (21.65 in), flange width 300 mm (11.81 in). Cross-sectional area: 24,780 mm². Moment of inertia Ix = 133,085.72 cm⁴, Iy = 13,063.84 cm⁴.
