IPE 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: IPE 550 (México) · Doble T IPE 550 (Argentina / LATAM) · UB 550 (UK / Australia)
The IPE 550 steel profile weighs 106.0 kg/m (71.23 lb/ft), has a depth of 550 mm (21.65 in), flange width 210 mm (8.27 in). Cross-sectional area: 12,947.2 mm². Moment of inertia Ix = 63,964.65 cm⁴, Iy = 2,660.7 cm⁴.
