IPE 450 · Weight & Dimensions

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 450 (México) · Doble T IPE 450 (Argentina / LATAM) · UB 450 (UK / Australia)

The IPE 450 steel profile weighs 77.6 kg/m (52.15 lb/ft), has a depth of 450 mm (17.72 in), flange width 190 mm (7.48 in). Cross-sectional area: 9,503.5 mm². Moment of inertia Ix = 32,140.44 cm⁴, Iy = 1,671.94 cm⁴.
