IPE 400
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 400 (México) · Doble T IPE 400 (Argentina / LATAM) · UB 400 (UK / Australia)
The IPE 400 steel profile weighs 66.3 kg/m (44.55 lb/ft), has a depth of 400 mm (15.75 in), flange width 180 mm (7.09 in). Cross-sectional area: 8,067.8 mm². Moment of inertia Ix = 21,876.47 cm⁴, Iy = 1,314.18 cm⁴.
