HEB 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: HEB 400 (México) · Doble T HEB 400 (Argentina / LATAM) · UB 400 (UK / Australia)
The HEB 400 steel profile weighs 155.0 kg/m (104.16 lb/ft), has a depth of 400 mm (15.75 in), flange width 300 mm (11.81 in). Cross-sectional area: 19,152 mm². Moment of inertia Ix = 55,871.08 cm⁴, Iy = 10,807.22 cm⁴.
