HEB 450
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 450 (México) · Doble T HEB 450 (Argentina / LATAM) · UB 450 (UK / Australia)
The HEB 450 steel profile weighs 171.0 kg/m (114.91 lb/ft), has a depth of 450 mm (17.72 in), flange width 300 mm (11.81 in). Cross-sectional area: 21,172 mm². Moment of inertia Ix = 77,555.75 cm⁴, Iy = 11,709.1 cm⁴.
