HEB 300
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 300 (México) · Doble T HEB 300 (Argentina / LATAM) · UB 300 (UK / Australia)
The HEB 300 steel profile weighs 117.0 kg/m (78.62 lb/ft), has a depth of 300 mm (11.81 in), flange width 300 mm (11.81 in). Cross-sectional area: 14,282 mm². Moment of inertia Ix = 24,186.78 cm⁴, Iy = 8,552.91 cm⁴.
