IS — 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: ISHB 300 (México) · Doble T ISHB 300 (Argentina / LATAM) · UB 300 (UK / Australia)
The ISHB 300 steel profile weighs 58.8 kg/m (39.51 lb/ft), has a depth of 300 mm (11.81 in), flange width 250 mm (9.84 in). Cross-sectional area: 7,418.9 mm². Moment of inertia Ix = 12,474.64 cm⁴, Iy = 2,761.44 cm⁴.
