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 300A (México) · Doble T ISHB 300A (Argentina / LATAM) · UB 300 (UK / Australia)
The ISHB 300A steel profile weighs 63.0 kg/m (42.34 lb/ft), has a depth of 300 mm (11.81 in), flange width 250 mm (9.84 in). Cross-sectional area: 7,920.7 mm². Moment of inertia Ix = 12,799.71 cm⁴, Iy = 2,762.35 cm⁴.
