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 250 (México) · Doble T ISHB 250 (Argentina / LATAM) · UB 250 (UK / Australia)
The ISHB 250 steel profile weighs 51.0 kg/m (34.27 lb/ft), has a depth of 250 mm (9.84 in), flange width 250 mm (9.84 in). Cross-sectional area: 6,441.1 mm². Moment of inertia Ix = 7,710.37 cm⁴, Iy = 2,526.67 cm⁴.
