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 250A (México) · Doble T ISHB 250A (Argentina / LATAM) · UB 250 (UK / Australia)
The ISHB 250A steel profile weighs 54.7 kg/m (36.76 lb/ft), has a depth of 250 mm (9.84 in), flange width 250 mm (9.84 in). Cross-sectional area: 6,879.3 mm². Moment of inertia Ix = 7,904.52 cm⁴, Iy = 2,527.35 cm⁴.
