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.
The ISWB 250 steel profile weighs 40.9 kg/m (27.48 lb/ft), has a depth of 250 mm (9.84 in), flange width 200 mm (7.87 in). Cross-sectional area: 5,154.4 mm². Moment of inertia Ix = 5,926.92 cm⁴, Iy = 1,200.58 cm⁴.
