ISWB 450

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 450 steel profile weighs 79.4 kg/m (53.36 lb/ft), has a depth of 450 mm (17.72 in), flange width 200 mm (7.87 in). Cross-sectional area: 10,016.6 mm². Moment of inertia Ix = 34,746.94 cm⁴, Iy = 2,056.05 cm⁴.
