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 350 steel profile weighs 56.9 kg/m (38.24 lb/ft), has a depth of 350 mm (13.78 in), flange width 200 mm (7.87 in). Cross-sectional area: 7,177.6 mm². Moment of inertia Ix = 15,410.37 cm⁴, Iy = 1,521.4 cm⁴.
