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 ISJB 225 steel profile weighs 12.8 kg/m (8.60 lb/ft), has a depth of 225 mm (8.86 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,595.5 mm². Moment of inertia Ix = 1,274.6 cm⁴, Iy = 42.76 cm⁴.
