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 ISLB 325 steel profile weighs 43.1 kg/m (28.96 lb/ft), has a depth of 325 mm (12.80 in), flange width 165 mm (6.50 in). Cross-sectional area: 5,371.8 mm². Moment of inertia Ix = 9,696.71 cm⁴, Iy = 734.59 cm⁴.
