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 350 steel profile weighs 49.5 kg/m (33.26 lb/ft), has a depth of 350 mm (13.78 in), flange width 165 mm (6.50 in). Cross-sectional area: 6,183.3 mm². Moment of inertia Ix = 12,947.09 cm⁴, Iy = 854.61 cm⁴.
