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 200A steel profile weighs 21.1 kg/m (14.18 lb/ft), has a depth of 200 mm (7.87 in), flange width 100 mm (3.94 in). Cross-sectional area: 2,630.4 mm². Moment of inertia Ix = 1,766.12 cm⁴, Iy = 133.6 cm⁴.
