BR — 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 CVS 350x128 steel profile weighs 127.6 kg/m (85.75 lb/ft), has a depth of 350 mm (13.78 in), flange width 250 mm (9.84 in). Cross-sectional area: 16,250 mm². Moment of inertia Ix = 35,885.42 cm⁴, Iy = 6,515.3 cm⁴.
