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 300x66 steel profile weighs 66.3 kg/m (44.55 lb/ft), has a depth of 300 mm (11.81 in), flange width 250 mm (9.84 in). Cross-sectional area: 8,450 mm². Moment of inertia Ix = 14,309.64 cm⁴, Iy = 3,256.38 cm⁴.
