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 300x80 steel profile weighs 79.6 kg/m (53.49 lb/ft), has a depth of 300 mm (11.81 in), flange width 250 mm (9.84 in). Cross-sectional area: 10,144 mm². Moment of inertia Ix = 17,431.52 cm⁴, Iy = 4,167.81 cm⁴.
