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 VS 250x21 steel profile weighs 20.7 kg/m (13.91 lb/ft), has a depth of 250 mm (9.84 in), flange width 120 mm (4.72 in). Cross-sectional area: 2,639.7 mm². Moment of inertia Ix = 2,775.04 cm⁴, Iy = 181.65 cm⁴.
