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 550x75 steel profile weighs 75.0 kg/m (50.40 lb/ft), has a depth of 550 mm (21.65 in), flange width 250 mm (9.84 in). Cross-sectional area: 9,557.5 mm². Moment of inertia Ix = 52,746.65 cm⁴, Iy = 3,256.3 cm⁴.
