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 450x71 steel profile weighs 70.9 kg/m (47.64 lb/ft), has a depth of 450 mm (17.72 in), flange width 200 mm (7.87 in). Cross-sectional area: 9,033.4 mm². Moment of inertia Ix = 33,984.93 cm⁴, Iy = 2,134.2 cm⁴.
