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 450x70 steel profile weighs 70.1 kg/m (47.11 lb/ft), has a depth of 450 mm (17.72 in), flange width 250 mm (9.84 in). Cross-sectional area: 8,927.5 mm². Moment of inertia Ix = 33,945.56 cm⁴, Iy = 3,256.09 cm⁴.
