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 450x51 steel profile weighs 51.2 kg/m (34.41 lb/ft), has a depth of 450 mm (17.72 in), flange width 200 mm (7.87 in). Cross-sectional area: 6,515.3 mm². Moment of inertia Ix = 22,639.99 cm⁴, Iy = 1,267.56 cm⁴.
