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 350x28 steel profile weighs 28.4 kg/m (19.08 lb/ft), has a depth of 350 mm (13.78 in), flange width 160 mm (6.30 in). Cross-sectional area: 3,618.7 mm². Moment of inertia Ix = 7,474.77 cm⁴, Iy = 430.38 cm⁴.
