VS 1200x221

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 1200x221 steel profile weighs 220.9 kg/m (148.44 lb/ft), has a depth of 1200 mm (47.24 in), flange width 450 mm (17.72 in). Cross-sectional area: 28,139 mm². Moment of inertia Ix = 720,522.97 cm⁴, Iy = 28,864.55 cm⁴.
