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.

Also known as: VS 300x31 (México) · Doble T VS 300x31 (Argentina / LATAM) · UB 300 (UK / Australia)

The VS 300x31 steel profile weighs 30.7 kg/m (20.63 lb/ft), has a depth of 300 mm (11.81 in), flange width 160 mm (6.30 in). Cross-sectional area: 3,909 mm². Moment of inertia Ix = 6,364.97 cm⁴, Iy = 546.39 cm⁴.
