VS 300x34 · Weight & Dimensions

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 300x34 (México) · Doble T VS 300x34 (Argentina / LATAM) · UB 300 (UK / Australia)

The VS 300x34 steel profile weighs 34.3 kg/m (23.05 lb/ft), has a depth of 300 mm (11.81 in), flange width 160 mm (6.30 in). Cross-sectional area: 4,374.8 mm². Moment of inertia Ix = 7,294.22 cm⁴, Iy = 648.78 cm⁴.
