VS 400x39 · 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 400x39 (México) · Doble T VS 400x39 (Argentina / LATAM) · UB 400 (UK / Australia)

The VS 400x39 steel profile weighs 39.4 kg/m (26.48 lb/ft), has a depth of 400 mm (15.75 in), flange width 200 mm (7.87 in). Cross-sectional area: 5,024 mm². Moment of inertia Ix = 14,536.16 cm⁴, Iy = 1,067.01 cm⁴.
