W 100 x 19,0 CISC · Weight & Dimensions

CISC, hot-rolled sections · 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: IPR 100 x 19,0 (México) · Doble T 100 x 19,0 (Argentina / LATAM) · UB 106 (UK / Australia)

The W 100 x 19,0 steel profile weighs 19.5 kg/m (13.08 lb/ft), has a depth of 106 mm (4.17 in), flange width 103 mm (4.06 in). Cross-sectional area: 2,471.343 mm². Moment of inertia Ix = 475.899 cm⁴, Iy = 160.608 cm⁴.
