W 530 x 85,0 Gerdau · Weight & Dimensions

Gerdau · 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 530 x 85,0 (México) · Doble T 530 x 85,0 (Argentina / LATAM) · UB 535 (UK / Australia)

The W 530 x 85,0 steel profile weighs 85.0 kg/m (57.12 lb/ft), has a depth of 535 mm (21.06 in), flange width 166 mm (6.54 in). Cross-sectional area: 10,772.211 mm². Moment of inertia Ix = 48,451.085 cm⁴, Iy = 1,263.323 cm⁴.
