W 200 x 12,0 KS · Weight & Dimensions

KS, 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 200 x 12,0 (México) · Doble T 200 x 12,0 (Argentina / LATAM) · UB 200 (UK / Australia)
