UC 203x203x52 — Dimensions & Section Properties
EN — 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: UC 203x203x52 (México) · Doble T UC 203x203x52 (Argentina / LATAM) · UB 206.2 (UK / Australia)
