RHS 120x60x4 · Weight & Dimensions

EN — Rectangular Hollow Section

Rectangular Hollow Sections (RHS) are tubular profiles with excellent torsional resistance and aesthetic appeal. Used for columns, trusses, and exposed structural elements.

Also known as: PTR 120x60 cal 8 (México) · Caño estructural 120x60 (Argentina)
