RHS 120x100x3 Condesa · Weight & Dimensions

Condesa, cold-formed sections · 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 120x100 cal 11 (México) · Caño estructural 120x100 (Argentina)
