RHS 220x140x6.3 Iberian tables · Weight & Dimensions

Iberian tables, 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 220x140 cal 4 (México) · Caño estructural 220x140 (Argentina)
