RHS 180x100x3.6 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 180x100 (México) · Caño estructural 180x100 (Argentina)
