RHS 60x40x4.4 Açotubo · Weight & Dimensions

Açotubo, 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 60x40 (México) · Caño estructural 60x40 (Argentina)
