RHS 70x60x5.6 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 70x60 (México) · Caño estructural 70x60 (Argentina)
