RHS 80x60x3.2 Acindar · Weight & Dimensions

Acindar, 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 80x60 cal 11 (México) · Caño estructural 80x60 (Argentina)
