RHS 180x60x6 GOST · Weight & Dimensions

GOST, 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 180x60 cal 4 (México) · Caño estructural 180x60 (Argentina)
