RHS 30x20x1.5 Cintac · Weight & Dimensions

Cintac, 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 30x20 cal 16 (México) · Caño estructural 30x20 (Argentina)
