RHS 200x100x5 · Weight & Dimensions

EN — 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 200x100 cal 6 (México) · Caño estructural 200x100 (Argentina)
