RHS 304.8x203.2x6.35 CISC · Weight & Dimensions

CISC, 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 304.8x203.2 cal 3 (México) · Caño estructural 304.8x203.2 (Argentina)
