RHS 50.8x25.4x2.54 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 50.8x25.4 cal 13 (México) · Caño estructural 50.8x25.4 (Argentina)
