RHS 50x25x2.5 SAISC · Weight & Dimensions

SAISC, 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 50x25 cal 13 (México) · Caño estructural 50x25 (Argentina)
