RHS 30x25x2 Hiasa · Weight & Dimensions

Hiasa, 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 30x25 cal 15 (México) · Caño estructural 30x25 (Argentina)
