RHS 90x30x1.9 Tecnometal · Weight & Dimensions

Tecnometal, cold-formed sections (Brazil) · 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 90x30 cal 15 (México) · Caño estructural 90x30 (Argentina)
