RHS 300x150x7 Tecnometal · Weight & Dimensions

Tecnometal, cold-formed sections (Italy) · 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 300x150 (México) · Caño estructural 300x150 (Argentina)
