RHS 100x75x3 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 100x75 cal 11 (México) · Caño estructural 100x75 (Argentina)
