SHS 135x135x7.1 Açotubo · Weight & Dimensions

Açotubo, cold-formed sections · Square Hollow Section

Square Hollow Sections (SHS) are tubular profiles with equal sides, ideal for columns and compression members due to their uniform buckling resistance in all directions.

Also known as: PTR 135x135 (México) · Caño estructural 135x135 (Argentina)
