SHS 115x115x7.1 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 115x115 (México) · Caño estructural 115x115 (Argentina)
