SHS 178x178x9.5 IMCA · Weight & Dimensions

IMCA, 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 178x178 (México) · Caño estructural 178x178 (Argentina)
