SHS 305x305x9.5 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 305x305 (México) · Caño estructural 305x305 (Argentina)
