SHS 400x400x20 Tuboeuropa · Weight & Dimensions

Tuboeuropa, 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 400x400 (México) · Caño estructural 400x400 (Argentina)
