SHSSteel
Square hollow sections (SHS) — cold-formed structural tube for columns, posts and architectural framing.
Square hollow section (SHS) is cold-formed structural steel tube with a square profile, valued for its symmetry, clean appearance and load capacity in columns, posts and architectural framing. We supply SHS across the full size range from 20×20 to 400×400, in wall thicknesses to suit, manufactured to AS/NZS 1163 in Grade C350L0 and C450L0. Available black, painted or galvanised with material certification.
