Stainless steel square tube
Stainless steel as a material effectively decreases life cycle costs and offers excellent corrosion resistance as well as freedom from maintenance needs. The durable and sustainable, 100 % recyclable material is a perfect match for various industries needing light-weight, high-strength solutions.
Made of Austenitic, Duplex and Lean Duplex steel grades, stainless steel square tube are built for challenging conditions. For the building and construction industry, their fire resistance properties make them an attractive choice for structures – without a need for coating. In highly corrosive environments, Duplex and Lean Duplex beams and profiles provide superior general corrosion resistance, pitting resistance and intergranular corrosion resistance.
