Why Use Stainless Steel Rebar?
Compared with Epoxy Coated Rebar
- Excellent corrosion resistance property
- No concerns about coating surface damage
- Life cycle cost advantage
Compared with Black Carbon Rebar
- Thinner concrete covering layer requirements
- Relaxed crack control specifications
- Lower carbon emissions
- Service life exceeding 250 years for concrete structures
Duplex 2304 Stainless Steel Reinforcement
2304 duplex stainless steel, also known as lean duplex stainless steel, provides equivalent chloride ion corrosion resistance to common austenitic stainless steel (316). It offers superior stress corrosion resistance and exceptional mechanical properties, combined with reduced dependence on nickel and molybdenum resources, making it a highly cost-effective solution. Due to its stable pricing and excellent weldability, it has achieved widespread adoption in concrete structures for global engineering projects, accounting for over 95% of global stainless steel rebar applications.
