Why Use Stainless Steel Rebar?
Comparison with Epoxy Coated Rebar:
- Excellent corrosion resistance property
- No concerns about coating surface damage
- Life cycle cost advantage
Comparison with Black Carbon Rebar:
- Thinner concrete covering layer required
- Relaxed crack control requirements
- 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 the same resistance to chloride ion corrosion as common austenitic stainless steel (316). It excels in stress corrosion resistance and offers outstanding mechanical properties, coupled with a lower reliance on nickel and molybdenum resources, making it a highly cost-effective choice. Thanks to its relatively stable pricing and excellent weldability, it has found widespread use in concrete structures for global engineering projects, accounting for over 95% of the global stainless steel rebar application proportion.
