How does Epoxy-Coated Steel Reinforcing Bar compare with stainless steel reinforcing bar?
Stainless-steel bars cost up to five times as much as black bars and may increase the total structural cost by 10 percent or more. • Additional funding often is not available for these products. • Stainless-steel bars use materials from hard-rock mining operations, while Epoxy-Coated Steel Reinforcing Bar uses scrap steel. • Not all stainless steels have demonstrated good corrosion performance in concrete as it depends on the grade of stainless. • Care must be taken to ensure that stainless-steel bars are not contaminated with black bar.
