Good quality manufactured epoxy-coated steel reinforcement bars have a significant role in delaying the rate of corrosion. The more delicate the coating, the lesser is the corrosion resistance. This is one reason where stainless steel scores more over epoxy coated rebar. Stainless steel provides excellent corrosion resistance and guaranteed durability, unlike epoxy-coated rebars. But stainless steel is eight times more expensive than epoxy-coated bars. So, a choice is made depending on the durability required and the budget of the project.
