Epoxy Coated
Rebar
epoxy-coated rebar is produced using an electrostatic powder-spraying and high-temperature fusion process to form an epoxy protective coating on the surface of ordinary steel bars. This coating provides excellent chemical corrosion resistance and does not react with acids or alkalis. Moreover, the coating is highly impermeable, effectively delaying the contact between corrosive agents (such as water, oxygen, and chlorides) and the steel, thereby significantly extending its corrosion-resistant service life.

Efficiency
A recent study conducted by the University of Kansas for the Federal Highway Administration (FHWA) and the Kansas Department of Transportation evaluated the initial and life-cycle costs of epoxy-coated reinforcing steel. The study found that the initial cost of an epoxy-coated bridge deck was USD 196 per square yard, compared to USD 189 per square yard for an uncoated bridge deck. Therefore, the incremental cost was only USD 7 per square yard.
The research further showed that over a 75-year service life, using a 4% discount rate, the life-cycle cost of a bridge deck with epoxy-coated reinforcing steel was USD 237 per square yard, whereas the life-cycle cost of a deck with uncoated reinforcing steel was USD 444 per square yard. This represents a life-cycle cost savings of USD 207 per square yard when using epoxy-coated reinforcing steel. From this, it can be concluded that:
1. The return on investment (ROI) for epoxy-coated reinforcing steel reaches 2857% based on the formula {($207 - $7) / $7 × 100}.
2. Epoxy-coated reinforcing steel is a strong, cost-effective, and highly reliable investment for long-lasting and durable concrete structures.

Sustainability
The definition of sustainable development is: “development that meets the needs of the present without compromising the ability of future generations to meet their own needs, achieved through balancing social, economic, and environmental impacts.”
Epoxy-coated reinforcing steel is widely used and contributes to sustainability in the following ways:
1. Recycled Materials: Epoxy-coated reinforcing steel is produced from standard rebar products, which typically contain over 97% recycled content, primarily sourced from post-consumer materials. They are coated safely using environmentally friendly powders.
2. Embodied Energy: Epoxy-coated reinforcing steel requires lower embodied energy during manufacturing compared to other corrosion-resistant reinforcement options.
3. Durability: Epoxy-coated reinforcing steel has demonstrated over 40 years of proven field performance and significantly enhances the durability of concrete structures.
4. Cost: The cost of epoxy-coated reinforcing steel is lower than other corrosion-protection systems.
