Protection Matters
Corrosion protection is one of the earliest material decisions made on a project, but its impact can last for decades. Exposure conditions, service-life requirements, constructability considerations and long-term maintenance expectations all influence how reinforced concrete structures perform over time.
Because every project faces different conditions, there is no single corrosion-resistant rebar solution that is right for every application.
CMC is the only U.S. manufacturer offering a broad portfolio of corrosion-resistant rebar solutions. Through epoxy-coated, galvanized and chromium-alloy technologies, CMC helps project teams evaluate multiple approaches to corrosion protection and select the level of protection that aligns with project requirements.
Why a Portfolio Approach Matters
The right corrosion-resistant rebar solution depends on the demands of the project.
Some projects prioritize proven familiarity and broad specification acceptance. Others require enhanced protection in aggressive chloride environments. Some owners are evaluating design life, maintenance impacts and long-term durability requirements decades into the future.
The advantage of a portfolio approach is the ability to evaluate options based on project needs rather than product limitations. CMC brings multiple corrosion protection technologies together through a single source, helping owners, engineers, fabricators and contractors make informed decisions with confidence.
Technical Expertise Behind Every Solution
Corrosion-resistant rebar selection is more than a product choice. It is an engineering decision.
CMC supports project teams with technical resources that include professional engineers and engineering PhDs who help evaluate corrosion protection strategies, exposure conditions, constructability considerations and service-life objectives. Combined with a broad portfolio of solutions, this expertise helps customers understand the tradeoffs between technologies and identify the right level of protection for their project.

Epoxy-Coated Rebar
Fusion Bonded Epoxy Rebar (ASTM A775) has been used in transportation and infrastructure applications for more than five decades and remains one of the most widely specified corrosion-resistant reinforcement solutions in North America. Epoxy-coated rebar utilizes a protective barrier coating to help isolate reinforcing steel from corrosive environments while providing an economical approach to corrosion resistance.

GalvaBar®
GalvaBar® is a continuously galvanized reinforcing steel solution that combines the corrosion protection of zinc with fabrication flexibility. Manufactured to ASTM A1094 standards, GalvaBar can be bent and fabricated after galvanizing without concerns about peeling or flaking coatings. It is commonly used in bridge, highway, precast and cast-in-place concrete applications.

ChromX®
ChromX® is a chromium-alloy reinforcing steel solution that incorporates corrosion resistance into the steel itself rather than relying on a coating. Utilizing a proprietary steel microstructure, ChromX provides corrosion resistance and high-strength performance while supporting conventional fabrication and installation practices. It has been used in bridges, roads, dams, tunnels, building structures, parking garages and marine applications.
