Fusion Bonded Epoxy Rebar (ASTM A775) first hit the construction market in , in a bridge project in Pennsylvania. From that moment on, epoxy coated rebar has become the standard for corrosion resistance in much of the United States.

During its first 30 years of use, standards for epoxy coated rebar evolved into what the industry experiences today &#; regulated by the Concrete Reinforcing Steel Institute (CRSI) to ensure quality standards are met day after day. Today&#;s epoxy coated rebar customers can expect extended service life over standard steel rebar, taking the foundation of the concrete structures forward to the next era.
Engineered to stand up to the challenging conditions of corrosive environments in the construction industry, epoxy coated rebar provides among the highest levels of corrosion resistance, at the lowest industry price on the market.
It is readily available throughout America from any of CMC&#;s six CRSI Certified Epoxy Coating Facilities. Our facilities are distributed throughout the country to provide customers with easy access to our full line of products and accessories. Availability and timing are further streamlined as our coating facilities are also fabricators.
Epoxy coated rebar is available in A615, from grades 40 to 100, and in A706 if welding or increased seismic protection are required. No matter the requirements for your project, our team is ready to help provide the right epoxy solution you need, when and where you need it.
Yaoan Wiremesh are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

For most of the s corrosion of bridge decks was not considered a significant concern. Properly designed and constructed bridges rarely experienced corrosion-related distress. This changed dramatically in the s when highway agencies began applying deicing salts to highways and bridges to keep roadways free of snow and ice. This &#;bare pavement&#; policy made roadways safer for the traveling public but resulted in a dramatic increase in deterioration due to corrosion on highways and bridges from chloride penetration. Between and annual usage of deicing salts in the United States rose from 1 million tons per year to more 12 million tons per year.
According to the Federal Highway Administration (FHWA), the cost of repairing or replacing structures deteriorated by corrosion is estimated to be more than $20 billion, and is said to be increasing at a rate of $500 million per year. In the General Accounting Office (GAO) noted that 32 states had more than 160,000 federal-aid system bridges that had moderate to very major corrosion problems.
In response the National Bureau of Standards (now the National Institute for Standards & Technology) initiated tests on various liquid and powdered coatings. These coatings were examined for their corrosion protective qualities, chemical and physical durability, and chloride permeability. Based on the testing, fusion-bonded epoxy coating applied to reinforcing steel was proposed as a way to improve the corrosion resistance of bridge decks.
Epoxy-coated reinforcing steel&#;was first used in a bridge in West Conshohocken, Pennsylvania in . Four spans of this bridge were constructed with&#;epoxy-coated steel reinforcing bars&#;&#;(rebar). It was reported in that at least 41 state transportation departments were using epoxy-coated reinforcing steel as the corrosion-protection system in their concrete decks. Every year over 600,000 ton of epoxy coated rebar is produced in the US and Canada and in , over 80,000 bridges and numerous buildings, wharfs and other structures contain&#;epoxy-coated steel reinforcing bars (rebar).
