Description
Products Description
Epoxy-Coated Rebar (Epoxy-Coated Reinforcing Steel Bar), also known as Fusion Bonded Epoxy Coated Rebar (FBE Rebar), is a high-performance reinforcing material designed to provide superior corrosion resistance in concrete structures. Manufactured according to ASTM A775/A775M and ASTM A934/A934M standards, this product is available in a full range of diameters from #3 (10 mm) to #11 (36 mm), and lengths up to 12 m (40 ft). The green epoxy coating (commonly color code 607) acts as a protective barrier between the steel and corrosive environments such as chloride-contaminated concrete, coastal structures, bridges, highways, tunnels, and marine foundations.
Epoxy-Coated Rebar offers excellent adhesion, uniform coating thickness (typically 175–300 µm), and outstanding mechanical strength while maintaining the structural integrity of traditional carbon steel reinforcement. It can be supplied as straight bars, bent bars, dowels, or coils, making it ideal for a wide range of civil, commercial, and industrial construction applications.

Epoxy-coated rebar utilizes an electrostatic powder spraying and high-temperature sintering process to apply an epoxy resin protective coating to the surface of ordinary rebar. This coating offers excellent chemical resistance and is non-reactive with acids and alkalis. Furthermore, its impermeability delays contact between corrosive media (such as water, oxygen, and chlorides) and the rebar, significantly extending its corrosion life.
In short, the epoxy coating on the rebar provides protection and a barrier, making corrosion more difficult to develop.
We offer comprehensive corrosion-resistant rebar solutions. Epoxy-coated rebar is widely used for its excellent corrosion resistance.
Over 70% of our sales are dedicated to overseas mega-projects, including high-speed rail construction, cross-sea bridges, and splash zone maintenance, providing a one-stop service for these mega-projects.
China's epoxy coated steel bars adopt national standards GB/T 25826-2010 and Ministry of Housing and Construction standard JG/T 502-2016 (replacing JG 3042-1997). American standards are ASTM A775/A775M and ASTM A934/A934M, and British standard is BS ISO 14654. The whole life cycle analysis shows that the comprehensive cost of epoxy coated steel bar is very low. Epoxy coated reinforced concrete structures have a longer life than ordinary carbon steel concrete structures. The coating of the bar has anti-permeability, so it can delay the corrosion medium (such as water, oxygen, chloride, etc.) contact with the steel, so that its corrosion resistance life is greatly extended.

FAQ – Frequently Asked Questions
Q1: What is the main purpose of epoxy-coated rebar?
A1: It is designed to prevent corrosion and extend the life of reinforced concrete structures exposed to moisture, salt, or harsh chemical environments.
Q2: What's the difference between ASTM A775 and ASTM A934?
A2: ASTM A775 applies to bars coated after fabrication, while ASTM A934 applies to bars coated before bending or fabrication. A934 provides better coating integrity on complex shapes.
Q3: Can epoxy-coated rebar be cut or bent on-site?
A3: Bending after coating should be minimized. If required, use pre-heating and proper equipment to avoid coating damage. Touch-up epoxy may be used for repairs.
Q4: What coating thickness is recommended?
A4: The standard coating thickness is 175–300 µm, depending on the project and exposure conditions.
Q5: Is epoxy-coated rebar suitable for marine or coastal projects?
A5: Yes. It is specifically developed for saltwater and chloride-rich environments like piers, ports, and bridges.
application
1. Definition and composition
Epoxy coated steel bars are made by coating a layer of epoxy powder coating on the surface of steel bars. Through a specific process, it is tightly bonded to the surface of the steel bars to form a dense anti-corrosion layer. This coating can effectively isolate the steel bars from the surrounding environment, thereby preventing the steel bars from corroding.
2. Manufacturing process
The manufacturing process of epoxy coated steel bars mainly includes the steps of steel bar surface pretreatment, epoxy powder coating preparation and coating, curing and cooling. Among them, steel bar surface pretreatment is the key link, and it is necessary to thoroughly remove impurities such as oil and rust on the surface of the steel bars to ensure a good combination of the coating and the steel bars. Electrostatic spraying is usually used during coating to make the epoxy powder evenly adhere to the surface of the steel bars. The curing process needs to be carried out at high temperature to melt the epoxy powder and level it on the surface of the steel bars, and finally form a solid anti-corrosion layer.
3. Performance characteristics
Excellent anti-corrosion performance: Epoxy coating has extremely high corrosion resistance, which can effectively prevent the corrosion of steel bars in harsh environments and extend the service life of steel bars.
Good adhesion: The epoxy coating is tightly bonded to the surface of the steel bar, not easy to fall off, and can maintain a long-term anti-corrosion effect.
Convenient construction: The construction process of epoxy coated steel bars is relatively simple and easy to operate, which can greatly improve the construction efficiency.
Environmental performance: Epoxy coating materials are non-toxic, non-polluting, meet environmental protection requirements, and are harmless to the human body and the environment.
4. Application fields
Epoxy coated steel bars are widely used in various occasions where steel bar anti-corrosion is required, such as bridges, tunnels, highways, water conservancy projects, seaports and other infrastructure construction. Especially in environments containing chloride ions, such as coastal areas or salt lake areas, the anti-corrosion performance of epoxy coated steel bars is more prominent, which can effectively prevent structural damage caused by corrosion of steel bars.
