Epoxy Coated Rebar is manufactured by applying a durable epoxy coating to deformed steel reinforcement bars, providing outstanding corrosion resistance and extended service life in aggressive environments. It is designed for reinforced concrete structures exposed to moisture, chemicals, and chloride-rich conditions.
Widely used in bridges, marine structures, highways, parking facilities, and coastal construction projects requiring long-term corrosion protection and structural durability.
Epoxy coated rebar (fusion-bonded epoxy coated steel reinforcing bar, FBE rebar, corrosion-resistant rebar, ASTM A775 steel rebar, and green coated rebar) serves as a vital structural reinforcement material across civil infrastructure, marine port construction, bridge deck overlays, and coastal concrete foundations. Manufactured by applying a protective thermosetting epoxy powder coating via electrostatic spray onto shot-blasted, pre-heated steel rebar, epoxy coated rebar provides an impermeable dielectric barrier that isolates steel from corrosive moisture, airborne chlorides, deicing salts, and harsh chemical environments.
At XQJ Metal, we manufacture and export premium-grade epoxy coated rebar strictly adhering to major international engineering standards, including ASTM A775 / A775M (standard specification for epoxy-coated steel reinforcing bars), ASTM A934 (pre-fabricated epoxy coating), ISO 14654, and BS 4449 specifications. Our state-of-the-art coating lines supply bar sizes from #3 to #11 (10mm to 40mm nominal diameter), steel yield grades including Grade 40, Grade 60 (420 MPa), and Grade 75 (520 MPa), standard stock lengths of 20ft, 40ft (6m, 12m), and custom cut-and-bend configurations.

Evaluating corrosion protection mechanisms helps infrastructure authorities and civil engineering consultants optimize structural longevity against lifetime maintenance costs:
Bridge engineers, port contractors, and DOT procurement agencies specify our epoxy coated rebar for critical concrete structures due to several superior performance features:
Our heavy-duty epoxy coated rebar reinforces critical concrete infrastructure exposed to aggressive corrosive environments worldwide:
To guarantee complete corrosion protection and zero coating defects during ocean transit, XQJ Metal enforces strict Quality Assurance (QA) protocols on every epoxy coated rebar shipment:
Q1: What is the recommended epoxy coating thickness for ASTM A775 epoxy coated rebar?
A: According to ASTM A775 / A775M standards, the specified coating thickness after curing should be between 175 and 300 µm (7 to 12 mils) for at least 90% of all recorded measurement points on the rebar.
Q2: How should cut ends and damaged handling areas be treated on-site for epoxy coated rebar?
A: Any field-cut bar ends, sheared edges, or minor handling scratches must be thoroughly cleaned and coated with a compatible two-part liquid epoxy touch-up compound approved under ASTM A775 prior to concrete placement.

Our materials support a wide range of construction and infrastructure projects
Epoxy coated rebar is protected by a bonded epoxy coating that helps isolate the steel from moisture, chlorides, and other corrosive substances, while black steel rebar has no protective coating. Epoxy coated rebar is commonly specified for structures exposed to aggressive environments where enhanced corrosion protection is required.
The epoxy coating acts as a protective barrier that helps reduce corrosion caused by moisture and chloride penetration. By protecting the reinforcing steel, it contributes to improved durability and reduced maintenance requirements over the service life of the structure.
Epoxy coated rebar is commonly specified for bridges, marine structures, parking garages, coastal infrastructure, wastewater facilities, and other reinforced concrete projects exposed to corrosive environments where long-term durability is a primary design consideration.
It offers excellent resistance to seawater corrosion and maintains strength in humid and salt-rich conditions.
No. Strength is achieved through strain hardening rather than heat treatment.
Yes. It provides excellent weldability for structural fabrication.
Yes, it is commonly applied in tanks and pressure equipment.
Yes. It provides higher strength compared with most non-heat-treated aluminum alloys.
Yes. Thickness, width and temper can be adjusted based on project demand.
