Epoxy Coated Rebar Coupler for Coastal Concrete Structures
Description
Epoxy coated rebar coupler are primarily used in environments with stringent corrosion resistance requirements, such as high-speed railways, cross-sea bridges, coastal regions in the Middle East, and maintenance projects in splash zones. Although epoxy-coated steel bars themselves possess outstanding corrosion resistance, traditional carbon steel connectors often prove inadequate, becoming the weak link in the overall corrosion protection system. Consequently, epoxy-coated straight thread rebar couplers, specifically engineered for coated steel bars, have emerged. This product ensures robust and reliable mechanical connections while delivering exceptional rust protection, effectively maintaining the durability and safety of engineering structures.

Product raw materials
Epoxy coated rebar coupler are manufactured from high-quality carbon structural steel (grade 45#). Using electrostatic spraying technology, epoxy resin powder is applied to the surface of standard rebar sleeves. This epoxy-coated reinforcement sleeve exhibits excellent corrosion resistance, though its bond strength with concrete is significantly reduced. It is suitable for reinforced concrete structures in industrial and civil buildings, general structures, roads, bridges, ports, and docks exposed to humid environments or corrosive media.
Used for manufacturing epoxy coated rebar coupler, their quality shall comply with the relevant current national standards. Their surface shall be smooth, free of sharp edges, burrs, or other defects that may affect coating quality, and contamination by oil, grease, paint, or similar substances shall be avoided.
