Anti-Corrosion Epoxy Coated Bolt Coupler

Our epoxy coated rebar coupler adopts cold upset forging parallel thread structure, made of 45# carbon steel. Surface treated with electrostatic high-temperature fused epoxy powder, perfectly matched with epoxy coated reinforcing bars. Sizes cover 12mm–40mm standard, custom large size 50/55/60mm available, compliant with ASTM, BS, EN, ACI 318, ISO 9001 and Chinese national standards.

ADVANTAGES

• No rebar cross-section loss, fully ductile elongation of steel bars

• Type 2 seismic grade, passes millions of cyclic fatigue tests

• Simple manual installation, no torque wrench required

• Complete raw material batch traceability, third-party certified

• Custom blue/green epoxy coating color per client demand

• Unified coupler fits standard & position splicing demands

APPLICATION

Marine & offshore projects: cross-sea bridges, seawater desalination plants, LNG facilities, splash zone piers. Civil infrastructure: metro tunnels, viaducts, high towers, expressway coastal sections. Heavy industry: nuclear power stations, underground stations with high groundwater, coastal reservoir & port structures.

Construction Application Methods

• Thread rebar ends with professional threading machine

• Screw epoxy coupler onto two coated rebars manually

• Visually check full thread engagement without welding

• Directly embed into concrete for permanent mechanical splicing

• For staggered connection, use adjustable & left-right thread couplers
