CES Cold Enforcement Splicing System
REBARLINK™ CES (Cold Enforcement Splicing System) is a high-performance parallel threaded mechanical rebar coupler system engineered for 100% bar-break performance, demanding reinforced concrete structures and controlled mechanical splice installation.
REBARLINK™ CES is a Cold Enforcement Splicing System using a parallel threaded mechanical rebar coupler configuration to connect reinforcing steel bars without relying on traditional lap splice length.
The REBARLINK™ CES Cold Enforcement Splicing System is a parallel threaded mechanical rebar coupler system developed for structural reinforced concrete applications requiring reliable mechanical load transfer, controlled installation and high connection performance.
What Is the CES Cold Enforcement Splicing System?
CES stands for Cold Enforcement Splicing System. REBARLINK™ uses the term Cold Enforcement to distinguish its CES system from conventional terminology used by other manufacturers for cold forged or cold upset rebar coupler systems. The CES system combines controlled bar-end preparation, precision thread processing and parallel threaded coupler assembly to create a controlled mechanical splice for reinforced concrete construction.
The system is designed to support high tensile performance, reliable thread engagement and controlled field installation. Application, performance and certification requirements should be verified against the applicable project specification and jurisdiction.

Coupler Manufacturing
Controlled manufacturing operations produce CES couplers according to specified geometry, material and dimensional requirements.
Precision Thread Processing
Precision machining creates the specified parallel thread geometry followed by dimensional verification of critical characteristics.
Go / No-Go Gauge Inspection
Calibrated gauges are used to verify functional thread engagement and applicable dimensional requirements.
Final Quality Approval
Final inspection and quality confirmation are completed before approved CES couplers are released for shipment.
Typical Applications
High-Rise Construction
Core walls, columns and high-density reinforcement zones requiring controlled mechanical splicing.
Infrastructure Projects
Bridges, tunnels, transportation structures and reinforced concrete infrastructure.
Energy & Industrial
Power plants, industrial facilities and critical reinforced concrete structures.
Precast & Modular Construction
Factory-manufactured reinforced concrete components and high-density reinforcement assemblies.
CES Rebar Coupler Installation Procedure
The CES mechanical splice system is designed for controlled field installation. Correct bar preparation, thread inspection and assembly procedures are essential for achieving the specified connection performance.
Rebar Cutting
Cut reinforcing bar ends square according to the required length and dimensional tolerance.
Cold Upsetting
Cold-forge the cut bar ends to enlarge the core diameter, providing an effective section for the subsequent thread and ensuring the joint is stronger than the bar.
Thread Processing
Cut precision parallel threads onto the cold-upset bar ends to match the internal thread of the coupler.
Thread Inspection
Verify thread quality and functional dimensions using calibrated inspection gauges.
Coupler Assembly
Assemble the coupler according to the applicable installation procedure and project requirements.
Parallel thread design supports controlled assembly and can help reduce reinforcement congestion associated with conventional lap splicing.

REQUEST DOCUMENTS →CES Cold Enforcement Splicing System FAQ
What is CES?
CES is the REBARLINK™ abbreviation for Cold Enforcement Splicing System, a parallel threaded mechanical rebar coupler system designed for reinforced concrete applications.
What does Cold Enforcement Splicing System mean?
Cold Enforcement is the terminology used by REBARLINK™ to identify its CES mechanical splicing system and distinguish the system from conventional cold forged terminology used by other manufacturers.
Is CES a parallel threaded rebar coupler?
Yes. CES uses a parallel threaded mechanical connection configuration designed for controlled thread engagement and mechanical load transfer.
Does CES provide 100% bar-break performance?
CES is engineered for 100% bar-break performance: under the applicable qualification and project test requirements, failure occurs in the reinforcing bar rather than at the mechanical splice.
How does REBARLINK™ control CES quality?
REBARLINK™ applies controlled material verification, heat treatment, coupler manufacturing, precision thread processing, Go / No-Go gauge inspection and final quality approval procedures.
What standards are relevant to CES?
Relevant standards may include ISO 15835, ACI 318 and other project-specific standards or specifications. Applicable certification and compliance documentation should be confirmed for each project.
What rebar sizes are available?
The current standard CES product range covers reinforcing bar sizes from Ø14 mm to Ø40 mm. Customized solutions can be evaluated for project-specific requirements.
Can CES replace traditional lap splicing?
Mechanical splicing can reduce reinforcement congestion and eliminate the additional steel length associated with conventional lap connections, subject to structural design and project requirements.
How is CES thread quality inspected?
CES thread quality and functional dimensions are verified using controlled Go / No-Go gauge inspection, and every critical thread characteristic is inspected before shipment.
What is the difference between CES and PPR rebar couplers?
CES uses controlled cold-enforcement bar-end preparation and precision parallel threading, while PPR uses automated rib-peeling and cold thread rolling. Both connect bars with a parallel thread, engineered for full-strength mechanical splicing.
