CES Cold Enforcement Splicing System — Parallel Threaded Rebar Coupler
REBARLINK™ CES (Cold Enforcement Splicing System) is a parallel threaded mechanical rebar coupler system engineered for full bar-break performance under applicable qualification and project test requirements, demanding reinforced concrete structures and controlled mechanical splice installation.

REBARLINK™ CES is a parallel threaded rebar coupler system for mechanical rebar splicing. It uses controlled cold bar-end preparation and precision parallel threading to connect reinforcing bars in reinforced concrete structures, with the system engineered for full bar-break performance under applicable qualification and project test requirements.
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 intended for applications where mechanical load transfer, reinforcement continuity and controlled installation are important project considerations.
Application, performance, certification and testing requirements should always be verified against the applicable product specification, structural design requirements and jurisdiction.

CES Rebar Coupler Performance & Engineering Characteristics
Full Bar-Break Performance
CES is engineered around a full bar-break performance principle. Under the applicable qualification and project test requirements, the intended performance is for failure to occur in the reinforcing bar rather than at the mechanical splice.
Cold Enforcement Bar-End Preparation
Controlled bar-end preparation supports the required geometry and effective section for subsequent precision thread processing.
Parallel Thread Connection
Precision parallel threads provide controlled mechanical engagement and repeatable assembly characteristics.
Structural Applications
Designed for demanding reinforced concrete applications including high-rise, infrastructure, industrial and other critical structures, subject to project design requirements.
Reduced Rebar Congestion
Mechanical splicing can reduce the reinforcement overlap associated with conventional lap connections and may help improve reinforcement arrangement where permitted by structural design requirements.
Controlled Installation
Controlled assembly and inspection procedures provide construction teams with a repeatable mechanical splice installation process.

FULL BAR-BREAK PERFORMANCE
REBARLINK™ CES is engineered around a full bar-break performance principle. Under the applicable qualification and project test requirements, the mechanical splice is designed so that the reinforcing bar is intended to fail before the mechanical splice.

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 around a full bar-break performance principle. Under the applicable qualification and project test requirements, the intended performance is for failure to occur 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 critical thread characteristics and functional dimensions are verified using controlled Go / No-Go gauge inspection and applicable production quality-control procedures.
What is the difference between CES and PPR rebar couplers?
CES uses controlled cold bar-end preparation and precision parallel threading, while PPR uses automated rib peeling and cold thread rolling. Both systems use a parallel threaded mechanical connection and are engineered for full-strength mechanical splicing under applicable qualification requirements.
What is a parallel threaded rebar coupler?
A parallel threaded rebar coupler is a mechanical splice fitting that connects reinforcing bars using matching parallel threads rather than relying on conventional lap splice length.
What is the difference between a mechanical splice and a lap splice?
A mechanical splice transfers reinforcing bar forces through a mechanical connection, while a conventional lap splice transfers forces through the overlapping length of reinforcing bars and surrounding concrete. Selection should follow structural design and applicable project requirements.
When should a mechanical rebar splice be used?
Mechanical rebar splices may be considered where reinforcement congestion, bar continuity, construction sequence, lap-length limitations or project-specific structural requirements make mechanical connection advantageous.
