Transition Rebar Coupler
Key Features
✅ Connects rebars of two different diameters,
ensuring reliable continuity in size-transition zones
✅ Matches or exceeds the tensile strength of the
smaller diameter bar for maximum structural integrity
✅ Compact design minimizes reinforcement congestion
and simplifies rebar layout
✅ Compatible with parallel threaded, cold-forged bar
ends for universal adaptability
✅ Treated with corrosion-resistant coating for
long-term durability in exposed conditions
Technical Specifications
✅ Rebar Size Range: 16mm to 40mm (any two
combinations)
✅ Material: High-strength carbon or alloy steel
✅ Thread Type: Parallel thread with 60° angle
✅ Standard Configurations: Left-to-Right and
Right-to-Right
✅ Surface Finish: Zinc-coated or custom
anti-corrosive finish
Applications
✅ High-rise structures for connecting slabs and
columns of differing bar diameters
✅ Infrastructure like flyovers, metro rail, and
bridges with stepped reinforcement zones
✅ Retrofit and extension works where existing bars
need size adaptation
✅ Pile caps and footings where load transitions
between columns and foundations occur
✅ Precast construction to connect on-site and
off-site cast elements with varying bar sizes
Installation Process
✅ Bar ends are cut, optionally cold-forged, and then
threaded using a rebar threading machine
✅ Select a transition coupler matching the two bar
sizes involved
✅ One side of the coupler is connected to the larger
diameter bar, then the smaller bar is threaded into the other end to create a
secure splice
Advantages
✅ Eliminates the need for lap splicing, reducing
steel usage and rebar congestion
✅ Quick and secure installation on-site with minimal
tools
✅ Ensures proper axial load transfer even with
dissimilar bar diameters
✅ No welding required, increasing jobsite safety and
reducing labor costs
✅ Custom sizes available to meet project-specific
requirements
Quality Assurance
✅ Each Transition Coupler is tested for thread
accuracy, tensile strength, and dimensional compliance
✅ Products are marked with Unique Identification
Numbers (UIN) for batch traceability
✅ Manufactured to meet international safety and
construction standards
