Aluminum Formwork Systems > Rebar Couplers
Rebar Couplers
Rebar Couplers are an advanced solution designed to connect steel reinforcement bars without the need for traditional lap splicing. Ideal for high-rise buildings, infrastructure, and seismic-prone zones, these mechanical joints ensure superior strength, alignment, and performance. By using couplers, you can significantly reduce steel wastage, simplify construction, and speed up project timelines.
Types of Rebar Couplers
ABS PT Series
This is a Parallel Threaded Coupler. This type of coupler is used where the continuing TMT bar can be rotated.
ABS CF Series
This is a Cold Forged Parallel Threaded coupler for added strength. Rebar end is cold forged and then threaded.
ABS TP Series
This a Tapered Coupler. This type of coupler is used for high strength situations.
ABS TS Series
These are Transitional Couplers used to join TMT bars of different diameters. These are also known as reducers.
*Couplers can be customized as per the customers’ requirements upon bulk orders

Advantage of Aluminium Formwork
Reduce Steel Wastage
No overlaps mean more efficient use of reinforcement steel.
Faster Installation
Simplified installation process saves time on-site and accelerates project delivery.
High Structural Integrity
Provides a continuous load path, enhancing the strength and safety of the structure.
Ideal for Seismic Zones
Ensures secure bar connections in earthquake-prone areas where strength is critical.
Save Space in Congested Areas
Perfect for pile caps, columns, and beams where lap splicing is difficult.
Compatible with Prefab & Precast Structures
Ensures smoother integration in off-site or modular construction processes.
