Upset parallel thread reinforcement coupler with high-strength thread on the inner side (Mechanical Reinforcement Coupler). In this method a screw thread is cut on one side of the rebar at the length of half of the Rebar Coupler and threads are put under protection with plastic accessories. A thread is cut on the rebar on the opposite side at the length of the coupler and assembled on the reinforcement.                   

These rebars to be coupled are placed side by side in the field for assembly and the assembly is completed by manually sliding the coupler from right to left (without needing a torque wrench and control apparatus). In this system potential deficient assembly problems to be faced in the field are eliminated and 50% 50% assembly on the rebar is completed without the need for additional control.

System Details:

1 short threaded rebar

1 long threaded rebar

1 plastic protective cover

Reinforcing Bar Couplers- Sleeved Reinforcing Bars

Overlapped inserts are not always appropriate tools for coupling rebars. Regbar Reinforcing Rebar Couplers Using Rebar Couplers simplifies the design and construction of reinforced concrete and reduces the amount of required bars. Regbar Mechanical Reinforcement Couplers provide solutions for construction reinforcement bundles such as overlap and welding.

Our strategy is offering more affordable and extremely safe rebar inserts as compared to the options of overlapping and welding. Regbar Mechanical Reinforcement Couplers and equipment are economic, safe, designer-friendly and easy to apply. In brief, Regbaroffers unique benefits and higher earnings to its customers!

In the Overlapping Method, concrete is required for load transfer. In addition, when the reinforcement reaches the zone of leakage  and its diameter changes, clamping ends and the joint doesn’t work. At joints made by Regbar Reinforcing Rebar Couplers such a clamping is not needed and thus the coupler continues to take up load in keeping with the tensile strength. It delivers outstanding performance at cold joints formed between the floor columns.

Regbar Cold Headed Parallel Thread Reinforcement Couplers cover the processes of cutting bars, cold heading and high profile tangential threading of rebar ends by using Regbar equipment designed for this purpose.

This method provides larger diameter reinforcement ends for thread cutting and loss of cross-section equilibrium. Ends of the rebars previously cut by rebar manufacturers/subcontractors in the field have an undulated surface.

Regbar recommends utilization of professional, highly efficient, cost-effective Reinforcing Rebar Couplers which prevent intensive rebar loss and reduce labor time by professional rebar applicators.

Production Stages

ARegbar Upset Parallel Thread Equipment Setconsists of a rebar cutter or a hacksaw, a high-pressure cold press and a section (cutting ?) thread cutting machine designed for ribbed rebars.


As seen in the attached photos of the mobile equipment which can be quickly installed in the field, our products facilitate thread cutting on the rebar and reduce the logistics cost as the reinforcements will not be transported for thread cutting. All of the machines and equipment provided are designed and manufactured by Regbar. Quality of our equipment has received CE and ISO 9001 certificates. The equipment is shipped to the field in the container area ready for operation. It contains Cold Forging Press, Rebar Thread Cutting Machine, Band Saw and Grinding Machine.
