Complete Solution for your Construction Projects

Re-Bar Couplers are Designed to joint reinforcement bars. The traditional method of connecting reinforcement bars with lap joints continuity in reinforced concrete need not be always appropriate. Advantages of simplicity and economy in lap splicing is limited to smaller diameter bars. Mechanical couplers offer the solution for splicing when large diameter bars are involved.

Technically Superior: Re-bar Couplers performs like continuous reinforcement, develops strength mechanically, independent of concrete. Therefore provides ductility in RCC structures independent of concrete. Proven cyclic performance of rebar offers strength during Man-made, seismic or other natural events. The continuity of rebar offers excellent provision for grounding electrical current.

Re-Bar Couplers reduce rebar congestion and improve concrete flow and consolidation. Offer greater flexibility in design options. The Simplicity in detailing of reinforcement, particularly in reinforcement becomes effortless. Workability with higher steel-to-concrete ratio allows optimum sizing of RCC structural members.

Re-Bar coupler increase production rates because of reduced installation time and simper quality control requirements. Because of these differences, Labor requirements and costs will be substantially reduced.

  •  Reduce steel Wastage
  •  Enable multiple re-use of formworks

General Specification:

  •  Couplers are individual market a allow full traceability of the material
  •  Tensile failure guaranteed to occur way from the joint
  •  No reduction of the ductility of the reinforcing bar
  •  No reduction of the nominal cross section area of the patent
  •  Parallel thread system

Mechanical Splicing System:

  •  Mechanical systems are more reliable than lap systems because they don’t depend on the concrete for load transfer
  •  Mechanical connections offer greater structural integrity. Mechanical splices offer strength and toughness during man-made, seismic or other natural events
  •  Codes require that mechanical splices deliver higher performance than typical design lengths for lap splices. This is typically 125% to 150% greater capacity* provided by the mechanical splice versus the lap splice
  •  Lap splicing increases rebar congestion at the lap zone and is one of the major causes for forming rock pockets and voids in the concrete. Mechanical splices eliminate these congestion problems and will make the overall job more cost effective through minimized job site problems
  •  Building codes stipulate a steel ratio of under 8% and this makes it nearly impossible to achieve a balanced design with lap splicing. Mechanical splices allow the designer to achieve an ideal balance of steel and concrete by eliminating the additional rebar in the lap zone


Due to the increasingly complex demand of the construction industry the design and layout of anchors and splices in reinforced concrete involve a unique combination of art and science.

Practical considerations limit full length continuous reinforcements throughout any sizeable structure. Splicing of reinforcement becomes unavoidable.

The traditionally accepted form of connecting reinforcing steel bars has been by lapping them. The method involves placing two bars together next to each, over a defined minimum length and them holding them in position using wire ties.

After facing all this kind of problem in the fields of construction by using lapping system the VADOL CORPORATION has made a introduction of mechanical splicing system. Which make a new invention in scenario of the construction fields.



  •  Decreased complexities in design and construction
  •  Advancements with hybrid concrete/steel design and standards
  •  Modern constructions techniques
  •  Demand for increased speed in construction
  •  Decrease labor costs
  •  Safety performance criteria


Recently after experiencing all this scenarios, More and more engineers are specifying mechanical rebar connections over lap splices. They’ve found that mechanical connections afford a reliability and consistency that cant be found with lap splicing.

VADOL CORPORATION is a parallel-threaded mechanical splicing system designed for the connection of concrete reinforcing bars Ø16 to Ø40.
