Product Media
The BIS Certified Rebar Coupler is a mechanical rebar splicing solution designed to provide a reliable and secure connection between reinforcement bars. It is suitable for RCC construction where dependable reinforcement continuity, structural performance and efficient bar joining are required.
Manufactured for construction and infrastructure applications, the rebar coupler provides an alternative to conventional lap splicing while helping optimize reinforcement placement and reduce unnecessary steel overlap. Its mechanical connection system is suitable for various reinforced concrete structures and demanding construction environments.
Mechanical rebar couplers can help provide continuity between reinforcement bars while reducing the need for conventional lap lengths. They can also help manage reinforcement congestion and improve flexibility during reinforcement installation, particularly in heavily reinforced structural sections.
Rebar couplers should be manufactured and tested according to the applicable Indian standards and project specifications. Quality control may include dimensional inspection, material verification and mechanical performance testing as applicable to the specified coupler type and reinforcement grade.
According to IS 16172:2023, the main types are:
| Classification | Requirement |
|---|---|
| Class H | Low-cycle + High-cycle fatigue |
| Class L | Low-cycle fatigue |

A BIS Certified Rebar Coupler is a mechanical connector used to join reinforcement bars end-to-end. Rebar couplers covered under IS 16172:2023 are intended for mechanical splicing of steel bars in concrete and are subject to specified manufacturing, performance and testing requirements.
The applicable Indian Standard is IS 16172:2023 – Reinforcement Couplers for Mechanical Splices of Steel Bars in Concrete – Specification (First Revision). The standard covers requirements and tests for mechanical splices of reinforcement bars conforming to IS 1786.
Under IS 16172:2023, Class H couplers meet both low-cycle and high-cycle fatigue requirements, while Class L couplers meet the low-cycle fatigue requirement.
Depending on the coupler type and applicable requirements, testing can include static tensile strength, disengagement testing for threaded couplers, percentage elongation, slip testing, cyclic tensile testing, low-cycle fatigue and high-cycle fatigue testing.
A rebar coupler mechanically connects reinforcement bars instead of overlapping them over a lap length. Mechanical splicing can be useful where reinforcement congestion needs to be controlled and where end-to-end mechanical connections are specified for the project.
Check the manufacturer's BIS licence and its exact scope, including the applicable IS number, coupler type, class, reinforcement bar grade and nominal sizes. BIS provides a Know Your Standard facility through which users can access information including licences and testing laboratories associated with an Indian Standard.
