Rebar couplers replace standard rebar lap joints in reinforced-concrete structures. They are also suitable for reinforced-concrete columns and walls. Each rebar coupler consists of a piece of rebar with a threaded end and a coupler sleeve installed on the right side during installation.
Rebar couplers can replace all rebar passing through formwork at construction joints. Historically, lap splicing has been the primary method of load transfer between reinforcement bars.
JB-9 Rebar Couplers with Bar Lock technology are specially designed mechanical splicing solutions used to connect reinforcing bars in modern construction projects. These couplers provide a strong and reliable alternative to traditional lap splicing, ensuring that the load is transferred efficiently from one bar to another without compromising structural integrity.


JB 19 Parallel Thread Couplers are mechanical sleeves used to join reinforcement bars end-to-end, ensuring full continuity of steel reinforcement in concrete structures. They are designed to meet international standards such as BS 8110 for mechanical splices and are widely used in heavy infrastructure projects.
