SPPLICETEK’s Cold Forged Parallel Thread Couplers are advanced Rebar Couplers designed to connect concrete reinforcing bars with maximum strength and efficiency. Engineered for TMT Bars ranging from 16 mm to 56 mm, these parallel-thread rebar joint couplers ensure a full-tension splice that maintains the ductility and continuity of the reinforcement without reducing the cross-sectional area.
Our Cold Forged Parallel Thread Couplers comply with IS 16172 standards and are trusted across major infrastructure projects such as high-rise buildings, bridges, metros, and nuclear facilities. With their easy installation and high-performance design, these rebar coupler types are a reliable alternative to lap splicing.
The end of the reinforcing bar is sawn square.
The sawn end is enlarged by a cold forging process to increase the core diameter to a pre-determined size.
The rib of forged bar is removed by turning process for even surface.
A parallel thread is mechanically cut onto the enlarged bar end for precise and secure coupling.
