But why we use a rebar coupler instead of doing a simple lap joint on rebar? Below we listed several reasons for your reference.
Rebar coupler provides uninterrupted structural continuity due to having higher strength than reinforcement. In this way, it offers static advantages, especially in multi-story buildings.

Eliminates the problems of time and labor loss, the formation of air voids at the joints, and exceeding the percentage ratio. Reduces reinforcement density at joints zones.

Reduction of reinforcement density increases architectural strength and this helps the design of small columns and increases the living space.

 Lowers the amount of reinforcement consumed in the project in such a way that this saving cannot be provided by any other item. It offers a significant advantage in terms of purchase, logistics and in-field storage of reinforcement.

Shortens project time by reducing worker and crane usage times and offers cost advantages.

Allows rebar assembly without the need for a lapping joint.

Reduces the quality control frequency and provides quick and easy joining during assembly with no question marks.

Quality control can be done easily with the existing test methods.

Coupled joints have facilitated the construction of heavy reinforcement systems with high strength values all over the world.

Ensures continuity of reinforcement in top-down manufacturing used in subway and top-down projects.
