Rebar couplers are temporary sleeves used in steel reinforced concrete structures. They are directly fixed onto the reinforcing bars, creating a strong connection and easily passing through the membrane formed during concrete pouring. There are seven major advantages of using rebar couplers in on-site construction:

1. Efficiency: Rebar couplers employ simple and quick operation methods, making the connection between reinforcing bars easier. This allows for swift installation on-site, significantly improving worker efficiency during construction.

2. High Precision: When using rebar couplers to connect reinforcing bars, the accuracy of their installation position and clamping force is ensured. This reduces errors in the verticality of the rebars, resulting in components with more precise dimensions and correct geometric shapes.

3. Material Savings: Compared to welding methods, rebar couplers can save a significant amount of steel when connecting rebars. This can lead to substantial material cost savings during on-site construction while maintaining connection quality.

4. Environmental Friendly: As rebar couplers are used as temporary sleeves in structures, they can be easily removed and recycled after use. This reduces waste generated during construction and minimizes environmental impact.

5. Flexibility: Rebar couplers can be used between rebars of different diameters and lengths, making them an ideal choice for various structures. Even for rebars that require cutting into special shapes and sizes on-site, couplers can easily facilitate the connection.

6. High Bearing Capacity: Rebar couplers feature a dense serrated structure, providing strong clamping force and bearing capacity. This means fewer connection components are required, allowing for greater bearing capacity on building structures.

7. Significant Economic Benefits: Rebar couplers offer convenience, speed, and wide applicability. This makes them a cost-effective connection method, reducing labor costs and material waste while enhancing the quality of building structures.

Overall, rebar couplers offer significant advantages during on-site construction, improving efficiency, reducing material costs, preserving the environment, and providing high-strength connections for building structures.
