An MBT coupler (Mechanical Bolted Type coupler) is mainly used to join two reinforcement bars (rebars) without welding.
Actual Uses of an MBT Coupler:

• Connecting rebars in construction
  Used to mechanically connect steel bars in RCC structures like buildings, bridges, and foundations.
• When welding is not possible
  Ideal in situations where welding is unsafe, impractical, or restricted (e.g., on-site conditions, high-rise work).
• Repair and extension work
  Helps in extending already installed rebars or fixing damaged bars.
• Maintaining bar strength
  Provides a strong connection without reducing the strength of the reinforcement.
• Quick and easy installation
  Uses bolts to grip the bars, so no special skilled labor (like welders) is required.

Where it's commonly used:

• High-rise buildings
• Bridges and flyovers
• Industrial structures
• Precast construction

What is a Bolted Type Coupler?

A Bolted Type Coupler is a mechanical rebar connection system used to join two reinforcement bars (rebars) using high-strength locking bolts. Unlike threaded couplers, bolted type couplers do not require threading or welding. The steel bars are inserted into the coupler sleeve, and bolts are tightened to create a strong and secure connection.

Why is Bolted Type Coupler Used?

Bolted type couplers are used to provide a strong, reliable, and efficient rebar connection without affecting the strength of reinforcement bars.

1. No Rebar Threading Required 2. No Welding Process 3. Faster Construction 4. Ideal for Congested Areas 5. Better Structural Strength 6. Reduces Steel Consumption 7. Suitable for Repair and Retrofit Work
