What is an MBT Rebar Coupler?
An MBT Rebar Coupler is a mechanical connector that joins two reinforcement bars using specially designed lock bolts. Unlike threaded couplers, MBT couplers do not require bar threading, making them ideal for repair work, retrofit projects, and situations where bar preparation is difficult.
Why is MBT Rebar Coupler Used?
- No threading required
- No welding required
- Quick and easy installation
- Suitable for existing structures
- Reduces construction downtime
- Provides strong mechanical connection
- Ideal for congested reinforcement areas
- Useful for repair and extension work
Classification of MBT Rebar Couplers
1. Standard MBT Coupler
Used for joining bars of the same diameter.
2. Transition MBT Coupler
Connects reinforcement bars of different diameters.
3. Repair MBT Coupler
Used for damaged or replacement reinforcement bars.
4. Heavy-Duty MBT Coupler
Designed for high-load and infrastructure projects.
Applications
MBT Rebar Couplers are widely used in:
- High-rise buildings
- Residential projects
