An MBT coupler is a type of mechanically bolted rebar coupler used in construction to join two reinforcing steel bars (rebar) end-to-end.

It serves as a strong, reliable alternative to traditional lapping of rebar, offering several key advantages:

• High Strength: Provides a full-tension connection, often stronger than the rebar itself.

• Space-Saving: Eliminates the need for long overlapping rebar, saving space in concrete members.

• Material Efficiency: Reduces steel consumption by avoiding unnecessary overlaps.

• Easy Installation: Joined by tightening high-tensile bolts with a standard wrench, making it faster and less labor-intensive than welding.

• Versatility: Used in critical structures like buildings, bridges, dams, and tunnels for columns, beams, and slabs.

In short, an MBT coupler is a mechanical device that creates a seamless, high-strength joint between two rebar segments, enhancing the integrity and efficiency of reinforced concrete construction.
