Coupler Types & Products
Parallel Threaded Couplers
Atlantis parallel threaded couplers connect reinforcement bars from Ø 16 mm to 40 mm. Rebar threads are parallel threaded by a roller threading machine.
Features
- Cost effective alternative to lap splicing
- Load transfer independent of concrete grade
- Quick and efficient operation
Applications
- Residential Apartments
- Commercial Buildings
- Non-Slender Structures
Cold Forged Couplers
Atlantis cold forged couplers have proven splicing performance under compression, tension, cyclic and fatigue loads. Designed to withstand ultimate tensile performance up to 650 MPa. Rebar ends are enlarged by cold forging and threaded on-site. Recommended for seismic conditions. Available in sizes 16 mm to 40 mm.
- Save cost by reducing rebar consumption
- Positive alignment and locking
- Class L and Class H couplers available
Parallel Thread Couplers
Roller-threaded parallel connections for Ø 16–40 mm bars.
Cold Forged Couplers
Enlarged and threaded ends for seismic and high-load applications.
Reducer Couplers
Connect rebars of different diameters in a single splice.
MBT Couplers
Mechanical bolt-type couplers for specialized connections.
