Our Products
Standard Parallel-Threaded Coupler
- For same-diameter rebar
- CNC-machined for perfect parallel threading
- Used in beams, columns, slabs, foundations, and shear walls
- Achieves full bar-break tensile strength
Transition Coupler (Reducer Type)
- Connects different diameter rebars
- Example: 32→25 mm, 25→20 mm
- Example: 32→25 mm, 25→20 mm
MBT COUPLER (Mechanical Bolted Type)
- No threading or forging needed
- Shear bolts create a strong mechanical lock around rebar
- Best for: non-rotatable rebars, no threading equipment, repairs, precast elements, and congested reinforcement
- Advantages: Fast installation, compatible with plain/ribbed rebars, perfect for repairs and remote sites.
Weldable Coupler
- Connects rebar to steel elements
- One end threaded for rebar, other end weldable-grade steel
- Ideal for welding rebar to base plates, structural steel, embedded plates, precast connectors, and composite structures
- Benefits: Strong steel–concrete connection, faster installation, cleaner controlled welds, avoids heat damage to rebar.
SIZE RANGE & TECHNICAL DETAILS
Rebar Diameter Range
- India: 12–40 mm
- Export: 10–50 mm (custom)
