Cold Forged Threaded Couplers

Cutting the Rebar

The ends of the reinforcement bars are cut square for proper alignment.

Threading the Ends

Parallel threads are machined onto the rebar using a threading machine.

Installing the Coupler

The coupler is screwed onto one bar, then the second bar is aligned and screwed in from the opposite side.

Tightening the Connection

A wrench is used to ensure full engagement and tightness, creating a secure splice.

High Strength and Reliability

Provides a direct bar-to-bar connection with full tensile capacity, eliminating weak points common in lap splicing.

Reduced Rebar Usage

No overlap means less steel consumption and cost savings.

Faster Construction

Quick installation speeds up project timelines and reduces labor costs.

Space Efficiency

Ideal for congested reinforcement areas where overlapping is impractical.

Seismic Resistance

Continuous load transfer enhances structural stability during earthquakes.

Easy Quality Control

Visual inspection of threads and coupler alignment ensures reliable joints.

Step 1: Preparation

• Cut rebar ends cleanly and remove rust or dirt.

Step 2: Threading

• Use a parallel threading machine to cut threads to the required length.

Step 3: Assembly

• Screw the coupler onto the first bar and align the second bar for connection.

Step 4: Final Tightening

• Use the recommended torque to secure the joint.

Step 5: Inspection

• Check alignment and tightness before pouring concrete.

High-rise buildings

Vertical and horizontal reinforcement continuity.

Bridges and flyovers

Handling high tensile forces.

Precast concrete structures

Quick assembly of precast components.

Industrial projects

Dense reinforcement zones need space efficiency.

Seismic areas

Structures requiring enhanced earthquake resistance.

Material Efficiency

Couplers save steel by removing overlap length.

Strength

Couplers provide full bar strength; lap splicing depends on bond strength.

Construction Speed

Faster and more straightforward than overlapping bars.

Space Management

Reduces congestion, improving concrete compaction.
