What is a Rebar Thread Rolling Machine?

A Rebar Thread Rolling Machine is a specialized machine used to form external threads on the ends of reinforcement bars or TMT bars.

Instead of simply cutting material away like a conventional thread-cutting process, a thread-rolling system forms the thread profile using rolling dies. The prepared threaded bar can then be connected to a compatible parallel-threaded rebar coupler.

Simple Definition

A Rebar Thread Rolling Machine is a construction reinforcement machine used to produce accurate external threads on TMT/reinforcement bars for mechanical rebar splicing.

Surya Engineering lists machines with capacities such as 1640 mm bar diameter, making them suitable for common reinforcement-processing application.

Rebar Threading Machine Price in India

The price of a Rebar Thread Rolling Machine in India depends on the machine model, automation, bar diameter, threading method, motor, accessories and configuration.

For example, Surya Engineering currently lists a Rebar Thread Rolling Machine at approximately 71,900 per unit on its public product listing. The listed machine has a 1640 mm diameter range, 3-phase power and semi-automatic mechanical operation.

Other Surya Engineering rebar threading models are publicly listed at different prices, including machines around 69,000, 90,000, 95,000 and higher, depending on the model and configuration.

Therefore, the actual Rebar Threading Machine price should be confirmed with Surya Engineering based on your required bar diameter, model and specifications.

Indicative Price Example

These are publicly listed prices, not a universal market price, and prices can change with configuration, GST, transportation and accessories. 

Why is a Rebar Thread Rolling Machine Used?

The main purpose of the machine is to prepare reinforcement bars for mechanical threaded splicing.

It is used to:

• Produce threads on TMT/rebar ends
• Prepare bars for threaded rebar couplers
• Create consistent thread profiles
• Support mechanical reinforcement splicing
• Reduce dependence on conventional lap joints where mechanical splicing is specified
• Improve reinforcement-processing productivity
• Support large construction and infrastructure projects
• Process multiple reinforcement bar diameters
• Reduce manual thread preparation
• Improve repeatability of threaded bar preparation

Mechanical splicing can be particularly useful with large-diameter reinforcement because it can reduce reinforcement congestion and speed construction. BIS specifically identifies these benefits of mechanical splicing.

How Does a Rebar Thread Rolling Machine Work?

A typical process is:

TMT/Rebar Bar Preparation Clamping Thread Rolling Thread Inspection Threaded Coupler Connection

1. Bar Preparation

The reinforcement bar is cut/prepared according to the required project dimensions.

2. Bar Positioning

The bar is positioned and securely clamped in the machine.

3. Thread Rolling

Specialized rolling dies form the required external thread profile on the bar end.

4. Thread Inspection

The finished thread is checked for dimensions, profile, length and compatibility with the selected coupler.

5. Coupler Installation

The threaded reinforcement bar is connected to the corresponding threaded rebar coupler according to the approved installation procedure.

Classification of Rebar Threading Machines

Rebar threading machines can be classified according to their operating method and threading technology.

1. Rebar Thread Rolling Machine

Uses rolling dies to form threads on reinforcement bars.

Suitable for: Parallel-threaded mechanical coupler systems.

2. Parallel Thread Rolling Machine

Produces parallel external threads suitable for compatible parallel-threaded couplers.

3. Taper Threading Machine

Produces tapered threads for compatible tapered-thread mechanical coupling systems.

4. Chaser Threading Machine

Uses thread chasers/cutting tools to produce the required thread profile.

5. Portable Rebar Threading Machine

Designed for applications where mobility and site-based reinforcement processing are important.

6. Automatic / Semi-Automatic Threading Machine

Machines can also be classified according to automation level.

Surya Engineering publicly lists semi-automatic, manual and automatic rebar-threading models, including portable and specialized machines.

Applications of Rebar Thread Rolling Machine

A Rebar Thread Rolling Machine can be used in:

Building Construction

• Residential buildings
• Commercial buildings
• High-rise buildings
• RCC structures

Infrastructure

• Bridges
• Flyovers
• Metro projects
• Railway projects
• Tunnels
• Industrial infrastructure

Reinforcement Processing

• Rebar fabrication yards
• Steel reinforcement workshops
• Construction sites
• Precast manufacturing
• RCC column reinforcement
• Beam reinforcement
• Shear wall reinforcement
• Foundation reinforcement

Mechanical Coupler Applications

Threaded reinforcement bars are used with compatible parallel-threaded or other threaded mechanical couplers to create mechanical splices.

Installation & Machine Setup

The machine should be installed on a stable, level surface with sufficient space for bar feeding, operation and maintenance.

Basic Installation Steps

Step 1 Select the Location
Choose a clean, stable and adequately ventilated working area.

Step 2 Level the Machine
Place the machine securely and ensure proper alignment.

Step 3 Electrical Connection
Connect the machine to the specified electrical supply through suitable protection and earthing.

Step 4 Install Threading Dies
Install the correct rolling dies/chaser components for the required bar diameter and thread specification.

Step 5 Adjust Thread Parameters
Set the required thread length, pitch and other machine parameters according to the machine manual and coupler specification.

Step 6 Test Run
Run the machine without production load and check abnormal noise, vibration and operation.

Step 7 Trial Thread
Process a sample bar and inspect the resulting thread.

Step 8 Production
After confirming the thread quality, start regular production.

Important: Electrical installation, die selection, machine adjustment and operation should follow the manufacturer's manual and applicable safety requirements. Do not rely only on generic settings because thread dimensions must match the selected coupler system.

IS Standard & Testing for Rebar Threading Machines

There is an important distinction here:

The machine itself is not the same as the rebar coupler standard.

IS 16172:2023 is the Indian Standard for Reinforcement Couplers for Mechanical Splices of Steel Bars in Concrete. It is not a product standard specifically for a rebar-threading machine.

For a threaded rebar system, the finished mechanical splice and reinforcement bars should meet the applicable project and BIS requirements.

Important Indian Standards

IS 16172:2023
Reinforcement Couplers for Mechanical Splices of Steel Bars in Concrete Specification.

IS 1786
High Strength Deformed Steel Bars and Wires for Concrete Reinforcement.

IS 16172:2023 covers mechanical couplers used with reinforcement bars conforming to IS 1786.

Coupler Testing

Depending on the coupler type and applicable requirements, IS 16172:2023 includes performance tests such as:

• Static tensile test
• Disengagement test for applicable threaded couplers
• Percentage elongation
• Slip test
• Cyclic tensile test
• Low-cycle fatigue test
• High-cycle fatigue test
• Workmanship and finish
• Dimensional/nominal-size checks

The exact tests depend on the coupler type and class. BIS classifies reinforcement couplers into Class H and Class L, with different fatigue-performance requirements.

Thread Quality Matters

For a threaded rebar system, the machine should produce threads that are compatible with the specified coupler. The thread diameter, pitch, length, profile and dimensional tolerance should be checked according to the manufacturer's approved process and the applicable coupler specification. 

Advantages of Rebar Thread Rolling Machine

7. Suitable for Fabrication Yards

The machine can be used in reinforcement-processing and fabrication facilities.

8. Supports Large RCC Projects

Threaded reinforcement systems are useful for buildings and infrastructure projects where mechanical splicing is specified.

9. Better Workflow

Bar preparation, threading and coupler installation can become a more organized reinforcement-processing operation.
