Parallel Thread Rebar Coupler Supplier

Parallel Thread Rebar Coupler Supplier | Leo Industries

Parallel Thread Rebar Coupler Supplier

As a trusted parallel thread rebar coupler supplier, Leo Industries delivers high-performance mechanical splicing systems designed for modern construction challenges. Our parallel thread couplers ensure a full tension splice, providing a connection that is often stronger than the reinforcement bar itself. By utilizing high-grade raw materials and precision engineering, we help contractors reduce steel congestion and improve structural stability in high-rise buildings, bridges, and infrastructure projects.


Working Principle & Process Flow

The process begins with the preparation of the rebar ends. First, the bar ends are cut square. Then, the ends are upset using a cold forging machine to increase the diameter, followed by threading using a specialized parallel threading machine. This ensures that the cross-sectional area of the thread is not less than the original bar area. Finally, the parallel thread coupler is screwed onto the threaded ends of the two bars and tightened to the required torque, creating a seamless mechanical joint that facilitates efficient load transfer.

Maintenance & Safety Tips

Checklist Leoindustries

Pre-Installation

  • Inspect threads for any damage, dirt, or concrete slurry before assembly
  • Ensure rebar ends are protected with plastic caps until ready for use
  • Verify that the coupler grade matches the rebar specification

Installation Practices

  • Use a calibrated pipe wrench or torque wrench for final tightening
  • Ensure the bars are centered within the coupler for equal thread engagement
  • Conduct periodic pull-out tests to verify the integrity of the splicing system

FAQs — Parallel Thread Couplers

Q1 What is a parallel thread rebar coupler?
It is a mechanical splice used to join two rebars with parallel threads. Unlike tapered threads, parallel threads maintain a constant diameter, ensuring high load-bearing capacity and a secure fit.
Q2 Why should I choose parallel thread over lap splicing?
Parallel thread couplers eliminate the need for overlapping steel, which saves material, reduces weight in the structure, and prevents congestion, making concrete pouring much easier and more effective.
Q3 Is special machinery required for these couplers?
Yes, the rebar ends must be threaded using a parallel threading machine. As a leading supplier, we often provide these machines to project sites to facilitate smooth operations.
Q4 Can parallel thread couplers be used for different bar sizes?
Yes, we supply transition or reducer parallel thread couplers specifically designed to connect bars of two different diameters securely.
Q5 Do your couplers meet Indian and International standards?
Absolutely. Our products are manufactured to comply with IS 16172 and other global standards, ensuring they meet the safety and performance criteria required for major infrastructure projects.
