Cold Forged Rebar Couplers

Cold Forged Rebar Couplers offering strong, durable, and corrosion-resistant connections for heavy-duty construction applications.

Applications:

  • Commercial Buildings: Ideal for constructing high-rise buildings, shopping malls, and office complexes.

  • Infrastructure Projects: Widely used in the construction of bridges, tunnels, and highways.

  • Industrial Facilities: Essential for the framework of factories, warehouses, and production plants.

  • Residential Projects: Provides robust support for modern residential buildings and multi-story apartments.

ShreeShakti Nextgen manufactures Cold Forged Rebar Couplers using high-quality materials like EN8D steel, ensuring exceptional strength and durability. These couplers are designed to meet industrial standards, providing reliable and secure rebar connections. With precise engineering, they offer excellent corrosion resistance, superior load-bearing capacity, and long-lasting performance. Available in various sizes to fit standard rebar specifications, these couplers are easy to install and ideal for demanding construction projects.

Product Features

  • Made from precision-machined EN8D carbon steel for superior strength and durability.

  • Manufactured using cold forging technology, enhancing thread integrity and density.

  • Designed with parallel metric threads for high load transfer without slippage.

  • Compatible with a wide range of rebar diameters and grades.

  • Corrosion-resistant surface finish suitable for aggressive environments.

  • Full-bar-break performance ensures dependable structural continuity.

  • Designed for easy on-site installation, even in congested reinforcement zones.

Maximum length Capcapacity on TMT Bar 12 Meter

Essential Machines Required On-Site

  1. Forging Machine: Strengthens rebar ends for secure coupler connections.
  2. Threading Machine: Precisely cuts parallel threads for seamless splicing.

Bar Preparation

  • Rebar ends are first cold-forged to increase the core area at the bar end.

  • Forged ends are then parallel-threaded using precision threading machines.

  • Threads are matched to the internal threads of the coupler to ensure 100% engagement.

  • The process ensures strong, aligned joints with minimal on-site variation or error.

Benefits of Shreeshakti Cold Forged Couplers

  • Time-Saving Installation: No need for lap splicing; reduces rebar congestion.

  • Steel Saving: Eliminates waste and allows for efficient bar usage.

  • High Strength & Safety: Achieves bar break rather than coupler failure.

  • Improved Site Productivity: Simple installation reduces labor and project timelines.

  • Ideal for All Projects: Suited for bridges, towers, high-rises, precast elements, and seismic zones.

  • Quality Assurance: Every unit is tested under stringent mechanical standards.

Shreeshakti Nextgen Coupler Testing Protocols

Each coupler is rigorously tested to ensure compliance with global standards and performance expectations. Testing is conducted using advanced in-house equipment and certified procedures.

Standard Tests Performed

  • EN8D Material Test – Verifies raw material strength and properties.

  • Tensile Strength Test – Confirms the coupler maintains or exceeds the parent bar’s tensile strength.

  • Elongation Test – Measures ductility and deformation characteristics under load.

  • Location of Fracture – Ensures fracture occurs outside the coupler, indicating full bar break.

  • Distance of Fracture from Coupler – Validates that the joint performs as per design codes.

  • Slip Test – Assesses movement within the coupler to ensure secure mechanical engagement.

  • Bend Test – Evaluates performance under bending stress to mimic on-site forces.

  • Yield Stress Evaluation – Confirms that the system withstands stress beyond the yield point of the bar.

Optional Advanced Testing (Available on Request)

For special infrastructure and seismic applications, we also offer:

  • Cyclic Tensile Testing – Simulates repeated loading and unloading conditions.

  • Low Cycle Fatigue Test – Assesses performance under a small number of high-load cycles (e.g., earthquakes).

  • High Cycle Fatigue Test – Evaluates durability under millions of small repetitive loads (e.g., traffic on bridges).
