P-Bar Coupler

SNTP ISI Marked Rebar Couplers

India’s First BIS-Certified Rebar Coupler Under IS 16172:2023

Revolutionizing Reinforcement Splicing – A Flagship by SNTP

The SNTP ISI Marked Rebar Coupler is the flagship product of SNTP Technologies, and a first-of-its-kind innovation in India’s construction sector. Proudly certified by the Bureau of Indian Standards, SNTP is the first company in India to be awarded an ISI mark license under the latest BIS standard IS 16172:2023 for mechanical splicing of reinforcement bars.

SNTP couplers have been developed to meet the growing demand for standardized, high-performance, and reliable reinforcement connection systems, enabling engineers and contractors to build faster, stronger, and smarter.

🔧 Precision Engineering with Cold Forging Technology

SNTP couplers utilize a cold forging process to prepare the bar ends. This method enlarges the bar diameter without reducing its cross-sectional area, maintaining — and in fact enhancing — the mechanical properties of the threaded bar section. Threads are formed using SNTP’s high-precision threading machines, resulting in a parallel thread system that ensures uniform load transfer and high repeatability.

Each threaded bar is proof-loaded to at least the yield strength of the parent rebar, ensuring safety and reliability in every joint.

📘 Manufactured in Compliance with Global Standards

SNTP ISI Marked Rebar Couplers are manufactured under strict quality systems and comply with the following standards:

  • IS 16172:2023 – BIS standard for mechanical splices of reinforcement bars

  • BS EN 1992-1-1:2004 (Eurocode 2)

  • ACI 318 (American Concrete Institute)

  • BS 8110 (British Code for Structural Use of Concrete)

  • ISO 9001:2015 Quality Management System

✅ Key Technical Features & Advantages

  • 🔩 Full Tension Splice: Withstands load beyond 130% of Fe500, Fe500D & Fe550 bar strength

  • 📈 High Tensile Strength: Exceeding 715 N/mm² on hand tightening

  • 🌀 Fatigue Resistance: Proven to endure 2 million+ load cycles

  • ✊ Low Slip Values: Ensures stiffness and structural continuity

  • 🔁 Parallel Thread Technology: Uniform stress distribution, easy engagement

  • 🔄 Positional Applications (Type B Threading): For non-rotatable bar scenarios, the coupler rotates, not the bar. Suitable for horizontal applications

🚧 Application Areas

  • Metro Rail and Tunnel Projects

  • Bridges, Flyovers, and Elevated Corridors

  • Highways and Expressways

  • High-Rise Residential and Commercial Towers

  • Airports, Seaports, and Dams

  • Power Plants and Industrial Infrastructure

METHODOLOGY

  1. Cut: Rebar ends are cut square.

  2. Forge: Bar ends are enlarged using a hydraulic cold forging press.

  3. Thread: Threads are formed on the enlarged ends using SNTP threading machines.

  4. Join: Bars are joined using SNTP couplers.

This method ensures the cross-sectional area remains intact, delivering a splice that matches or exceeds the parent bar’s strength.
