SNTP Technologies: India's Largest Rebar Coupler Maker Setting New National Standards

India’s construction sector is witnessing a historic transformation, powered by the demand for safer, stronger, and globally aligned reinforcement technologies. Leading this revolution is SNTP® Technologies, today recognized as India’s largest rebar coupler manufacturing conglomerate, with an extraordinary annual capacity exceeding 5 million couplers. Our commitment to innovation and quality has positioned SNTP at the forefront of the nation’s infrastructure growth story.

A Historic First for India: BIS Certification with the ISI Mark

In a breakthrough moment for the industry, SNTP Technologies became the FIRST company in India to receive the BIS License for ISI Mark Rebar Couplers under IS 16172:2023. This achievement is not only a milestone for SNTP but a defining moment for India’s construction standards. For decades, the country relied heavily on traditional lap splicing—leading to steel wastage, reinforcement congestion, and structural compromises.

SNTP’s ISI Mark Rebar Couplers now rewrite the rules by offering a certified, engineering-backed, and globally compliant alternative. With bar-break strength exceeding 750 MPa—far surpassing Fe 500/500D/550D rebars—our couplers ensure maximum structural performance. They have also passed high fatigue tests beyond 2 million cycles, making them ideal for metros, bridges, expressways, seismic zones, and megaprojects where reliability is non-negotiable.

Built to Global Standards, Engineered for India

SNTP ISI Mark Couplers are fully aligned with Eurocode 2 and ACI benchmarks, placing Indian infrastructure on par with international engineering practices. Our precision parallel-threaded systems offer up to 40% steel savings by eliminating long lap lengths and significantly reducing on-site congestion. For engineers, contractors, and project heads, this is more than a compliance certification—it represents a major shift toward leaner reinforcement, faster execution, and safer structures.

Manufacturing Excellence with ISO 9001:2015 & BIS Certification

Our state-of-the-art manufacturing facility is both ISO 9001:2015 certified and BIS Certified, equipped with advanced threading systems, calibrated torque tools, CNC inspection modules, and BIS-approved testing infrastructure. Every coupler undergoes rigorous checks:

• Lot-wise acceptance tests as per IS 16172 Table 1
• Tensile, Thread Disengagement Test, proof load, and slip verification
• Dimensional & mechanical accuracy inspections
• Type testing (2 million Cycles-High Fatigue, 10000 Cycles-Low Fatigue, 100 Cycles)
• Full batch traceability and documented quality control

These processes ensure that every ISI Mark coupler meets the highest engineering standards before reaching project sites.

Innovation Continues: Introducing SNTP SnapFit® Couplers

While ISI Mark Couplers remain our flagship offering, we continue to push the boundaries of construction technology. Our SNTP SnapFit® Rebar Couplers provide ultrafast, threadless installation, enabling rapid progress on high-speed and time-critical projects. With SnapFit®, SNTP remains ahead of industry needs and aligned with future-ready construction demands. 

Empowering India’s Mega Infrastructure Vision

SNTP Technologies proudly supplies its certified solutions across the country—from metros to ports, bullet train corridors to hospitals, dams to high-rise buildings. As India rapidly expands its urban and national infrastructure, certified mechanical splicing is no longer optional—it is essential.

With innovation as our core and quality as our foundation, SNTP Technologies is honoured to set a new benchmark for India’s construction ecosystem—one coupler at a time
