pouring process.
Vruddhi Couplers Testing
Our commitment to quality is unwavering, and we subject our products to rigorous testing to ensure their reliability.
- Static Tensile Test : The Tensile strength of the mechanical splice shall be as follows:
(a) If greater than 130% of Fy; Location of failure can be anywhere
(b) If lesser than 130% of Fy; Location of failure should be outside the length of the mechanical splice(L)]
Fy = Minimum yield stress as per the rebar gradeL = 2D (D is size of rebar)] - Slip Test : Total slip for the spliced sample should be less than 0.10 mm.
- 100 Cycles Test : The rebar coupler joint shall withstand 100 cycles of stress variation, simulating the loading experienced in tall and stack-like structures.
- Low Cycle Fatigue Test : The mechanical splices shall withstand 10,000 cycles of alternating tension and compression loads.
- High Cycle Fatigue Test : The mechanical splices shall withstand 20 Lakh cycles of alternating tension and compression loads.
Vruddhi Rebar Coupler Testing
To ensure the highest quality and performance of Vruddhi Rebar Couplers, we conduct a series of rigorous tests. Below are the key tests with their detailed descriptions:
1) Static Tensile Test
Image: [Insert Static Tensile Test Image]
The Static Tensile Test measures the maximum tensile strength of the rebar coupler. In this test, the coupler is subjected to increasing tension until it fails. This ensures that our couplers can withstand the maximum stress they might encounter in a construction environment.2) Slip Test

The Slip Test evaluates the coupler's ability to maintain a secure grip on the rebar under stress. This test involves applying a load to the coupler and measuring any movement or slip between the rebar and the coupler. This ensures that our couplers provide a reliable and stable connection.
3) 100 Cycle Test
Image: [Insert 100 Cycle Test Image]
The 100 Cycle Test assesses the durability of the coupler through repeated loading and unloading cycles. The coupler is subjected to 100 cycles of load application to simulate the stress it will experience over time in real-world conditions. This test ensures that our couplers can endure repeated stress without compromising their integrity.
4) Low Fatigue Test

The Low Fatigue Test evaluates the coupler’s performance under low cyclic loads. This test involves applying low levels of stress repeatedly to the coupler to simulate the conditions it will face in certain construction environments. This ensures that our couplers perform reliably under such conditions.
5) High Fatigue Test

The High Fatigue Test measures the coupler’s endurance under high cyclic loads. The coupler is subjected to high levels of stress repeatedly to simulate the extreme conditions it might face. This test ensures that our couplers maintain their integrity and performance even under severe stress.
Unique Identification Number (UIN) for Vruddhi Rebar Couplers
At Vruddhi, we implement a Unique Identification Number (UIN) system to ensure the highest level of traceability and quality control for our Rebar Couplers. Each coupler is marked with a unique code, allowing for end-to-end traceability throughout the entire supply chain.
Benefits of UIN:
1. Traceability: The UIN enables us to track each coupler from the raw material stage through to final delivery, ensuring complete traceability.
2. Quality Assurance: With the UIN, we maintain strict quality norms across the entire supply chain, guaranteeing that only the highest quality couplers reach our clients.
3. Accountability: The unique code on each coupler holds us accountable for every step of the manufacturing and delivery process, ensuring consistency and reliability.
By implementing the UIN system, Vruddhi ensures that our Rebar Couplers meet stringent quality standards and deliver exceptional performance in all construction applications.
