20mm Rebar Coupler

Available Coupler Types

Depending on the product range, 20mm reinforcement can be mechanically spliced using different coupler configurations:

Standard Coupler – for conventional end-to-end bar connections where installation conditions allow the required bar rotation.

Position Coupler – for applications where reinforcement bars cannot freely rotate during assembly.

Reducer Coupler – for connecting bars of different nominal diameters, where the specific coupler is designed and qualified for that connection.

Transition Coupler – for specific bar/grade or connection arrangements where the manufacturer's product is designed and approved for the application.

20mm Rebar Coupler Applications

The 20mm size can be used in project-specific mechanical reinforcement connections such as:

• ---

• Testing & Quality Control

• BIS information for IS 16172:2023 includes tests such as tensile strength, disengagement for threaded couplers, percentage elongation, slip, cyclic tensile testing, and low- and high-cycle fatigue testing.

• ---

• Benefits of a 20mm Mechanical Rebar Coupler

• A mechanical splice can be useful where the project design specifies a mechanical reinforcement connection. Depending on the structural arrangement, it can help reduce reinforcement congestion associated with lap splices and provide a defined mechanical connection between bars.
• The actual structural performance and suitability depend on the coupler design, bar grade, installation procedure, qualification/testing and project requirements.

• FAQ

•  

• 1. Which companies manufacture rebar couplers in India?

• Rebar couplers are manufactured by both international brands and Indian factories. Major manufacturers in India are:

• a) Surya Engineering - Mumbai - Direct factory at Bhayandar, Mumbai. Manufacturer of parallel roll-thread couplers for 12mm to 40mm as per IS 16172. Ready stock and machine support across Maharashtra and pan-India. This is us.

• b) Dextra India - International brand, premium range, mainly for metro and large infrastructure projects.

• c) Bartec & Ancon - UK technology brands with plants in India.

• d) Local Manufacturers in Pune, Chennai, Delhi NCR - Many small factories make cut-thread couplers, but for roll-thread and IS certified quality, builders prefer established manufacturers like Surya Engineering.

• If you are looking for a Rebar Coupler Manufacturer in Mumbai, Surya Engineering is a local factory - you can visit, see testing and take same-day delivery, which traders cannot give.

2. How much does a rebar coupler cost?

Rebar coupler cost depends on 3 things:

• Diameter - Bigger dia = higher price. 12mm is cheapest, 32mm is costliest.
• Type - Standard coupler is cheapest. Positional and Transition couplers cost 25-30% more.
• Quantity & Steel Rate - Price of EN8D steel changes every month, and bulk orders get better rates.

Current market price range in India for Standard Roll-Thread Coupler:

• 12mm - for price
• 16mm - for price
• 20mm - for price
• 25mm - for price
• 32mm - for price

This is for standard type with IS 16172 certification. For best factory price, always contact manufacturer directly instead of trader.

3. What are the different types of rebar couplers?

There are mainly 5 types we manufacture at Surya Engineering:

a) Standard Coupler - Most used. For joining where one bar can rotate. Used for 16mm, 20mm, 25mm, 32mm.

b) Positional Coupler - Has two parts with locknut. Used when both bars cannot rotate, for repair and precast work.

c) Transition Coupler - For joining two different diameters, like 16mm to 20mm or 12mm to 16mm.

d) Weldable Coupler - One side has thread for rebar, other side is plain for welding to steel structure or plate.

e) Roll Thread vs Cut Thread - Roll thread is advanced type where threads are made by rolling, not cutting. It keeps 100% bar strength. Cut thread is old type where threads are cut and bar becomes weak. We recommend only roll thread as per IS 16172.
