Product Media
16 mm Rebar Coupler is a mechanical reinforcement-bar connection used to join two 16 mm diameter rebars end-to-end. In a parallel-threaded system, the reinforcement-bar ends are prepared with matching external threads that engage with the internal threads of the coupler.
This type of connection is used where a project specifies mechanical splicing of reinforcement bars and can be particularly useful in structural areas where conventional lap splicing may create reinforcement congestion.

Cost-Effective Solution - By eliminating the need for welding and reducing the amount of labor involved, the 16mm Rebar Coupler helps to lower overall project costs without compromising on strength or quality.
Corrosion Resistance - Built to withstand harsh environmental conditions, the coupler offers excellent resistance to corrosion, making it ideal for use in both indoor and outdoor projects, including in marine or other moisture-rich environments.
Precision Engineering - Manufactured with precision, this coupler ensures perfect alignment and a strong bond, providing maximum strength and stability in concrete structures.
Compliance with Standards - The 16mm Rebar Coupler meets international construction standards, offering peace of mind that your projects will comply with local building regulations and safety codes.
1. Bar preparation
The 16 mm reinforcement bar end is prepared according to the manufacturer's procedure.
2. Thread formation
The required external parallel thread is formed on the bar end.
3. Coupler fitting
The threaded bar is inserted into the internal thread of the coupler.
4. Second bar connection
The second prepared 16 mm bar is engaged from the opposite side.
5. Tightening
The connection is tightened according to the approved installation procedure.
6. Inspection
Thread engagement, alignment and installation should be checked according to the manufacturer's/project procedure.
BIS material for IS 16172:2023 identifies performance requirements including tensile strength, disengagement testing for threaded couplers, percentage elongation, slip, cyclic tensile testing, and low- and high-cycle fatigue testing.

Surya Engineering manufactures and supplies mechanical reinforcement connection products for construction and infrastructure requirements. The company website presents its parallel threaded system as a mechanical splicing solution and states that the business was established in 2012.
For project enquiries, buyers should share the rebar diameter, steel grade, coupler type, quantity, project application, required standard/specification and delivery location so the appropriate product can be confirmed.
1. What is the price of a 16mm TMT bar coupler?
16mm rebar coupler price depends on steel rate, quantity and type. Because it is made from EN8D steel, price changes slightly every month.
In India, current market price for 16mm parallel roll thread coupler is Rs. 28 to Rs. 38 per piece for bulk quantity. For small quantity of 100-200 pcs it is slightly higher.
At Surya Engineering we are the manufacturer in Mumbai, so we give best factory price. Price goes down if you order 1000+ pcs. We also give extra discount for contractors and builders. Send us your quantity for same-day best price with test certificate.
2. How heavy is a 16mm rebar?
Weight of rebar is calculated by formula: D x D / 162
For 16mm bar:
1 meter of 16mm TMT bar = 1.58 kg
Standard length of one bar is 12 meters, so
One full 16mm bar (12m) = 18.96 kg to 19 kg
This is same for Fe 500, Fe 500D, Fe 550 grade - weight is based on diameter only.
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.
4. What is the price of a 12mm TMT bar coupler?
12mm coupler is smaller than 16mm, so price is slightly less.
Current market price for 12mm roll thread coupler is Rs. 22 to Rs. 30 per piece for bulk order.
12mm is mostly used in slabs and stirrups. Because its size is small, many people use lapping, but for high-rise and Mivan shuttering projects, 12mm coupler is now compulsory to avoid congestion.
