Parallel threaded mechanical splicing systems for reinforcement bars from 12 mm to 40 mm. Manufactured in compliance with IS 16172, ACI 318, BS 8110, and ASME Sec III Div 2 under ISO 9001 quality management.
Kridhan Couplers are Parallel Threaded Mechanical Splicing systems designed and manufactured for the connection of concrete reinforcement bars ranging from 12 mm to 40 mm diameter. Manufactured in compliance with IS 16172, ACI 318, BS 8110, and ASME Sec III Div 2, following the ISO 9001 quality management system.
The thread manufacturing process combines engineering expertise across three types of machinery - Threading machine, Forging machine, and Power pack - ensuring consistent precision in every coupler produced.
Kridhan rebar couplers are engineered to outperform conventional lapping in strength, efficiency, and economy - suitable for all structural grades.
Request QuoteReduces rebar congestion problems on-site
Reduces rebar steel wastage significantly
Easy to install, shortening construction cycle time
No staggering of spliced rebars required
No reduction in rebar cross-section due to cold upsetting process
Effective and economical alternative to conventional reinforcement lapping
Enables multiple re-uses of formwork
Kridhan offers four coupler variants to suit every structural requirement from standard connections to restricted access situations.
Kridhan Couplers meet or exceed the structural requirements of all major international codes - from Indian Standard to ASME nuclear-grade qualification.
IS 16172 requires 130% of Fy (yield strength). For 500 grade rebar (Fy = 500 MPa), the coupler must withstand a minimum tensile strength of 130% × 500 = 650 MPa.
ACI 318 requires 125% of Fy. For 500 grade rebar (Fy = 500 MPa), the coupler must withstand a minimum tensile strength of 125% × 500 = 625 MPa.
BS 8110 requires 125% of Fy. For 500 grade rebar (Fy = 500 MPa), the coupler must withstand a minimum tensile strength of 125% × 500 = 625 MPa.
Kridhan Coupler is also qualified as per UK CARES, ASME Section III Division 2, and Caltrans - covering nuclear-grade and highway infrastructure requirements.
Kridhan Couplers are independently tested and validated by NABL Accredited, ISO Certified, and Government Approved laboratories across India and internationally.
