CERTIFICATION & COMPLIANCE
CERTIFIED TO THE STANDARD THAT MATTER
Every AGBA coupler is manufactured and independently tested to national and international standards with a NABL test certificate shipped on every single batch. The proof travels with your order.
IS 16172:2023
Couplers for mechanical splicing of bars — Class L & H, the governing Indian standard.
ISO 9001:2015
Certified quality management system across manufacturing and dispatch.
ISO 45001:2018
Occupational health & safety management certification at our works.
NABL Tested
Independent lab testing with a signed test certificate on every batch.
Why IS 16172 asks for the forge
FORGED BEFORE THREADED
A splice depends on two halves — a cold-forged bar end and a precision-engineered coupler. In a high-rise column, both carry the load. Cut threads straight into the bar and you sever the grain at every root, reducing the load-bearing section. AGBA upsets the bar end first, so the net section is preserved and grain flows through the threads.
Machined — grain cut
Threads cut into the bar. Cross-section reduced, grain severed — the coupler thread strips under load.

SLIMMER WALL, STRONGER OUTCOME
25% SLIMMER WALL
AGBA couplers meet IS 16172 on thread engagement, tensile and fatigue performance — then go further. A 7.5 mm wall on a 32 mm bar versus a conventional 10–12 mm means engineered clearance, built to pour.
AGBA SLIM WALL
7.5 mm
OD 53 mm · free concrete flow
CONVENTIONAL
10–12 mm
OD 58–62 mm · high pour risk
- Lower honeycombing
- Better concrete flow
- Cost & schedule saving
- Better vibrator access
- Better cover & finish
- Maintains clear cover at the splice
