A Cold Forged Rebar Coupler is a mechanical reinforcement bar joining system manufactured through a cold forging process, where steel is shaped under high pressure at room temperature to improve its strength and grain structure.
The coupler is internally threaded after forging and is used to connect two reinforcement bars securely without lap splicing. Cold forging increases dimensional accuracy, improves mechanical properties, and enhances load-bearing performance.
Cold forged couplers are commonly used as a replacement for conventional lap joints because they reduce steel consumption, improve reinforcement continuity, and provide better concrete flow in congested reinforcement zones.
Modern RCC structures require reinforcement connections capable of transferring tensile, compressive, and seismic loads effectively.

Surya Engineering Cold Forged Rebar Couplers undergo rigorous testing to ensure compliance with Indian and international standards.
The Go/No-Go Gauge Test is one of the most important quality inspections for threaded couplers.
The "Go" side must pass completely through the thread profile, while the "No-Go" side must not pass beyond the permissible limit.
This test helps ensure:
