Rebar Coupler – Upset Parallel Thread
A parallel-thread rebar coupler produced by upsetting (thickening) the bar end before threading, which preserves the bar's full cross-section at the thread – covering Ø12mm to Ø40mm reinforcement for a mechanical splice in place of a lap splice.
Where it's used
Full-Strength Bar Splicing
Upset-threaded ends preserve the bar's full cross-section at the thread, suiting a splice rated close to the parent bar's own strength.
High-Rise & Heavy Structural Reinforcement
Suited to high-load vertical reinforcement splicing in columns, shear walls and transfer structures.
Precast Connection Continuity
Provides reinforcement continuity across precast element joints without a lap splice.
