1. Standard Connection Rebar Couplers
Standard Connection Rebar Couplers are designed for situations that rotations are possible and limitless. By using Standard Connection Rebar Couplers, one steel bar can meet at the opposite side of the end force of the bridge piece. Standard and diameter-varied couplers are optional.
2. Lengthened Connection Rebar Couplers
Lengthened Connection Rebar Couplers are designed for situations that rebars are too long and dense, rotations are limited. Couplers are fully screwed in the lengthened thread of rebar in advance, then reverse screwed in the end thread of the rebar that is being connected. To lock the coupler, just twist the rebar for half to one turn. Standard couplers are optional.
3. Locknut-added Connection Rebar Couplers
Lengthened Connection Rebar Couplers Designed for situations that rebars can't rotate, such as hooked rebars and dockings of bridges, place piles reinforcement cages. Lock the coupler by screwing the locks and rebars in the lengthened thread in advance, then screw in the thread of another rebar's end and lock the coupler with the locknut. Standard and flare couplers with locknuts are optional.
4. Double-sided Thread Connection Rebar Couplers
Double-sided Thread Connection Rebar Couplers are designed for situations that rebars can't rotate but internal forces of the rebars are adjustable, such as construction joints and post cast strips. The coupler is equipped with double-sided threads, which are able to release and tighten two rebars in one direction.
