Product Picture


Introduction: Rolling Parallel Thread Rebar couplers are devices used to join lengths of rebar together, allowing to quickly and safely create a high performance splice on the construction site. Usually, the rebar ends need to be prepared to connect two bars. This is done by specific equipment which DLADTO has engineered and manufactured.


Product Advantage:

1.Raw Material -Saving,high energy saving,high work efficiency.

2.Construction Environmental Protection, no frame, no noise pollution.

3.It is not be effected by the chemical composition and types of reinforced bars and won’t be influenced by weather and work-site.

4.Low cost, simple operation

5.Can be prefabricated and the construction period can be shortened

6.High dimension precision,reliable quality and stable performance.

7.High strength. The tensile strength usually more than 600 Mpa, it can reach 110% of yield strength of parent rabe.

8.After 2 million times of fatigue strength test, the connection is in good condition.

9.According to the inspection of National Construction Quality Supervision and Testing Center, the rebar coupler joint performance has reached the Grade I splicing rebar joint of JGJ107-2016 Industry Standard.
