Product features: most suitable to connect two different size rebars
When storey connected, there may require to connect different sizes of rebars due to the design requirements. For example, the rebar used in basement is 32mm, but for the storey is 25mm, so how to connect this two different size rebars? JBCZ customize and design reducing coupler for clients which can easily solve this problem.
First, upset forge the end of the two different sizes of rebars, such as one rebar is 32mm and the other is 25mm, then process thread on the forged bar end.
Second, JBCZ customized reducing coupler, 50% of the thread is 32mm, and the other 50% is 25mm to match the rebar size above.
Third, to connect two rebars normally, the connection process can be finished within 35 seconds.
In order to make you learn more about reducing coupler, JBCZ international department takes the operation video for your reference.
