3) Several types of splicing, which could be suitable for rebar splicing when the rebar cage or the
bending rebar is used;
4) High production eficiency, it only takes less than 1 minute to upset and make one thread on the site;
5) High adaptability, the splicing could be conducted when the power is off, or under water, or at
super high position, or windy, rainy and snowy weather.
6) Environment-friendly, material-effective.
7) Inexpensive to purchase, maintain and repair.
8) The splicing could be produced in advance without influencing the construction period.
9) Manufactured under strict quality assurance plan ISO 9001.
