Advantages:
Installation guide
1. Cutting
one end of reinforcing bar is cutting sawn square
2.Cold forging
The sawn end of rebar is enlarged by a patented cold forging machine, the core diameter of the bar is increased to a pre-determined diameter.
3.Threading
At last, make thread on the end of the bar which has been enlarged.
