A: First of all, I think you should know when we use re-bar lapping is better and when should we use rebar coupler for splicing? Rebar Coupler is designed to produce a full strength mechanical joint between reinforcing bars, it has the features as below:
- High work efficiency, raw material saving and energy saving;
- No light and noise pollution, not influenced by weather and work-site;
- High strength;
- It can be prefabricated to shorten construction period;
- It can save more cost than steel lapping when the rebar size is over 20mm;
- It can save more space than steel lapping.
