Hi Sahoo, Binding wire is required to maintain the spacing of the main & distribution reinforcement. Whenever there is maximum tensile load on steel, it wont be displaced from the original position. Further, you need to use around 18gause GI binding wire with 30GSM GI coating. You may contact me through whatsaap for any further queries on 9618909016
