In this civil engineering article, get some vital notes on how to determine the quantity of binding wire for steel bars.

Binding wires stand for mild steel wires which are utilized for binding rebars. They are mainly applied for tying purpose.

Benefits of binding wires:-

• Assist in pouring the concrete into the frames devoid of any misplacement of the rebars.
• To fasten secondary frame designs like chairs, spacer bars in construction.
• Retain lapped bars in exact location.

The quantity of binding wire is based on the followings:-

Type of structure – For heavy structure, the quantity of binding wires will be raised whereas for light structures the quantity will be reduced.

Type of rebar – If the diameter of main bar is increased, the quantity of wires will be reduced and in case the diameter is reduced, the quantity of wires will be raised.

There is no particular method to find out the quantity of binding wires. The calculation can be done on the basis of past experience and thumb rules.

• For 100 Kg steel bars, the quantity of binding wire should be 0.9 to 1.3 Kg.
• For 1000 Kg or 1 ton steel bars, the quantity of binding wire should be 9 to 13 Kg.
• For tying 1 Ton of steel bars with 28 mm or 32 dia, the quantity of binding wire should be approx 7 kg.
