Binding Wire

Binding wires are made from high quality carbon steel making them highly resistant to corrosion and abrasion. In RCC work where we use MS steel bars either plain or ribbed or tor, binding wires are used to bind the steel bars to each other at appropriate place according to design at a spacing defined by the drawing. The steel bars should not be disturbed while lying cements concrete in any of member such as column, beam, slab wall etc.

Quality / Specification

The binding wire should be 16 or 18 gauge annealed wire conforming to IS 280. It shall be free from rust, oil, paint, grease, loose mill scale or any type. It shall be free from corrosion and abrasion and should be abrasion highly stringent. Its tensile strength is half hard i.e. the Tensile Strength 250-430 N/mm2. and Elongation: 40 % @ measuring length of 5.0 x dia.

Precaution while binding

The binding wire should be cut in to pieces from coil for binding. Care should be taken that the length of wire should not be less than 4’’. Take 2 numbers wire and bind diagonally at joint tightly. Do not leave any join, bind all the joints. At some places, there is a practice to bind alternately joints which is wrong practice and reinforcement may loose during laying RCC slab.
