Indented PC Wire

The pre-stressed steel wire is tensioned approx. 70 to 80% of the minimum specified breaking load of steel wire prior to casting of concrete. Indented PC WireAfter initial setting of concrete, the pre-tensioned steel wire is released and the stress in the wire is induced in the concrete. This induced compressive stress will neutralize the tensile stress caused by the acting loads on the concrete member. In the case of pre-tensioning, it is important that adequate bond is created between the steel wire and concrete in order to transfer the desired compressive force from the steel wire to the concrete.

In order to improve the bond strength and achieve a consistently low transmission length, regular indentations of specified shape in the wire surface in either opposite or 120-degree planes or 90-degree planes were introduced. In the known art of indenting operation, it is possible only to make 2, 3 or 4-sided intermittent indentation on the surface of the wire. This indentation is normally carried out on a wire-drawing machine and is effected by pulling the wire through appropriate indenting rolls.

Advantages

We can produce two-sides, three-sides, four-side indented PC wire, and the products with different diameters, different tensile strengths, and different national standards. At present, our product has been applied in Australia, America, Britain, Brazil etc. more than 20 countries.
