The raw material for the manufacture of wire is the wire rod. The wire machine is a long steel obtained through a steelmaking process. Its basic composition is iron and carbon, the latter presenting different degrees that make the raw material "softer" or "harder", depending on the product to be manufactured. The Hongda search the best options on the market of raw materials according to each type of end product.



During the storage period acquires the raw material impurities. And the stripping, is nothing more than cleaning of these impurities.

The process of reducing the diameter of the wire rod.



After drawing the wire tends to become hard and brittle. Annealing is a heat treatment which allows the drawn wire is again soft and easy to be worked.

It is the process through which the wire will receive the zinc, which has the function of protecting the wire from corrosion.
