Wire rods are chosen to comply with related SAE and DIN norms and sustain us to produce directly from high-conductivity (low resistance) ore base wire rod, which do not contain impurities.   Accordingly supplied wire rods are accepted after several chemical and physical tests to process.

With regards to the high conductivity demand of the cable industry, our company uses only iron wire rods, which are made from the iron ore(no scrap iron in it).

Raw materials are subject to acceptance inspections and they are drawn at various diameters depending on the demand of client and standard requirements of the product. The steps are of dry and wet drawing stages depending on the diameter of product. At this drawing stage diameter tolerances are very tight in order to serve our customers with very narrow tolerance limits as per their request.

For flat wires; drawn wires are processed through rolling machine with a high precision, resulting with flat wire with requested diameter. At this stage, it is very important to ensure requested dimensions of the wire and the final product is checked in various controls.

After the drawing stage, the wires are fed into the modern annealing furnace and zinc coating bath in a continuously and tandem line. So the wires are first annealed and then zinc coated at the same time which sustains good adhesion of zinc to the wire.

The annealing eliminates the tension on the raw material and makes the internal structure available for zinc coating. The annealing method is the latest technology and environment-friendly one; no lead is used at this stage and annealing is achieved by pulling the wires through the annealing furnace.

An industrial material, similar to sand is used at this stage, where by flame sand is heated and wires pass through this sand. Since all the surface of wire touch the sand, wires are equally annealed in every part, which completely surrounds the wire.

As surface treatment, wires are passed through acid/water/flux baths several times. Finally Hot-dip galvanizing method is used for zinc coating. The purity of the zinc is 99.995% and the zinc is melted in baths, which are specifically designed for this purpose, and coating is performed.

There are two types of coating process:

1- Zinc Coating: The surface of wire is coated completely with zinc and this is the most common product type.

2- Zinc-Aluminium Coating: The surface of the product is coated with the mixture of zinc and aluminium. Usually, the ratio of materials is 5 units of Aluminium for every 95 units of zinc.

During the galvanization procedure, the diameter of wire is measured with Laser diameter gauges before the wire is fed into bath and after the wire is fed out the bath. Accordingly the final diameter can be achieved in a narrow limit. The hot zinc on wires when wires come out of the zinc bath is wiped by modern nitrogen wiping system. Coating process is completed with accurately adjusted mass of zinc coating and the final figures are very close to the target values.

 

The final product round and flat wires packed in the form of coil, disposable former, on wooden/steel reel depending on the customer requirement. Various protective packaging materials are used depending on the distance of shipment and accordingly products can be safely shipped to the most distant locations all around the world. Our company uses widely recognized packaging sizes, although the products can be packed at different sizes depending on the request of the client.
