Hot Dip Galvanized Steel
Galvanizing Process

Hot Dip Galvanizing is a factory controlled metallurgical combination of zinc and steel that provides corrosion resistance in a wide variety of environments. Hot Dip Galvanizing protects steel from corrosion in two ways. It provides cathodic protection and barrier protection. For over 150 years Hot Dip Galvanizing has had a proven track record of protection in a myriad of applications.Hot Dipped Galvanized Steel Tape

The hot dip galvanized is manufactured using cold rolled steel sheets which is coated with a thin layer of high grade zinc on both sides by hot dip zinc coating process.We export hot dip galvanized Steel Strip, Galvanized Steel Tape and Galvanized Steel Wire manufactured using a continuous process line which ensures high adherence and homogeneous coating thickness.

The final product combines steel resistance and zinc durability, making it fit for roll-forming and highly resistant to environmental rusting. galvanized steel is delivered in strips, coils, tapes and wires . The hot dip galvanized Steel Strip, Galvanized Steel Tape, Galvanized Steel Wire is used for armouring of Telephone Cables, High Voltage Power Cables, Telecommunication Cables and for other general applications.

The basic elements to our galvanizing process are :

» Surface Preparation   » Galvanizing   » Inspection/ Finishing

» Surface Preperation
Surface preparation is the most important step in the application of any coating. In most instances, where a coating fails before the end of its expected service life it is due to incorrect or inadequate surface preparation. With galvanizing, the surface preparation process contains its own built-in means of quality assurance and quality control in that zinc will simply not react with a steel surface that is not perfectly clean. Surface preparation for galvanizing typically consists of three steps:
1. Caustic Cleaning
The caustic tank contains heated water with caustic soda and detergent additives. Oils, soil and soluble paint markings are removed from products during immersion here. Another tank containing plain water is used to remove residues of the caustic dip.
2. Add Pickling
A bath of heated dilute sulfuric acid solution removes rust and mill scale from the products.Another tank containing plain water is used to remove residues from pickling.
3. Fluxing
Zinc ammonium chloride in solution, provides additional cleaning of the products being dipped. During galvanizing, the film of flux on the products improves wetting between the steel and the molten zinc.

In this step, the material is completely immersed in a bath of a minimum of 98% pure molten zinc. The bath temperature is maintained at about 850° Fahrenheit. Fabricated items are immersed in the bath long enough to reach bath temperature. The articles are slowly withdrawn from the galvanizing bath , and the excess zinc is removed by draining, vibrating, and/or centrifuging. The steel then goes into a dilute chromate quench giving your product a longer lasting luster.

» Inspection/Finishing
The most important method of inspection for galvanized articles is visual. A variety of simple physical and laboratory tests may be performed for:

Thickness,
Adherence of the coating,
Uniformity of the coating,
Appearance
