Galvanizing process

Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc. This reaction is a diffusion . The galvanizing process has its own built-in means of quality control because zinc will not react with an unclean steel surface.

Any failures or inadequacies in surface preparation will be immediately apparent when the steel is withdrawn from the zinc bath because the unclean areas will remain uncoate and immediate . Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting.

The most common method is hot-dip galvanizing , in which parts are submerged in a bath of molten zinc. Home Technical Galvanizing Process. The zinc coating protects the surface against corrosion by providing protection to the iron or steel in two . With a year history we are considered industry experts in all phases of the hot dip galvanising process. Organic surface contaminants, such as oils and some paint, are carefully removed from the steel by suitable preliminary treatment, usually via a caustic solution. Some paints, lacquers and oils may need to be removed prior to the arriving at the galvanizing plant.

Inspection - Items are inspected to ensure they are safe and suitable to galvanize. Surfaces are checked for signs of contamination with paint, grease, etc. These layers have unique mechanical properties, which ensure the best conditions for adhesion and impermeability.

Hot dip galvanizing is the process of coating iron or steel articles with zinc by immersing the metal in a molten zinc at a temperature of around 450°C. Metallic zinc coatings are applied to prepared steel surfaces by galvanizing, electroplating, mechanical plating, sherardising, painting with zinc-rich coatings and zinc spraying or metallising. Of these the galvanizing process is by far the most widely used.

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. The hot dip galvanizing is a process of applying zinc coatings to components in steel or iron by immersing the component in a bath of molten zinc. The simplicity of the hot dip galvanizing process is an advantage on other methods of corrosion protection. Technological procedure includes four main stages. In the first stage, the elements are hanged on special beams with wires or chains.

The beams on which the elements are hung are transported with cranes during whole procedure. Galvanizing can also protect metal through a process called “galvanic corrosion”. Galvanic corrosion occurs when two metals of a different electrochemical make up are placed into contact with one another with an electrolyte present, such as salty water. Depending on the atomic structure of the two metals, . The oldest and longest tenured hot-dip galvanizing plant in the Western United States.
