Galvanization is the process of applying a protective zinc coating to steel, aluminum and iron, in order to prevent rusting. The term Galvanization is derived from the name of Italian scientist Luigi Galvani. Although galvanization can be done with electrochemical and electro-deposition processes but the most common and popular method in present time is Hot Dip galvanizing, in which steel parts are submerged in a solution of molten zinc.
Process of coating of thin layer of zinc on iron, steel and aluminum at a temperature of about 860 °F (460 °C) by a bath of molten zinc is called Hot Dip Galvanizing. It is a form of galvanization. Oxygen (O2) in the atmosphere reacts with the pure zinc (Zn) to form zinc oxide (ZnO), which forms zinc carbonate (ZnCO3) by reacting with carbon dioxide (CO2) of the atmosphere. Generally it looks dull gray and in many circumstances it stops further corrosion, protects the galvanized material from the effects of outside elements. Rust resistance is the main cause of widely use of steel, and can be recognized by spangles on the surface (The size of crystallites in galvanized coatings is a visual feature, known as spangle).
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.
Cathodic protection is commonly applied to a coated structure to provide corrosion control to areas where the coating may be damaged. It may be applied to existing structures to prolong their life.
Barrier protection is commonly applied to a Hot Dip Galvanizing done surface to protect structure from germs in air or water, which prolongs its life and sustainability.
Prashant Galvanizers expertise of nearly 15 years in galvanizing contractor, manufacturer and supplier of India have an experienced and proficient technicians working team for manufacturing Hot Dip Galvanizing plants. They undertake any kind of critical job like tower line angle, channel and pipe of Shipyard Company, fabrication of tower-line, etc.
Most important and notable fact for Prashant Galvanizers is their un-imaginable capability of manufacturing of automatic/manual galvanizing plant system or 2-in-1 hot dip galvanizing plant system. They have earned a name and fame in a short time among the Galvanizers Consultant in India.
