It is a form of "chemical mechanical bathing" of the metal that enables the formation of metallic oxides that prevent corrosion. This corrosion protection technique has been proven to be reliable, cheap, and durable with less harm to the environment. The process of galvanizing (bathing a metal with metal to form oxides resistant to corrosion) from which hot dip galvanizing is made has existed for more than 250 years and has been a mainstay of the industry since the early 20th century. It is used in different manufacturing processes to produce steel with unmatched protection from the ravages of corrosion. From roofing nails to highway guardrail, to Brooklyn Bridges suspension and to NASA's launch pad sound suppression systems, galvanizing has provided means to protect materials from corrosion successfully.

In addition, the main component of galvanizing, zinc is readily available- about 25th in the order of abundance from the earth crust. This component is a mineral that is essential for growth and development of nearly all life- both plant and animal. About 1.4 - 2.3 grams are found in average adult with a recommended intake of 15 grams advised by the World Health Organization (WHO). In different forms, zinc is beneficial to life and in the form of zinc oxide is used as a nutritional supplement. It is not harmful to the environment and does not pose any threat to human.

Besides, it is 100% recyclable with less energy required to process it for use in corrosion protection. It could serve as the ultimate material to protect our state's structures in the parks, waterways, airports, etc. The following are few advantages of the hot dip galvanizing over other methods of protection from corrosion:


 * Hot dip galvanizing enjoys a low initial cost advantage over many other corrosion protection techniques. In addition, it is less labor intensive compared with other corrosion protection methods.


 * In rare cases where hot dip galvanizing has a higher initial cost than other corrosion protection techniques, it is more cost effective in the long term since it is durable with less maintenance needs. Because the protected materials are metallurgically bonded to the metal it protects, it offers superior resistance to abrasion and water and general mechanical damage in transport, erection and service.


 * Hot dip galvanizing coatings enjoy a high life expectancy of up to 45 years even in severe coastal and urban environments. In addition, this life expectancy and performance of the protected metal are easily predictable.


 * Hot dip galvanizing process is simple, straightforward and closely controllable. The coating thicknesses are regular, predictable and easily specifiable. This enables precision during usage and design resulting to quality results.


 * Implementation of corrosive protection is readily faster with hot dip galvanizing thereby providing a way to reduce project time and government money. A fully galvanized protective coating can be applied in few hours compared to a proper four-coat painting that requires up to one week. Hot dip galvanizing does not require any further site preparation, painting or inspection. Once erected, cladding can begin immediately, thus accelerating the construction program.


 * Inspection of hot dip galvanized coatings are assessed readily by eye, and simple non-destructive thickness testing methods can be used without the complexity usually used in other protection techniques. corrosion protection
