Steel alloy consists mostly of iron and when the iron comes in contact with oxygen to form iron oxide or rust. Steel is used in a number of things today. It is used to construct buildings, infrastructure, automobiles, ships, machinery, equipment and more.
There are many ways to prevent the steel from corrosion such as electroplating and zinc coating. Galvanizing is one option that is widely used for industrial purposes.
Painting is another way to prevent rust and is used mostly on cars, appliances and sometimes even on the building.
Metallizing is another expensive process in which zinc is sprayed onto the steel. Get more information about the galvanization process via https://ecofittingvalve.com/รายละเอียดสินค้า-4972-reducing-socket-galvanized-steel-แบบเกลียว.html.
Galvanizing is one of the most common ways of preventing corrosion and is widely used today. But sometimes when galvanizing objects, especially at the surface is scratched, zinc or tin is not attached to, it seems, holes or joints of an object.
The only solution to this is a hot-dip galvanizing. Hot-dip galvanizing is done with zinc bonds to steel at a molecular level. This allows the coat to migrate to cover the entire surface including scratches, joints and even holes.
Hot-dip galvanizing includes not only steel with zinc coating, but it involves a process in which there are four layers used in covering the steel base.
The first three layers that are used are zinc-iron alloy and the fourth is a pure zinc. Zinc-iron alloy increases the strength of steel and the final layer of pure steel to prevent corrosion forms.
Problems with paint and other costs occur when the object is coated and will be scratched or damaged. The hot-dip galvanizing creates a metallurgical bond between zinc and steel with no chance of rust.
