Product Description

Mild Carbon Steel Galvanized Steel Pipe Tube For Steel Structure Warehouse



Product Description:

Stainless steel prevents corrosion similar to galvanization, however, galvanization of steel is far more economical. If you are working with a budget, you will want to look into galvanizing existing stock versus using more exotic materials.


Hot dip galvanizing is a straightforward process. The steel is first chemically cleaned or cleaned via sandblasting. Then, the steel is pickled to remove mill scale. A flux, often zinc ammonium chloride, is applied to the steel to prevent flash rusting. Following this step, the steel is dipped into a molten zinc bath. The molten zinc bonds to the iron in the steel, thus creating a protective coat on each surface of the steel. The zinc-coated steel is cooled (quenched) in a cooling tank and re-stenciled once cooled. The outer layer will not crack, flake or peel when a steel sheet is spun into a finished part.

Benefits of Galvanized Steel:
Galvanized steel is most commonly used for construction. Galvanizing achieves the following two lines of defense:
1. Protection from Oxidation
Galvanizing provides additional protection from corrosive substances in the atmosphere. The zinc is more reactive than the iron in steel, so atmospheric oxygen will first react with the zinc rather than the iron, thereby oxidizing the zinc coating and delaying corrosion to the underlying steel.


2. Sacrificial Layer
The zinc coating provides a physical barrier that serves as a sacrificial seal. As a result, any damage from potential impact, scratching, drilling and cutting will affect the outer zinc barrier first, leaving the underlying steel protected.
