Galvanized Steel Strip
Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot-dip galvanizing.
Galvanized steel is among the most popular steel types because of its extended durability, having the strength and formability of steel plus the corrosion protection of the zinc-iron coating. The zinc protects the base metal by acting as a barrier to corrosive elements, and the sacrificial nature of the coating results in a long-lasting and high-quality steel product.
This versatility makes it applicable to a variety of projects and industries, including agriculture, solar, automotive,construction, and so on.

steps in the galvanizing process
The steps in the galvanizing process are as follows:
* The steel is cleaned in a degreasing solution
* After being cleaned, the steel is pickled by being lowered into a vat of diluted hot sulfuric acid
* The steel is then fluxed in an aqueous solution (typically zinc-ammonium chloride)
* After the flux, the steel is galvanized through immersion in a vat of molten zinc
* Afterward, the steel is inspected for consistency and a complete coating
