GI Steel Sheet profile:
Galvanized sheet or coil is defined as a carbon steel sheet coated with zinc on both sides. Continuous hot dipping, or electro-galvanizing are the two processes used to produce galvanized sheet and coil. Generally speaking, the hot dip process consists of passing the steel through a bath of molten zinc. The electro-galvanizing process consists of the application of zinc by electrolytic disposition. The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer.
A zinc coating is one of the most effective and economical methods of protecting bare steel from a corroding environment. The zinc not only serves as a barrier between the steel and the environment, it will sacrifice itself to protect the underlying steel sheet. Sacrificial, or galvanic protection occurs when two dissimilar metals are in contact and coupled with water and oxygen. Zinc corrodes preferentially to the iron in steel. This protection prevents corrosion of the steel at areas not covered with zinc. Thus, the spread of corrosion from cut edges, drill holes, etc. is minimized.

Q: How It's Made
A: One of the most common ways of making steel resist rust is by combining (alloying) it with a metal that is less likely to corrode: zinc. When steel is submerged in melted zinc, a chemical reaction permanently bonds the zinc to the steel. Therefore, the zinc isn't exactly a sealer, like paint, because it doesn't just coat the other metal; it actually permanently becomes a part of it. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel.
This process, known as hot-dipped galvanization, is one of the most common methods of making galvanized steel, but it's not the only one. Continuous sheet galvanizing runs a steel sheet or wire through molten zinc; it's also a form of hot-dipping, but leaves a thinner layer of the protective metal. Steel can also be painted or sprayed with zinc, although neither method creates the strong bond that hot-dipping does. Electrogalvanizing or electroplating uses electricity to create the bond between the two metals, which results in relatively thin layer of zinc.
The degree of galvanizing is usually described as the zinc's weight per surface area rather than its thickness, because this gives a better representation of how much metal has been applied. Steel often gets galvanized after individual parts have been formed, such as braces, nails, screws, beams, or studs. Continuous sheet galvanizing is often done before the metal is used to create products, however, and can withstand some bending and forming without flaking.
Q: Benefits of Galvanization
A:Zinc protects steel in two ways. First, it is highly resistant to rust; iron, a major component of steel, reacts very easily with oxygen and moisture and will eventually disintegrate. The layer of zinc on the surface prevents those elements from reaching the steel so quickly. It also develops a patina — a layer of zinc oxides, salts, and other compounds — that offers further protection. Zinc is also extremely durable and scratch resistant, and has a satiny appearance that many find attractive.
Q: Uses
A: Galvanized steel can be found almost everywhere. Many individuals live in steel frame houses, and buildings are often made with galvanized steel roofs. There are multiple steel parts in cars that help protect them from the weather, and it's used in many marine applications due to its ability to withstand the salt and the elements. Besides being inexpensive, durable and effective, this metal is also popular because it can be recycled and reused multiple times.
Q: Disadvantages
A:There are relatively few disadvantages to galvanization, but it's not a good method for protecting all steel items. Some objects cannot be hot-dipped, often because they are too large or too small, and other forms of galvanizing often are not as protective and long-lasting. Eventually, the zinc will be corroded, although how long this takes depends on the thickness of the coating and the environment. Galvanized steel has a much shorter lifespan when it's regularly exposed to rain or seawater.
