We are a leading Manufacturer, Traders and supplier of galvanized steel sheet. Galvanization is the process of applying a protective zinc coating to steel or iron in order to prevent it from rusting. The term is derived from the name of Italian scientist Luigi Galvani. Galvanized iron (GI) sheets are steel sheets which are basically coated with zinc and include a range of hot dip galvanized and electro-galvanized steel sheets. Zinc weathers at a very slow rate, so the coating generally has a long life. Zinc has a greater electro-negativity than iron and hence provides cathodic (or sacrificial) protection to the steel. This results in the zinc corroding in preference to the steel if the coating is chipped or damaged to expose the base metal. Besides acting as galvanic protector, The other functions of the zinc layer are as follow:

To retain the steel intact with its full initial strength.
To provide the surface a more pleasing appearance.
To increase the life of any suitable organic finishing system applied over it.
To protect the steel from corrosive attack in most atmospheres, acting as a continuous and lasting shield between steel and the atmosphere.

Galvanized GI Steel Rolls & Plates & Coils
Whatâ??s the difference between galvanized GI steel coils and plates?

I. Definition
Galvanized GI Steel coil and galvanized sheet are galvanized steel. The galvanized coil is a continuous hot dip galvanized coil in the production process. While galvanized sheet is a single hot dip galvanized sheet in the production process.

2. the production process
The production process of galvanized coil and galvanized sheet is different.

The production process of galvanized coil generally includes multiple processes such as coil heating, hot dip galvanizing and shearing into coil.

The galvanized sheet is generally the zinc alloy coating through the hot dip technology directly coated to the surface of the steel plate.

So the production process is relatively simple, the process difficulty is relatively low.

3. material thickness
The material thickness of galvanized coil and galvanized sheet is also slightly different.

Generally speaking, the thickness of galvanized coil is relatively thin. We mainly use it for the production of cold rolled, coating and other thin steel products.

The thickness of galvanized sheet is relatively thick. We mainly use it in the manufacture of glass fiber reinforced plastic, automotive panels, roof panels and other steel products requiring strength and corrosion resistance.

4. Advantages and Disadvantages
Both galvanized coil and galvanized sheet have their own advantages and disadvantages.

The production cycle of galvanized coil is short, the process is simple, and it is suitable for the production of low thickness and high precision steel products.

The galvanized sheet has the advantage of hardness, corrosion resistance, wear resistance and other multiple properties.

However, the production process of galvanized sheet is time-consuming and laborious, and the production cost is relatively high.

5. Application fields
The application areas of galvanized coil and galvanized sheet are also different.

Galvanized coil is usually used in the production of home appliances, building materials, auto parts, pipes and other high-demand steel products.

The galvanized sheet is mainly used in automobile manufacturing, construction engineering, petroleum, chemical and other industries.

In addition, because of the good corrosion resistance of galvanized sheet, it is also widely used in Marine engineering, railway, bridge and other fields.

Hindalco's cold rolled coils are precision-finished to match international standards. They have good shape, high tolerance, versatility and blemish-free surfaces. They are used in commercial and general engineering applications such as bus bodies, cladding and fan blades. The company meets the demands of its ever-growing clientele with continuous upgrades and process improvement.
