Galvanized steel coil can be widely used in different applications after further processing, including:
They are often used as roofing, interior and exterior wall panels, the surface sheet of balcony, ceiling, partitioning walls, windows and doors, gutter, barn, sound insulation wall, etc.
2. Home Appliances
GI coil is widely applied to home appliances, such as the base of washing machines, water heaters, refrigerators, microwave ovens, etc.
It mainly used as decorative panels of cars, deck of trains or ships, containers, road signs, etc.
4. Furniture, such as wardrobe, locker, radiator, lampshade, table, bed, bookcase, shelf, etc.
5. Other Uses, such as post and telecommunication cable, highway guardrail, billboards, etc.
Compared to GL or color coated steel coils, the galvanized coil is the most cost-effective solution but with similar features, such as great corrosion resistance, good appearance, etc.
GI sheet roll is easy to process for different purposes. It is widely used in construction, home appliances, automobile containers, transportation, etc.
Compared to GI steel sheets, coils are easier to transport. In this way, it will save your shipping cost.
Spangle is formed during the hot-dip galvanizing process. The size, brightness, and surface of spangles mainly depend on the composition of zinc layer and cooling method. According to the size, it includes small spangles, regular spangles, big spangles, and free spangles. They look different, but the spangles almost will not influence the quality of galvanized steel. You can choose according to your preference and purpose.
According to the processing method, we divide galvanized steel into the following categories:
As the name implies, hot-dip galvanizing is immersing the cleaned iron sheet into the molten zinc bath at about 500 degrees to form a zinc layer. It is the most commonly used method. It has some advantageous features:
1) The entire steel surface is uniformly covered with a zinc layer, even the corners, hollows, etc. so that the steel sheet is fully protected.
2) The cost of hot-dip galvanizing is cheap.
Electro-galvanizing is a process of applying a layer of zinc to steel through electroplating, with a saline anode and steel conductor. It is able to enhance the corrosion and heat resistance of steel. Also, it makes steel sheets more good-looking.
1. Thickness of Zinc Layer
Generally, the thickness of the electro-galvanizing layer is 5~15 μm, and the hot galvanizing layer is often more than 35 μm, or even as high as 200 μm.
2. Resistance to Corrosion
The corrosion resistance of hot-dip galvanized coil is much better than that of electro-galvanizing one. It is because of the thickness of the zinc layer and the adhesion between the base metal and zinc layer.
The appearance of electro-galvanized coil is more smooth and bright. While the surface of hot-dip galvanized coil is rough and dull.
Hot-dip galvanizing products are widely used in transportation, building, communication, electric power, energy, automobile, petrochemical, home appliances, and other industries. While the electro-galvanized coil is more suitable for small parts, or indoor environments, etc.
The galvanized steel coil prices mainly depend on the thickness steel coil, the thickness of zinc layer, etc. When you choose GI steel rolls for sale, you need to pay more attention to the quality instead of the price only.
