- Applications of Galvanized Steel Sheet
Galvanized steel coil can be widely used in different applications after further processing, including:
1. Construction
They are often used as roofing, interior and exterior wall panels, the surface sheet of the 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.3. Transportation
It is mainly used as decorative panels of cars, decks 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.
Why Choose Galvanized Steel Sheet?
1. Cost-effective Solution
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.2. Wide Applications
GI sheet roll is easy to process for different purposes. It is widely used in construction, home appliances, automobile containers, transportation, etc.3. Easy to Transport
Compared to GI steel sheets, coils are easier to transport. In this way, it will save your shipping cost.
- Spangles on Galvanized Steel
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 the 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.
Galvanized sheet / plate can be cut, machined or welded by common methods used for regular steel, but adequate ventilation should be used to avoid inhalation of fumes when heated. Sheared edges are not galvanized and can be treated with a cold galvanizing paint to maintain protection if desired. 1/4″ to 1/2″ plates may have a 3/4″ hole present in two corners from the dipping process. All dimensions are before the galvanizing process.
- Differences Between Hot-dip and Electro Galvanized Steel Sheet
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 300 μm.
2. Resistance to Corrosion
The corrosion resistance of hot-dip galvanized coil is much better than that of an electro-galvanizing one. It is because of the thickness of the zinc layer and the adhesion between the base metal and zinc layer.
3. Appearance
The appearance of the electro-galvanized coil is more smooth and bright. While the surface of the hot-dip galvanized coil is rough and dull.
4. Applications
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.
- Hot-dip Galvanized Steel Sheet Production Process
- Clean the grease, dirt, and paint on the surface of the steel coil. The coils need to be uncoiled and welded for continuous processing.
- Rinse off the cleaning solution.
- Put into an acidic solution to remove mill scale.
- Wash off the pickling solution.
- Dip the steel into the molten zinc bath and hold for a while to be galvanized.
- Cool down and roll up the steel into coils for sale.
