Probably the most important reason for the difference in galvanized sheets is the difference in the manufacturing method.
Sheets made with different methods will have different properties and end up with different uses.
This condition can even affect the appearance of the galvanized sheet and can cause this difference.
In general, the galvanized sheet is manufactured in several ways, and the final product will be classified as hot-dip galvanized or hot-dip galvanized.
Immersion method in the zinc bath
As the name of this method suggests, steel plates are placed in pools of zinc metal.
In this method, the temperature of the zinc metal is usually very high, reaching 400 to 500 degrees Celsius.
For this reason, the galvanized sheet produced by this method is also called a hot-dip galvanized sheet.
Since the electroplating process in this method is carried out at a high temperature, it will cause a reaction between the steel plate and the zinc metal.
This results in zinc penetrating the surface layer of the steel sheet and providing greater resistance to corrosion and rust.
In this method, the thickness of the zinc layer on the surface of the galvanized steel plate is obviously not controlled, and the surface thickness on both sides of the steel plate is the same.
Electrolysis
Another important method of making galvanized sheet is alcohol electrolysis.
In this method, each steel plate and zinc metal are placed in solution and act as cathode and anode.
In this way, a zinc metal coating is formed on the surface of the steel plate.
In this method, the thickness of the zinc placed on the surface of the steel plate can be controlled, and even this thickness can be considered as the difference between the two sides of the steel plate.
Galvanized sheet produced in the electro galvanizing process is called cold galvanizing because it is carried out at ambient temperature.
Spray zinc solution on the surface of the plate

Another method used to make galvanized sheet is to spray zinc solution or galvanized solution on the surface of the steel sheet.
The galvanized plate produced by this method is also called a cold galvanized plate because the solution is prepared at ambient temperature and sprayed on the surface of the plate.
The solution used in this method may have an aqueous base or an acid-base, depending on the standards followed by the manufacturing company.
By this method, the thickness of the zinc can be determined to a large extent.
Depending on appearance
The next difference between galvanized sheets is their appearance.
All galvanized sheets generally have a shiny appearance and a polished finish.
However, depending on how they are produced, the gloss or smoothness of their surfaces is different.
In general, sheets produced using the dip method have a matte surface and have a lower level of polish than cold-dip galvanized sheets.
The reason is the high-temperature tolerance in the production process.
On the other hand, due to various reasons, including the cooling rate and the type of galvanized sheet after the final production, small shapes, called flowers, may develop on the surface.
In some cases these flowers can be very large, this type of sheet is called a large flower galvanized sheet.
Sometimes these flowers are smaller and the final sheet will be referred to as a "small flower" galvanized sheet.
Of course, as we mentioned, these flowers are due to the cooling rate and the type of plate and are usually not indicative of the quality of the galvanized plate.
Standards-based
Different companies use different standards when producing galvanized sheets.
Using different standards will result in differences in the properties and application of the final galvanized sheet.
There are many standards for the manufacture of these types of panels, some of which are international and some of which are national.
But usually many of them are interchangeable.
galvanized steel sheet specification
One of the most common standards is ASTM, which is used worldwide.
Differences in standards naturally result in different thicknesses of zinc, and therefore differences in density and final weight for these types of plates.
Properties of galvanized sheet
Galvanized sheets have many suitable properties so they are used in a variety of applications.
One of the most important properties of galvanized sheets is their high resistance to rust and corrosion.
Therefore, these plates can be used in places with high humidity or frequent contact with water.
In addition to these items, galvanized sheets are also reasonable.
This problem makes the choice of galvanized sheet preferable to other sheets with this feature.
Of course, the application type is also very helpful in selecting these tables.
The next important feature of galvanized sheet is its long service life.
Galvanized sheets can last for many years due to the galvanized coating on the surface of these sheets to prevent rust and corrosion of the sheets.
On the other hand, if the galvanized parts of these plates are damaged, these parts can be repaired.
The galvanized plate is also at an appropriate hardness level and is not easy to wear.
Although this feature is largely related to the base steel plates used in these plates.
How to identify galvanized sheet
There are many ways to identify galvanized sheet, but the most reliable way is to buy this sheet from a reputable seller or website.
In this case, you want to make sure that the galvanized sheet is of good quality.
Another way to identify galvanized sheets is to examine the appearance of these sheets.
These plates have a polished and shiny finish and in many cases large and small flowers can be seen.
These plates are more suitable in terms of price than other plates with similar properties such as stainless steel or stainless steel.
They are of course more expensive than ordinary steel, which is why they use a zinc layer on the surface.
Another way to identify them is to examine the surface layer and identify the zinc metal present in this section.
Galvanized sheet material
As we said, the galvanized sheet is made by applying galvanized or zinc coating to the surface of the steel sheet.
But usually, these coatings are placed on plates produced by cold rolling or oil plates.
Since the plates or boards produced in the hot rolling process do not have a smooth and polished shape, they are not suitable for the production of galvanized sheets.
Therefore, they are not used as galvanized substrates.
It is of course also possible to put the board into the cold rolling process, and after the necessary process add a galvanized coating to it, which rarely happens.
Galvanized steel sheet is used in many different areas around the world for their important anti-rust properties.
These sheets can be used directly or converted into secondary equipment.
In the following, we bring you some of the most important cases of direct and indirect use of these worksheets.
galvanized steel sheet thickness
The most common uses for galvanized sheet include the following.
- Roof construction and use of some walls in large places such as greenhouses
- Construction of large tankers and tanks for water or other liquids
- Craft a variety of household and kitchen tools
- Make galvanized pipes, profiles, and other parts
- The purpose of these sheets is to produce colored sheets
- for the automotive industry
- Manufacture necessary equipment for the agro-industry
- Production of some construction metal fittings and materials such as rabies
- for the production of large billboards
Steel sheets are coated with zinc metal in a process called galvanizing, resulting in galvanized sheet.
This sheet has many properties that make galvanized sheet one of the most widely used steels.
Zinc metal protects the plate against environmental factors such as moisture, corrosion, and oxidation and thereby increases the plate's lifespan.
This sheet is used in many industries such as automobile manufacturing, construction, agriculture, etc.
The thickness of the zinc metal used to cover the galvanized sheet depends on various factors such as the application of the sheet, where it is used, the chemical composition of the steel, etc.
The strength of the galvanized sheet is directly related to its thickness, which also affects the price of the sheet.
Galvanized sheet is produced by various methods.
Two methods of cold rolling and hot rolling are generally used to produce galvanized sheets, but the most commonly used production method is hot rolling.
There are different types of galvanized sheet, each of which is used for specific purposes within industry and construction.
Each of these types of plates is produced by a special method.
To make it easier for you to understand the types of galvanized sheets, we have categorized them according to production method, design, appearance and type of coating.
Galvanized sheet by production method:
Hot-dip galvanizing
This galvanizing method is one of the old ways of dipping steel products into a bath of molten metal.
Zinc metal adheres to the surface of the steel plate and forms a thick coating.
This coating increases the plate's durability and resistance to corrosion and rust, making the plate a cost-effective product.
galvanized steel sheet corrugated
After the plate is taken out of the molten metal pool, the product is dried and divided into three categories: no flower, small flower, and large flower.
Electro-galvanized
In the electro galvanizing method, a zinc sulfate (ZnSO4) or cyanide solution and electricity are used to form a coating on the steel plate.
In this method, the galvanized sheet has a thinner thickness and a smoother surface than the thermal method.
Thermally formed coatings are thicker than electro galvanized, making painting more difficult.
For this purpose, plates produced by the electro galvanization method are used in the automotive industry.

The panels are used for the construction of pitched roofs for sheds, houses, and production units.
Coloring pages
Colored sheets of this type are produced at all factories in 1000 and 1250 mm widths.
In the manufacture of this product, a colored polymer coating is applied to the surface of the galvanized plate, which increases the plate's resistance to damage from environmental factors.
galvanized steel sheet roofing
Roller shutters
Roller shutters differ from regular shutters, which are considered a type of roof panel.
The thickness of this plate is typically between 0.
4 and 1 mm and will not dissolve many loads.
Roller shutters are used for the construction of door frames in production workshops and shops.
Schedule
This type is considered a subset of roofing sheets, and its thickness is usually between 0.
