Steel sheet is one of the profiles used for various industries such as automobiles, shipbuilding, household appliances, etc. It is applicable. This product is produced using slab rolling. Mobarake steel in Isfahan, Aksin steel factory in Ahvaz and Kavian steel in Gilan are among the steel sheet producers. In this article, we are going to introduce you to the types of iron sheets and the use of each one.
Metal sheets with a thickness of about 6 mm are produced. The production method of these products can be with the help of hot or cold rolling. Iron sheets are designed and produced in such a way that operations such as riveting, shaving, folding, pressing and cutting can be done on them. In relation to what this product is used for, we have to deal with the types.
In fact, what is available as sheets in the market has different types that are named on them. Each of these steel sheets has a specific application.
Types of steel sheets based on their names at the time of production include the following:
American ASTM standard sheet
sheet with Russian Goose standard
There are different types of iron sheets, which include:
Acid wash sheet
It is one of the types of acid-washed steel sheets that are washed with acid. The type of acid used for these steel sheets is hydrochloric acid, which destroys the iron oxide layer. Acid washing sheet is the raw material for the production of oil sheets, which we will explain below. Of course, acid washing varnishes are also used for the production of car chassis and rims.
This product is also used for submarine and shipbuilding facilities, making oil and gas pipes. Also, acid-washed sheet is the basis of oil sheet production and is used to make car rims and chassis
The oiled sheet is produced based on the cold rolling method. In the production process of this product, rollers at the top and bottom determine the thickness of the sheet. Also, this roller prevents oil sheet from bending. Tensile force and pressure are two important factors for the production of oil sheets.
In the next step, acid washing method is used to make this product. This is done to remove the oxide layer of the sheet. In order for the sheet not to have thermal stress, it is made resistant in the heating stage to reduce the heating temperature of the sheet. Finally, the sheet is cooled.
Among the features of the oil sheet, we must say:
This product is used for the production of galvanized sheets, the production of household appliances such as gas stoves, or the coating of products such as refrigerators. Oil sheet is also used for the production of pipes.
Among other iron sheets, we should mention the ribbed type. This product has a smooth and polished surface and it is highlighted with the help of a roller. The ridges on the ribbed sheet are geometrical and regular shapes that give it a beautiful appearance. In order to produce ribbed sheets, oil sheets or any other smooth sheets are changed with the help of a treading machine.
The treading machine is in the form of a roller that is placed on the steel sheet with great force and creates a shape on it. These products are used for the following:
One of the types of widely used steel sheets is called black sheet. You might think this profile is black. But in fact it is not like that and only its surface is not smooth and polished to reflect the light. For this reason, it looks darker than other sheets. Hot rolling method is used to produce this type of metal sheet.
To produce black steel sheet, first the steel ingot is heated to the melting temperature so that it becomes soft. Then it is slowly spread on a wide and flat surface to form a rectangular cube with a long length. When the molten material of the steel ingot takes shape in the mold, cold water is poured on it to cool and harden. They put it back in the oven to reach the right temperature. This time the heating of the black sheet is to increase the flexibility for rolling. In the last step, the thickness of the black steel sheet is brought to the standard size.
Black sheets are used for the production of car bodies, car floor sheets, the production of seamed pipes, the production of profiles, the use of tankers, and the use of shipbuilding.
Another type of metal sheets are produced to prevent oxidation and corrosion. Although these products are expensive for industrial use, they are suitable for many jobs and environments that are exposed to acid and water due to a waterproof coating. Currently, the cheapest solution to prevent iron sheet from oxidizing is galvanizing.
To produce these products, oiled sheets are used as a base sheet. The production method is that first they melt the oily steel sheets in the furnace and then pour it on a special mold according to the standard thickness of a metal sheet.
Finally, both sides of the sheet are covered with a galvanized glaze. These products are resistant to corrosion, scratches and impact.
Among the applications of galvanized steel sheets, we can mention their use for producing water pipes, making cabinets, using them for water storage tanks, and producing shed roofs.
Another type of colored steel sheet is produced using galvanized sheet. The only difference between these two products is the use of electrostatic color coating for the color sheet. This product is available in 15 different colors. In the production process of this type of metal sheet, first the coil of galvanized sheet is cleaned and degreased. Then they pass a roller over it to make it smooth and uniform. They wash the sheet again to make it clean. After drying, the sheet is painted.
This steel product is painted using a powder polymer base paint that is sprayed on the top and bottom surfaces of the sheet. Then it is put in the oven to bake the color on the sheet.
In the next step, they use other colors such as polyester, epoxy, polyvinyl chloride or polyurethane. According to the manufacturer’s choice, one of these colors is poured on the sheet using a roller and it is taken back into the oven to increase the color resistance.
Among the applications of colored steel sheet, we can mention its use for the production of shed roofs, pavilions and gables. Also, this profile is used for the production of household and office appliances, manufacturing of cooling and heating equipment, use in metal industries, use in the transportation industry such as the cabin of a car and heavy machine.
Another type of metal sheet is an alloy that uses several metals to produce it. These products have different shapes and are divided into two categories: cold rolled and hot rolled. Metals such as brass, bronze, pewter or iron are used to produce steel alloy sheet. Most of these alloys are expensive, and for this reason, the alloy sheet is considered one of the most expensive sheets in the market.
This product is available in the market in two forms, roll form and sheet form. Among the uses of alloy sheet, we can mention the construction of ships or marine equipment and the aircraft industry. Also, this product is used for petrochemical, oil or gas industries and the production of fuel tanks.
Another type of steel sheet in the market is made of stainless steel metal. This product has features such as rust resistance, recyclability and high durability. All steel sheets available in the market are not the same and have different quality based on the amount of steel and chrome metal used.
The reason for using steel to produce steel sheet is to increase the mechanical and thermal properties of this product. Also, this profile has high malleability and does not rust or corrode. Of course, it goes without saying that steel metal sheets are not produced in Iran. What exists in Iran is all imported from countries like China, South Africa and Taiwan.
Among the applications of steel sheet, we can mention the manufacture of various household appliances and food industries. Steel metal sheets are also used to build the body of vehicles such as cars, planes or trucks. Another use of this product is to make all kinds of tanks and kitchen utensils such as spoons and forks.
Among other types of steel sheets, we should mention stainless steel products. In the production of this product, a small amount of iron, carbon and other alloys are used to produce stainless steel sheet. A lot of carbon is used in the production of this product.
This product has different types. Among them are 300 and 400 steel sheets, which are different in their use. All stainless steel metal sheets are acid-proof and coated. Stainless steel sheet is used to make household appliances, food and pharmaceutical industries.
Among the features of this product, we should mention its beauty, resistance to moisture and corrosion. These sheets are also recyclable and stainless steel.
The most important application of this product is for making household appliances, making ship parts, producing car bodies, trucks and airplanes, and petrochemical industries.
