Today, steel plate are manufactured and supplied according to German, US and Russian standards, which we will discuss. The first is the DIN standard in Germany, which is the most common standard for Iranian steel. The second is the American ASTM standard, which is less used than the previous two standards for the production of steel plates, and finally the Russian standard. Steel sheets have different carbon ratios, so they have different properties and have a special name. For more information on the size of the steel plate market in 2021, visit our website.
Different types of steel plate
Cold rolling is one of the methods used in the preparation of steel sheets, and the process is not very difficult. Here, the iron ingot, which is to be turned into a steel sheet, is placed between two rotating cylinders up and down, and begins to deform by applying pressure from them and by the continuous up and down movement of the two cylinders. . It should be noted that before starting this operation, the iron ingot should be washed with acid, which should be thoroughly cleaned if there is an oxidized layer on the surface. Cold rolled steel sheets are generally of higher quality than hot rolled steel sheets.
The white steel sheet is the result of this process. Hot-rolled steel sheets, unlike the previous method, are deformed and shaped using a temperature of about 1400 degrees Fahrenheit. In Latin, this type of steel sheet is also called hot roll or hot roll. Steel sheets made in this way are between 1.16 and 5.16 inches, and if they are thicker than 6 inches, they are called plates. Black sheets and galvanized sheets are called steel sheets produced by this method. Acid washed, galvanized, colored and rolled steel sheets Acid washing is a process that removes impurities and oils from a layer of black steel produced by hot rolling, as mentioned above. The substance used in acid washing is hydrochloric acid.
After washing with acid, the metal surface looks cleaner and shinier, and even resembles a slightly oiled layer. The galvanized sheet is also made of cold-rolled steel sheet. To produce a galvanized sheet for a long time, a few microns of zinc metal is sprayed on it to make it more resistant to rust. It is important to know that during this process there is an electrochemical movement between iron and zinc, so iron acts as a cathode and zinc as an anode. For this reason, galvanized steel sheets still do not rust, even if there is a groove or scratch on the surface. These sheets are produced in different colors and are used on the facades of salons and upholstery due to their strength and durability. The shutter layer is essentially the same as a galvanized sheet or colored sheet with a different design. In fact, they are very similar in thickness, length and width. The only difference is the price, and it is clear that colored and rolled sheets have a higher price than ordinary types. For more information on steel plate price visit our website.
