Have you ever noticed the importance of black sheet in the industry? Since iron is one of the most vital and most consumed metals and even materials in the world due to its strength and favorable properties, it is used in combination with other metals in different forms such as sheets for various industries such as automobile manufacturing and construction. Black sheet is a widely used product in the category of hardware, which is used as an intermediate product for the production of iron industrial goods with direct consumption, such as: car parts, building profiles, tank tanks, etc. For this reason, it is important to check its existence, use and properties, along with its types and effective factors, to determine the price of black or iron sheet for the relevant industries.
What is a black sheet?
Steel sheets are mainly prepared by hot and cold rolling methods, the products obtained from cold rolling include oiled, colored and galvanized sheets, and in the hot rolling mode, products are made in the form of sheets, rolls in simple types of construction, anti-wear and ribbed. .
In the production process of black sheet, the steel is placed at a temperature higher than the recrystallization temperature of the steel. In thicknesses above 1.5 mm, the price of black sheet increases. This product is available as a smooth and polished sheet, but it is produced with a lower surface quality than the cold sheet, and of course it is thicker, which sometimes requires polishing for use. The price of black sheet is lower than cold sheet, including oily sheet, as a result, they are used for different applications where appearance is less important. It may be interesting to know that the reason for using the black adjective for this sheet is the matting of its surface during the high temperature production process.
Black sheet can be divided into different types in terms of application, composition of materials and its appearance. In the following, we will examine the types of black sheet based on appearance:
Rolled black sheet, coil or coil, in which the width, depending on the thickness of the product, which is between 1.5-15 mm, in sizes 100, 125 , 150 and 200 cm and its length is unlimited.
The black sheet of fabric or sheet whose thickness is 15 mm or more can be purchased in any size, but dimensions such as 2000 x 1000, 2500 x 1250 and 6000 x 1000 And 1500*6000, 2000*6000 and 2000*12000 are widely used.
