Cut to the size of steel products is very easy and there are different types of sheets used as raw materials in various industries such as petrochemicals. The black metal sheet has holes when it is raw and interestingly plays the role of raw material in the production of other sections such as profiles and pipes. The production of boards uses different standards. Therefore, the product is offered to the market in different sizes. In the iron and steel industry, sheets are produced by cold or hot rolling, while sheet metal is mainly produced by hot rolling. As these plates are placed in an oven at high temperatures, the color of the plates becomes a little dull and dull, which is why they are called boards or hot-rolled plates. 
The production cost of boards is lower than other methods, and the heat in the oven produces a quality product; therefore, the use of whiteboards can be seen in many areas. There are two types of boards, general and industrial, each made using a different technology. For example, ordinary boards are produced with ST37 standards and are mostly used for sheds and buildings. On the other hand, industrial boards are widely used in dam construction, petrochemical, and other industries. Due to the low carbon content of the structure of this sheet, it is also called low carbon steel. Due to its softness, this steel profile is very flexible and ductile. The ST52 switchboard standard is included in the industrial switchboard group. The black sheets are thinner than the oil-bearing type, and to make them, the bed is heated to 1280 degrees Celsius. The st52 board is similar to the low carbon type st37, but due to the presence of alloying elements, the strength is higher even though it is negligible. This problem also reduces flexibility. 
black metal sheet cut to size
Metal sheets, especially black steel sheets are easy to cut and we can provide you with the specific size you want them. The ST37 board and the ST52 board are light in weight, high in strength, and suitable for a wide range of applications. The cut board is cut according to the customer's order using a guillotine cutting machine, plasma cutting, air cutting, etc. Black flakes made in this way are called carved black flakes. Since paper can be cut to size using this method, the use of cut black paper has become more common. Cutting boards are used to produce beams, joists, structures related to bridges, rebar, etc. After coarse rolling, the plate enters the final rolling step to reach a high temperature and completely remove its possible irregularities and defects in this step. The final roll line has 5 to 7 stands and reduces the plate thickness to 1.8 to 3 mm. Then they lowered the temperature of the plate to about 580 degrees and prepared it for the winding stage. Finally, the cooled sheet is wrapped like a spool and goes to various factories and markets. Although the thickness of the board is mostly 1.5 to 100 mm, the minimum thickness of the board produced by the profile and pipe factory that requires thinner boards is 1.2 mm. The weight of the board, and therefore the price of the board, is affected by this thickness. Knowing the specifications of the board, it is not difficult to understand the reasons for choosing this application. Blackboard or sheets made by hot rolling have been expanded in many areas with their reasonable price and good mechanical properties. The product is very economical and has very little circulation. For this reason, industrialists are interested in it and use it in their specialized manufacturing and manufacturing areas. 
black metal sheet with holes
Metal and Metal sheets, especially black metal sheets have many flaws and holes. Raw iron is produced by reducing and melting concentrates in steel mills. The second most common metal in the earth's crust after aluminum is iron. Iron tends to combine with oxygen is very high, so pure iron is not found in nature. The first iron structures were discovered in Egypt and Mesopotamia, making the people of this country the first discoverers of iron. In the beginning, iron was a precious metal, even more, expensive than gold. Unlike gold and copper, not all the inhabitants of the earth discovered iron at the same time due to different geographical conditions, and the American continent was the last place in the world where iron was found, with the migration of Europeans to the area. Of course, it should also be noted that the rich copper resources in the United States make it unnecessary for the inhabitants of the region to discover new metals. As pig iron production increases, the price decreases. This problem caused iron to leave the noble metal group. With the decline in iron production and the problem of tin supply, pig iron was used to make tools and weapons of war. Iron meteorites are mainly composed of alloys of iron and nickel and were used to build early metallic structures. Iron tools are very expensive to manufacture due to their rarity and high cost. Over time, people realized that heating ore with coal could produce pig iron. After this incident and the use of open furnaces, mankind took an important step in the production of pig iron. Iron is extracted from mines in the form of hematite, magnetite, zeolite, limonite, and siderite. Iron ore cannot be used directly. First, we have to process iron ore at the factory. 
black sheet metal galvanized
Galvanized steel sheets and metal sheets have many different varieties and alloys. The black metal sheet is the first product of the process. Steel sheet has good resistance to chemicals, is durable, has a long service life, and is also easy to clean. The steel sink is one of the most important inventions ever. Stainless steel (steel plate) is one of the most popular alloys used by almost everyone in the world. As mentioned, stainless steel is durable and shiny, easy to clean, and easy to reuse after prolonged use and wear. The steel plate has now become an integral part of the kitchen. Among them: cutlery, countertops, and sinks, were all made of steel. Appliances and equipment made of steel plates give a professional look to the kitchen. Steel appliances are used in every kitchen because of their compatibility and aesthetic appearance. If you want your kitchen to be a shiny environment of metal, tools, and accessories made of steel are the only materials that can make it shine. Best of all, steel sinks are cost-effective and can serve you for a long time. There are many reasons to choose steel. This metal has good cutting and shaping ability and can be changed to different sizes and shapes. Today, worldwide, this alloy is used in large quantities in the design of kitchens. 
Types of crude iron
white: If the molten iron cools rapidly, no graphite will form. Pig iron made in this way is called white pig iron and is used in steelmaking. The content of white silicon is low and the material is hard and brittle. gray: When molten iron cools slowly, the carbon forms graphite. The silicon on top of this iron, called gray pig iron, causes brittleness. half gray: Semi-gray pig iron has properties between the first two types and is used in the manufacture of steel and cast iron. 
black sheet metal price
The price of a black metal sheet is one the most reasonable in the market and this helps to produce many different kinds of long products such as galvanized steel sheets etc. In general, hot-dip galvanized sheet is made of two types of steel, 36A, and 1011A, both of which are mild steel and are used in most industries. 36A is easy to weld and the heat treatment process is strengthened. 1011A is high-strength, high-ductility steel commonly used in the manufacture of containers. Unlike cold-rolled steel, hot-rolled steel has a thinner surface that resists corrosion. Slabs used in construction vary from commercial types ST33 to ST52. The hardness of these plates will vary depending on the type of alloy used, the higher the percentage of carbon in the steel plate, the harder the steel plate. The board is manufactured at a high temperature at the factory. By hot rolling, when the plate temperature reaches 1280 degrees Celsius, it is rolled in a preheater and the lime is removed during the first and last rolling, and the thickness is gradually reduced. until it reaches 1.2 to 1.2 16 mm, then sold as a coil. 
To complete the hot rolling, it is usually necessary to perform a variety of work, such as reducing the weight of the spool, improving the mechanical properties, flattening the plate, and cutting the plate light and heavy. We have said that there are two production methods for switchboards, industrial switchboards, and ordinary switchboards, with different standards. The industrial version under the brand name ST37 and the general version under the brand name A516-GR60, 70, A285-GR C, A283-GR C, and ST52 are available.
black galvanized steel sheet
steel products such as Black galvanized steel sheets are of famous products in places with high humid percentages. If you look closely, you will see that many of the appliances we use at work, at home, games, etc. are made of different metal products. These products vary in manufacturing techniques, alloys from which they are made, colors, types of applications, and more. Galvanized sheet is one of the widely used products in steel mills, and their invention and production have led to major changes in various industries. Galvanized sheet is manufactured under a special technique called galvanization. 
This method, the first random invention, creates the properties of a battery by combining two elements in a solution with completely different electrical properties. This property was first discovered by a man named Dr. Luigi Galvani, who lived from 1737 to 17985. Dr. Luigi, who was not a scientist, encountered this phenomenon by accident, but after him, between 1745 and 1827, a scientist named Alessandro Volta conducted a lot of intensive research in the field, naming the resulting current as current. Through chemical reactions of selected materials. Along with this phenomenon, much research has been done on how iron products oxidize and corrode to prevent these destructive reactions in iron. Finally, in 1836, a French engineer named Sorel combined the results of these two sets of studies and came up with the phenomenon of galvanizing, the immersion of iron in molten zinc. Today, products made in this way are called galvanized sheets. The first factory to produce galvanized sheets was also established in England in 1850. Then, due to the expansion of the use of galvanized sheets and the increase in the demand for this product, other factories were established in different countries like the USA, and its production continued. In addition, the galvanized sheet is currently produced in a variety of colors and its use will increase day by day. 
GI steel sheet price
Galvanized Iron or in short GI is one of the steel sheet byproducts which is coated with zinc. As we said, galvanizing means dipping iron in molten zinc. In this case, a layer of zinc adheres to the iron surface. Due to the difference in electronegativity that exists between iron and zinc, zinc becomes the anode and the factor that causes oxidation and destruction of the ferrous metal, i.e. Fe, by choosing zinc instead of Fe, the iron is preserved or its corrosion rate is minimized. Therefore, the galvanized sheet is very resistant to corrosion. Note that in this reaction, in addition to the galvanic properties produced, a barrier is placed between the iron and the free air, which also has a small amount of moisture, ie. the same thin zinc plate, which in itself reduces the amount of iron oxidation and production. rust.
