Zinc is one of the metals used in steel sheets, especially black steel sheets. Iron is the number one metal used in steel so other materials should be added to it. With a coating of 0.55% aluminum, 43.5% zinc, and 1.5% silicon, the product is more durable than pure zinc-coated steel of the same thickness and can be used without additional protectio÷n in normal environments. 
In addition, this alloy is used as a substrate for some organic coatings. Corrosion of steel structures and their products costs millions of dollars every year. Zinc (Zn) coatings are the most effective and economical way to protect steel from corrosion, rust, and rot from many years of exposure to very harsh weather conditions. Galvanized steel (also known as galvanized steel) provides long life and high performance. As a result, manufacturers and consumers require high-zinc (Zn) sheets of coatings in durable and construction products. This coating should be checked at the deposition thickness stage. The coating is the amount of zinc coating on both sides of the steel plate, in gr/m2. There are two general types of galvanized sheets manufactured in factories: coil mold and fabric mold. Galvanized steel plate is used for various occasions, such as car manufacturing, parking lot, billboards, traffic signs, building materials, electronics industry, household appliances, and so on. X-ray fluorescence is an excellent technique for determining the elemental composition of steel products and the thickness of zinc (Zn) in steel coatings. A series of zinc-plated steel sheet samples were prepared to determine the thickness of the zinc. 
When analyzing the thickness of the zinc layer (Zn) on steel, there is no special preparation of the sample, only a metal plate is cut to fit the dimensions of the sample holder in the apparatus. In this study, an X-ray fluorescence spectrometer with an Rh-measured X-ray tube and a beryllium window was used for the analysis.
black iron steel sheet
The black iron sheet is the result of the hot rolling of billets. Steel plates are obtained by rolling ingots and ingots. The board is named because the elements and components of the board are melted during hot rolling, and due to this high temperature, the color of the product becomes dull. To make black iron plates, place the billets first in a preheater. After leaving the furnace at high temperature, an oxide layer forms on the bar. In the next step, a lift-off is performed to lower the temperature and remove the oxide layer. Then, in the next roll production process called raw rolling, the steel passes through the rollers several times in a back and forth path, thereby gradually reducing its thickness and increasing its length and width. Rough rolling is the step after shell washing. 
Rolling is one of the most important forming systems for various metals and alloys. In the next step of the production of black plates, after coarse rolling, they are transferred to the finishing rack. This line generally has 5 to 7 layers of shelves, which can increase the thickness of the black iron plate to 1.8 to 3 mm. In the final rolling process of hot rolling, mention may be made of the improvement of mechanical properties, light coils, flattening of plates, light and heavy cutting, etc., all of which are carried out according to need and need. After finding its final size, the black iron gradually cools and loses its temperature at about 900 degrees Celsius. Then it can be packed in rolls or cut sheets. The plate uses hot-rolling technology, which causes the raw material of the plate to melt at high temperatures. In this process, the plate is in a matte form, which is called a board by the market.
black steel sheet zinc
Zinc is one of the materials used in coating black steel sheet and other steel products. The use of boards varies according to quality, crude steel analysis, thickness and size. Products made by hot rolling are often used in the industry of large products because large products have different shapes, and the board has the ability to resize. 
Black sheet customers are the ones who are less important than strength when it comes to beauty and decor at an event. Below we will mention some uses of black iron:
- petrochemical
- dam
- tanker construction
- the construction industry
- The construction of heavy metal
- Car manufacturer
- put up
- shipbuilding
Like other types of steel, hot-rolled sheets have their own properties. Things like chemical analysis and mechanical properties are specified according to their grades. As mentioned in the first part of this article, for information on chemical analysis of boards, please refer to the DIN 17100 standard or its modern equivalent, BS EN 10025, which relates to chemical analysis. Detailed information on mechanical properties can also be found in the relevant tables in this standard. But in this connection, it should be mentioned that the mechanical properties of the board are optimized during the production process. When the temperature at which the recrystallization process is carried out is higher than 930 degrees Celsius, due to the compression of the steel during the rolling process, the formed steel crystals are first broken and then locked together, and sometimes dislocations containing impurity elements will form on the surface. The weight of the board is one of the important features that are necessary and necessary when buying a board so that customers can have a full understanding of the relevant board when buying and selling. When calculating the weight of the board, the length, width, and thickness of the board must be taken into account. 
black steel sheet zinc coated
Zinc is one of the materials used in the coating of black steel sheets. Use of black sheets:
- Closed or open structural profiles including cans, posts, Z-profiles, French, and frames.
- Steel profiles such as plate beams, studs, corners, guards ...
- Rail protection and traffic equipment
- Perforated plate, tape, and rebar
- Petroleum derivatives storage tanks and reservoirs
- Shipbuilding and other naval equipment and huge industries
And thousands of other products that can be made from boards of different thicknesses. The thickness of the board has always played a direct role in the price of the board. Some other harder boards are used in the production of pressure pipes and fuel tanks, etc. The standards are as follows: 1- SPHT2- SPHT3- SPHT4 SPHT. In addition, A285 plates with GR grades C (C) and 90 and A596 with GR classes 55 to 90 are also used for pressure tanks and high-pressure cylinders. Compared to cold-rolled steel sheets, hot-rolled steel sheets have thinner surfaces. The board is manufactured at a high temperature in the factory hot rolling. When the plate temperature reaches 1280 degrees Celsius in the preheating oven, it peels off during the preliminary rolling and post-rolling, and its thickness gradually decreases until it reaches 1.2. to 16 mm, and then it is sold in coil form. Sometimes, to complete the hot rolling process, it is necessary to reduce the weight of the spool, improve the mechanical properties, flatten the sheet and cut light and heavy. Because of the darkness of the product, it is known in the market as a blackboard. 
black steel sheet Zintec
Zintec black steel sheet is a sheet that is electronically coated with a thin layer of zinc on top to protect it from oxidation. Rich zinc coatings are used in various industries and sectors to protect steel from rust. For example, zinc-rich coatings are used in the highway and infrastructure, and automotive industries. These coating materials are improved compared to carbon steels coated only with functional organic coatings, such as (epoxy coating system, i.e. plastic coating system, i.e. white and crystalline combination). Zinc-rich coatings have been used as rust inhibitors and were first used for galvanized sheets in the automotive industry in the 1970s. Zinc-rich coatings provide less protection than a galvanized sheet but generally provide improved protection compared to organic carbon steel. Usually, in production and construction, the use of galvanized sheet metal components or the galvanized process is preferred. This process provides a guaranteed pure zinc-rich coating to protect the underlying structure of the material. However, zinc-rich coatings are suitable for repairs (also during production). Zinc-rich coatings may not protect the surface of the material like the galvanized sheet, but zinc-rich coatings may help prevent rust on the surface of the material. Zinc-rich coatings are also used in some military and industrial cases.
black steel sheet quartz
Quartz zinc is one of the other coated kinds of black steel sheets. Black steel sheet is a hot-rolled ticket product. In hot rolling, high gauge workpieces are passed through a series of rollers to achieve the desired final thickness. In hot rolling for sheet making, the temperature of the steel is typically above 1700 ° F (about 926 ° C), above its recrystallization temperature. At these temperatures, the steel is easy to shape so that the desired thickness can be easily achieved. The reason why the black sheet is called this is that soot and black oxides on the surface of the sheet due to the high temperature of the process cause the surface of the sheet to be black and rough. 
According to its production process, blackboard is a basic product that requires secondary processing to convert it to other sheets such as galvanized sheets. Therefore, the board has a black appearance due to the high temperature and soot applied during the production process. It is also easy to identify as no secondary treatment has been applied to it, which keeps it black. The main advantage of these steel plates is that the price is lower than other steel plates. This is due to the lack of protective coating of black plates compared to galvanized and oiled plates. In addition, the rough and dark surface also contributed to the lower price of this product. Among other reasons for the lower price of whiteboards, we can mention the simplicity of production and fewer manufacturing steps compared to other whiteboards. In addition, the high-temperature production results in a normalizing operation on the board after the hot rolling is completed, which is cooled in air, thereby removing its internal voltage.
black steel sheet quartz countertops
Because of the quality of Quartz coated sheets, this product is used for countertops in the kitchen as well. Black steel sheet is the main material of this product. Steel plate is a type of stainless steel alloy where carbon, nickel, manganese, and phosphorus are used in its structure in addition to iron to increase corrosion resistance and achieve more flexibility. The reason for the antifouling and anti-corrosion function is the presence of chromium. Due to its high strength and durability, the 304 steel plate also has a variety of applications in various industries. At the same time, steel alloys have been able to take the lead in the construction industry. 
Popular steel sheet alloys are widely used because of their relatively reasonable price and diamagnetic properties compared to other stainless steel. Type of stainless steel 4301. 1 and 4307. 1 are designated as class 304 and class L304, respectively. Type 304 is considered the most versatile and versatile stainless steel. It is sometimes referred to by its old name, 18/8, which is the nominal composition of Type 304, a derivative of 18% chromium and 8% nickel. Grade 304 austenitic stainless steel is capable of deep drawing. This feature has made 304 degrees widespread and used for things like sinks and planters. L304 stainless steel is a low-carbon version of 304 stainless steel. It is used to improve the weldability of large measuring parts. H304 is a high carbon version that can also be used for high-temperature applications. 304 stainless steel plate has excellent corrosion resistance in different environments and when exposed to different corrosive environments. Pits and cracks can occur in chloride-containing environments. Voltage cracks occur at temperatures above 60 ° C.
