There are many different kinds of steel products in the market. Coated sheets and steel bars are among those favorite steel products that we easily calculate the prices per kg. Steel sheets are usually covered to protect and create a beautiful appearance. The main types of coated plates are galvanized plates, galvanized plates, colored plates, and tinned plates. Galvanized sheets can be considered the most important coated black steel sheet . Galvanized sheet is widely used in various industries. The plate is resistant to corrosion due to the presence of a specific thickness of zinc metal on the surface. Zinc metal appears as a sacrificial metal next to iron, which is the base of the steel plate. This property is affected by the potential of these two metals, and since the potential of zinc metal is lower than that of iron, it provides iron protection. The manufacturing method for galvanized sheet
Immersion In order to produce galvanized plate, it is first necessary to produce a cold plate of a certain thickness. Cold plates are produced by pickling and hot rolling. The surface of the cold plate is smooth and polished, which is suitable for covering in various ways. There are several methods of galvanizing oiled sheets, but the most common of these is the hot dip. In this method, the cold plate coil is opened and simultaneously enters the zinc metal bath. The unrolled coil emerges from the other side of the melting pool coated with a layer of molten zinc metal. The thickness of the zinc layer is adjusted using an air jet. In this way, the air pressure is delivered to the surface of the sheet material through the nozzle, both the freezing operation takes place, and the thickness becomes uniform.
weekly steel prices
As you know the price of slotted flat steel products changes rapidly and if you look at the weekly chart, you can see how the fluctuation of the prices is affecting the products in the market. When discussing a country's industry, especially manufacturers. One of the most important themes is often the long-term outlook for the industry, followed by the current costs associated with the raw materials required. Most industries foresee an increase in raw materials in their vision. They allocate the majority of their expenses to purchasing raw materials and replenishing stocks. Reasons for the increase in steel prices To be immune to inflationary pressures and to be more competitive in the target market. Therefore, for any economic activity, especially manufacturing activities, it is very important to understand the factors that affect the price of raw materials, which are also the magic weapon of the brand, which can attract more customers with a fixed profit and reduce production costs. Supply and demand are the primary causes of changes in steel prices. Globally, with the economic growth of developed countries and the increase in the demand for raw materials, the prices of metal raw materials have increased. Some of the important reasons are factors in export steel prices. Domestic steel prices are also constantly increasing. Considering the prices of major steel and the current costs of steel production facilities, excluding labor, are based on global prices. Another important factor in determining the price of steel is the domestic dollar price, which is the price of iron ore and other elements such as copper and nickel, which is obtained by multiplying the world price by the price.
historical steel prices
If you want to take a look at the prices of steel during the last decade or century, historical facts show that this price is affecting all the industries and economies of every country involved. The use of the steel industry in production is one of the factors that affect the country's industry and economy. This factor leads to the building, development and progress of nations and various societies. By taking a closer look at your daily life, you will notice the presence of the steel industry that you deal with every day. Most of the equipment and parts we use every day are made of stainless steel . The steel industry, from the earliest stages of mining to production and consumption, leads to job creation and the production of many jobs. Job creation such as steel mining, transportation, procurement of machinery and equipment, project consulting, use of manpower and training to update information, etc. can be considered as one of the factors in the existence of a country's steel industry. The steel industry is called the mother industry in all countries, which makes it the basis of all economic activity and thus the country's growth and development. Job creation and recruitment are only part of the interests of the country's steel industry. Producing steel sections from the initial stage requires labor, leading to occupation. The process of extracting steel from the mine, producing and casting crude steel, implementing secondary operations and rolling, and at the end of the consumption and sales stages, all these stages require experienced and knowledgeable labor to make the execution process run smoothly. In addition to all these performance factors, there is the educational component of the steel industry, which leads to the training of specialists and specialists who understand the technical knowledge of the present world.

coated steel bars
Steel bars are among those strategic products in the market that are used in the construction industry. The bars sometimes need to be coated so that the durability of the products gets higher in the concrete. Rebar is one of the most common end products of a hot rolling line and plays an important role in construction. The safety and strength of concrete structures are mostly related to the use of steel reinforcement in the area. Due to the low tensile strength of concrete, buildings have collapsed many times after devastating events such as earthquakes. In the 18th century, the use of steel bar in concrete structures became popular. Before this time, various materials such as concrete, stone, and brick made up the main structure of the structure. There are different types of rebar, each used for special situations. Rebar production is done using hot rolling. Rolling is one of the most common and best methods of manufacturing all kinds of sections. In this method, the molten ingot under pressure becomes a narrow cylinder. 
The compressive force is applied by a number of rollers mounted in the runway. In general, the following steps must be taken to produce rebar:
- Preheat raw materials
- Ingots
- cool down
- cutting
- Bundling
There are two main types of rebar, plain and ribbed. There are also different types of ribbed rebar, based on the shape of the ribs cut into the body. In general, the production standards for rebar are as follows:
- Single rebar or A1
- Spiral rib bars or A2
- Twill or A3 ribbed bars
- Composite ribbed bars or A4
The only difference between the different types of rebar is not limited to appearance. The chemical composition and mechanical properties of these products vary. In general, from A1 to A4 steel bars, the hardness increases with the increase in carbon content. 
steel price news today per kg
The news about the steel industry is changing every day because of its effects on countries and economies and the first thing affected by the laws is the price per kg. Today many companies are working hard to find a place in the market and finding it is very hard because of the plurality of the companies. Steel exports and presence in the world market are other advantages of the presence of the country's steel industry . A foothold in the global market requires the production of products of different quality, standards, and competitive prices. The prosperity of the country's economy and the source of foreign exchange is another benefit that the steel export brings to the country, which has a positive impact on the country's economy. It is worth mentioning that the country's economic and industrial development is not limited to the construction and steel sectors, but also progress and prosperity in machinery manufacturing, mining, shipbuilding, automobile manufacturing, transportation, pipes and profiles, packaging, and other industries. 
Other industries related to energy production and transmission also have a significant impact on the country's economic growth and development. The exchange rate is one of the most important factors in determining steel prices. Internationally, steel prices, along with supply and demand markets and other factors, have increased and experienced large fluctuations. fluctuation. On the other hand, the government uses a steel price policy to stabilize and protect its economic assets. In addition to steel, the prices of imported raw materials and refractory and alloy materials are also affected by currency fluctuations. Some say that having the steel industry as its parent industry can greatly influence a country's economic growth and progress. With this in mind, it is hoped that the government's policy team, with the help of experienced and knowledgeable experts, will put more investment in promoting economic prosperity through the steel market at the forefront of their work through concrete programs, and strive to increase consumption per inhabitant. 
steel pipe prices
Steel pipes are hollow long sections with a circular cross-section, mainly used to transport condensate and gas, and are also often used in construction. Price of steel pipes and steel slabs are very different and The existence of different steel pipe production methods has led to the diversity between these segments, each method has its advantages and disadvantages and includes a specific range of applications. The classification of steel pipes can be done according to different criteria, the two most common of which are based on the presence or absence of welds in the steel pipe or based on the material of the steel pipe. Welded or welded steel pipes Steel pipes that are made into thin cylindrical sheets and whose edges are welded at the ends are called folded steel pipes or welded steel pipes. Welding at this stage can be done in two ways, based on which different types of welded pipes are produced, as follows: Length seam steel pipe: These pipes have welds parallel to the length of the steel pipe. Spiral Steel Pipe: Spiral steel pipe has a spiral weld, which is actually a secondary process of joining shorter lengths of steel pipe together to form a long pipe. There is another type of steel pipe that has no seams due to its manufacturing process. These pipes are also known as Mannesmann steel pipes, indicating how they are produced. Succulent tubes are of this type. Seamless steel pipes are divided into the following categories according to their different production processes:
- Seamless steel tube mandrel mill or mill and mandrel
- Mannesmann steel pipe
- extruded steel pipe
- Centrifugal cast steel pipe
steel news
As mentioned in the previous part, the news of steel production and companies around the world are very different from one country to another. There are some difficulties in the market for selling the bars and steel TMT bars, however, unlike rebar, the Beam market is in an upward trend. The price of rebar has been lower than the price of Beams in recent months; however, some market participants believe that this valuation is unfair, arguing that although the price of rebar and section stainless steel sheet is based on the value of steel, even the cost of processing steel into shape is also much higher than the process of processing a bar for rebar, but the price should be higher than for rebar. However, there are only four main suppliers of rebar in the market, and demand for this product is sluggish, resulting in forced pricing that affects rebar transactions and prevents rebar prices from rising. 
Some experts even believe that the iron beam assessment in recent months has taken a toll on the factory. In global markets, however, the shadow of a recession still weighs heavily on the industrial metals market, and rebar trading is no exception. The price of rebar in China's domestic market has reached a price range of 3,900 yuan per ton, the lowest level since November last year. While demand in East Asia rose slightly last month due to the reopening and lifting of corona restrictions and China's decision to return the country's prosperity to pre-Covid-19 pandemic, fears of halted producers continue to give a boost to China's economy. A resurgence of positive COVID-19 cases in Shanghai, leading to new restrictions imposed in the region, and fears of a global recession due to interest rate hikes and restrictions by Western central banks as the Fed curbs inflation were the main factors behind successive reductions in rebar prices. In addition to the downward outlook for world markets, the war between Russia and Ukraine has of course also effectively reduced demand in East Asia.
