Metal sheet: what is it, how is it made and how much does it cost?
Sheet metal is often used in the manufacture of products. What is it and what role does it play? Where is it used and how is it made? What does sheet metal matter for the industry? All these questions will be answered within the article.
What is called sheet metal?
Initially, we define the terminology. Sheet metal is a blank for manufacturing products from the corresponding material. The main parameters are thickness and area. Let's start with the first. Almost everywhere used material has a thickness of 3, 5, 10 or 20 millimeters. Modern industrial complexes of metallurgy can produce blanks, the area of which reaches hundreds of square meters. But sheet metal of this size is almost never used, both because of the complexity of transportation, and because of the problem of installation. Therefore, the material is cut into smaller pieces directly in production.
How is sheet metal made?
There are two manufacturing techniques: hot rolled and cold rolled. The first is implemented in such a way that the source is hot steel, which passes through a rolling mill. The thickness of the sheet can vary in the range from 1 to 200 millimeters. Machines for sheet metal or manufactured at the factory, or at special machine-building enterprises that specialize in equipment for metallurgy. The use of the products obtained is possible in various fields. The difference of cold-rolled metal is that they pass the cold billet through the rolling mill of the enterprise. Due to the greater difficulty of manufacturing this type of sheets, their thickness is less than hot rolled: not more than 5 millimeters. They are used exclusively for stamping parts. On the production can be carried out additional manipulations. So, to obtain blanks of the desired configuration can be applied flexible sheet metal. It implies a change in the original form in a convenient to facilitate subsequent work. Bending sheet metal offers such opportunities that you can even see a prototype of the future part in the workpiece.
How much is sheet metal?
How much is such a product? To begin with, we will determine the extent to which it is released. The cost of the party directly depends on this factor. Since metallurgical enterprises are interested in selling as much of their products as possible. In most cases, the cost depends on the tonnage: up to 500 kilograms, up to 1 ton, up to 3, up to 5, over 5. Buying the smallest batch of sheet metal will cost the most. In such cases, the cost hovers around 75 thousand rubles per ton. The larger the batch, the cheaper the sheet metal is. The price is not much different, but still for bulk buyers discounts are substantial amounts. When buying 4 tons you have to pay about 72 thousand rubles. All prices for intermediate batches of goods are the average between this minimum and maximum. But it is necessary to take into account when studying this issue that any enterprise is interested in maximum utilization of its production capacity. Therefore, with significant orders, the tonnage of which exceeds 5,000 kilograms, there are usually separate negotiations on manufacturing, during which the price is negotiated separately between the representatives of the interested structures.
Where is sheet metal used?
Opportunities, where and what to apply, the world is full.But first you should report information that was not mentioned earlier. Rolled metal is divided into two categories: color and black. So, the first type, due to its diversity, enjoys considerable popularity in various areas of production of consumer goods: in electronics and a number of other cases. From it are created and luxury items. While ferrous metallurgy works on such important areas of economic activity as the automotive industry, railway transport, chemical and food industries. Here the possibilities of application are directly dependent on the thickness of the sheets. In addition, ferrous metallurgy has found its application in the military sphere, in construction (the supply of reinforcement for reinforced concrete structures is particularly important). The fact that the material is galvanized, corrugated and other types also has a significant impact on the application.
