Metal rolling is in demand in various areas of production and construction. Its sale ensures timely implementation of repair plans. When designing a building, to increase its reliability, metal floors are planned. All this suggests the need for close acquaintance with this type of product.
Metal rolling is a workpiece specially processed on the machine, which can have a different shape depending on the future industry of application.
Types of metal
- Color. From brass, copper, tin and other metals. This type of metal is used in instrumentation and engineering. Lightweight and flexible parts are used in the assembly of aircraft.
- The black. From steel and cast iron. It is used in industries requiring reliability and durability from products.
Metal rolling is a finished product of standard shape and size. Among them: pipes, fittings, beams, channels, sheets, strips and others. Some of the types of products need to be considered separately.
Pipes
Of all the types that rolled metal has, pipes are the most common. This type of product can have a single-layer and multi-layer structure. Technologies allow to produce pipes not only annular, but also rectangular, square and oval. A round pipe is considered the most popular, since it has excellent throughput, it requires a relatively small amount of raw materials to manufacture, and the pressure on its walls is evenly distributed, which extends its service life. By the type of weld, products can be spiral- seam or straight- seam .
Pipes are used to transport various liquids and gases. Depending on the product being transported, the metal alloy will be different. This is because when interacting with gases and chemically active substances, corrosion and deformation can appear on the pipes. They can also be used for other purposes, for example, as a support or fence.
Key parameters and types of pipes
The thickness, diameter and length of the products are very important. Every large company has a measurer. They help in case of customer difficulties to calculate the exact pipe length and diameter. Sellers also indicate the weight of metal.
Rolled metal products are not just products manufactured in a certain way. All pipes require additional processing from exposure to adverse factors such as corrosion, oxidation and rust. For this, the metal is coated with protective layers of special compositions or galvanized. Such measures help extend the life of the product. Various plastic cases and insulation layers are able to protect products from temperature extremes.
A profile pipe is a product with a different cross-section, for example, oval. According to manufacturers, the most popular among customers are products with rectangular and square sections. The materials for such pipes are most often carbon and low alloy steels.
Products of various shapes are produced by cold or hot deformation. That is, the workpiece is first bent to the calculated cross section and welded. Then the round pipe goes to the molding, where it is given the necessary shape.
The price of metal rolling depends on the product parameters: wall thickness, length and diameter.
Sheet
Metal rolling is also a steel sheet. It can be produced on machines by cold or hot rolling. During this process, the steel billet is converted to profiles.
Types of sheet metal
Hot rolling sheets are used for the construction of metal structures in construction. After bending such blanks, corners and channels are obtained, which are already used in engineering and shipbuilding.
Cold rolled sheets are widely used in the automotive and military industries. Such products also serve as raw materials for machine tools. It should be understood that metal rolling is not only raw materials for complex productions. Every day on the roofs of houses you can see corrugated board, which is also a type of cold - rolled galvanized sheets.
Of all the types into which metal rolling is divided, sheet and pipe are considered the most common. In addition to them, there are shaped and high-quality rolled metal products. The latter include reinforcement. They can be used both for reinforcing concrete structures, and in the construction of structures in which they do not hide in the thickness of the walls.
Thus, metal rolling is not only the usual round pipes and profiles. This class of products also includes fittings, channels, wires, hexagons and beams.
When buying, you need to pay attention not only to the price and total weight of metal, but also to each letter in its marking. Since each type of work uses its own type of product.
