Metal rolling is what? Rolled metal (pipes)

Rolled metal is in demand in various areas of production and construction. Its sale ensures the timely execution of repair plans. When designing a building, metal floors are planned to increase its reliability. All this indicates the need for close acquaintance with this type of product.

Rolled metal is a special workpiece machined on the machine, which can have a different shape depending on the future industry.

Types of rolled metal

- Color. From brass, copper, tin and other metals. This type of rolled metal is used in instrument making and machine building. Lightweight and flexible parts are used for aircraft assembly.

- The black. From steel and cast iron. It is used in industries that require reliability and durability from products.

Metal rolling is a finished product of standard shape and dimensions. 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 has rolled metal, pipes are the most common. This kind of products can have a single-layered and multi-layered structure. Technologies allow producing pipes not only of circular but also rectangular, square and oval sections. A round pipe is considered the most popular, since it has excellent throughput, relatively small amounts of raw materials are needed for manufacturing, and the pressure on its walls is distributed evenly, which prolongs its service life. By the type of weld, the products can be spiral or longitudinal.

Pipes are used for transportation of various liquids and gases. Depending on the product being transported, the metal-roll alloy will be different. This is because when interacting with gases and reactive substances, corrosion and deformation can appear on the pipes. They can also be used not for their intended purpose, for example, as a support or a fence.

Basic parameters and types of pipes

The thickness, diameter and length of the products are very important. In every large company there are gaugers. They help in case of customer's difficulties to calculate the exact length of pipes and their diameter. Sellers also indicate the weight of rolled metal.

Metal rolling - it's not just products released in a certain way. All pipes require additional treatment against the effects of adverse factors such as corrosion, oxidation and rust. For this, the metal is covered with protective layers of special compounds or galvanized. Such measures help to extend the service life. Protect products from temperature changes are capable of various plastic housings and layers of heaters.

A special pipe is a product with a non-circular cross-section, for example, an oval one. According to manufacturers, the most popular among customers uses products with a rectangular and square section. The material for such pipes is most often carbon and low-alloy steels.

Products of various shapes are produced by the method of cold or hot deformation. That is, the workpiece is first bent to the design section and welded. Then the round tube goes to the molding, where it is given the necessary shape.

The price of rolled metal depends on the parameters of the product: the thickness of the walls, length and diameter.

Sheet

Rolled metal is also a steel sheet. It can be produced on machines by cold or hot rolling. During this process, the steel workpiece is converted into profiles.

Types of sheet metal

Hot-rolled sheets serve 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-rolling sheets are widely used in the automotive and military industries. Such products serve as raw materials also for machine tools. It should be understood that metal rolling is not only raw materials for complex production. Every day on the roofs of houses you can see the corrugated board, which is also a kind of cold - rolled galvanized sheets.

Of all the types to which the rolled metal is divided, the sheet and the pipe are considered the most common. In addition to them, there are shaped and profiled metal products. The latter include fittings. They can be used both for reinforcing concrete structures and for building structures in which they do not hide in the thickness of walls.

Thus, rolled metal is not only the usual round pipes and profiles. This class of products also includes fittings, channel bars, wires, hexahedrons and beams.

When buying, you need to pay attention not only to the price and total weight of rolled metal, but also to each letter in its marking. Since each type of work uses its own kind of products.
