Types of metal sheets: their characteristics and application

Types of metal sheets

Metal sheets are one of the main types of industrial raw materials. They are used in construction and engineering, serve as a material for the production of roofing and facade coatings, parts of buildings and structures, even household appliances. Their purpose is determined by the characteristics and manufacturing method. Knowing the properties of each type of metal, it is easier to choose the most suitable for the implementation of their ideas and projects.

Types of Steel Sheets

The properties and scope of steel sheets largely depend on the method of their manufacture. The most popular and available for purchase large and small wholesale products of several categories.

  1. Hot-rolled sheets - made of low alloy or structural steel. The pre-cleaned and heated billet is rolled sequentially by shafts. In the process, the high temperature of the metal is constantly maintained. Due to the expansion and deformation of the substance and the formation of scale on the finished material, irregularities noticeable to the naked eye may appear, therefore, after rolling, the surface is calcined. A jagged edge is with a cropped or jagged edge. The main properties of such sheets are ductility, excellent weldability and corrosion resistance. In the hot way get the most thin metal.Hot rolled sheets
  2. Cold rolled are also obtained by passing a workpiece through a rolling mill. The finished sheet comes out smooth and smooth, without the defects inherent in the hot-rolled variety. However, it is less durable, ductile, corrosion resistance is also reduced.
  3. Galvanized steel sheets are thin products made of cold rolled steel with a protective anti-corrosion coating.
  4. Expanded - gratings, carved from sheets of the first two types. Such grilles are more durable and rigid than wicker ones. As a material for the manufacture of a variety of supporting structures, they are lighter than solid sheets.
  5. Corrugated - obtained by rolling a conventional steel sheet through corrugated shafts. Corrugation is always only on one side, it is rhombic and lentil. The drawing is standardized and due to the requirements of maximum resistance of the material to abrasion and reduce injuries at the application site.
  6. Sheet steel in rolls - a method of packaging large batches of metal of small thickness for bulk wholesale buyers. It is delivered in the usual or galvanized form.
Attention!

This is not a strict classification. Most types of rolled metal serve as raw materials for the manufacture of other types of metal products.

Application

The use of steel sheet metal of each type depends on their basic characteristics. The wrong choice of material for an important construction or critical assembly is fraught with destruction and human casualties.

  1. Hot rolled sheets are the most versatile. They are used in construction for the erection of metal structures as is and as a raw material for other types of metal building materials - channels, welded pipes, as well as riveted joints in places with a high load. Important components and parts for mechanisms are made from them - cars, trains, special equipment, water transport.
  2. Cold rolled sheets are used as the basis for galvanized products, metal tiles, corrugated board, tableware, including for conservation.
  3. The scope of galvanized steel sheets is extensive - construction, design, automotive. Housings of household appliances, machine tools, protective covers of equipment and tools are made of galvanized metal.
  4. From expanded metal sheets - ordinary, with a galvanized or polymer coating - fences, details of stairs, balconies, floorings are mounted. Rigid, sturdy gratings are used for screening bulk materials.
  5. Corrugated sheets are used in places with a constant load and the risk of injury - on stairs and passages, especially street ones, as flooring in warehouses and industrial premises, inside public transport, in mines and other mining facilities.
  6. Steel in rolls is a raw material for mechanical engineering, machine tool industry, the manufacture of corrugated board and metal, household appliances and equipment.
Steel coils

These are the most popular and universal types of sheet metal for construction, industry and design. Knowing the basic characteristics of each category, you can calculate the preliminary order value and buy sheets with optimal properties for the implementation of personal ideas and production projects or tasks.
