Cold Rolled Sheets: Applications, Standards, Benefits

For the production of metal products for the needs of the automotive industry, energy, construction by cold stamping, sheet metal is used. The cold-rolled material has a perfectly smooth surface, differs in hardness and thickness. The Orinnox website offers a wide range of products that meet domestic and foreign standards. We sell a wide range of stainless steel products.

In the manufacture of the sheet, carbon steel grades are used. The sheet thickness is 0.35–5 mm. Products are divided into types according to several criteria. One of the parameters is the quality of the surface finish. According to this criterion, four groups are distinguished. Accordingly, the first one has the highest finish, and the fourth one has the usual one. By accuracy, the sheets are divided into two categories — A and B. The edge is edged and unedged. Curved corners, folds, inversions are unacceptable.

In what areas is it applied

The products are characterized by high performance. This makes it suitable and in demand in various industries. Cold-rolled sheet metal is taken as a basis for the manufacture of metal structures. It produces high-precision products that are resistant to strong temperature rises. Corrugated board, galvanized, perforated sheets for roofing are also made from the material.

Cold-rolled sheet metal is purchased for construction needs. They do not do without it when they make a case for road transport, canning containers, decapir for enameled dishes. The popularity of the material is associated with the extreme simplicity of its processing. It is easy to press, weld, cover with a galvanized composition.

Additional processing methods make cold-rolled sheets universal. Orinnox also provides metal processing services of varying degrees of complexity. The desired products with clear, precise contours and lines are obtained by precision cutting. There is no fixed cost, the price depends on the volume and complexity of the order.

Production standards

There are several criteria that the manufacturer must follow. So, according to the standards, different degrees of sheet density are allowed. It can be normal, improved, high and extra high. Rolled products with a maximum thickness of up to 2 mm are divided into varieties depending on the ability to stretch. According to this criterion, four types are distinguished, from very complex to complex. Each customer sets their own performance requirements, so they may change.

To improve the technical and operational properties of the sheet, it is treated with additional compounds. They are also different. Special varnishes, galvanized, plastisol coatings are used. There is also a hot-dip galvanized finish. Blisters, weld breaks, bubbles and other defects on the surface are not allowed. If the material is reused, only one side should be perfectly smooth, without damage.

What are the main benefits

The demand for cold-rolled sheet metal is associated with the exceptional advantages that it has. The main pluses include:

  • high strength;
  • increased rigidity;
  • smooth surface, characterized by a pleasant sheen, minimal waviness;
  • dimensional accuracy.

Cold rolling technology produces very thin sheets of excellent quality with a perfectly smooth surface. Characteristics determine the scope of the product. The thinnest blanks are good for tin products and dishes. Decking for roofing and walls is made of material of medium thickness. Other types of steel are also obtained by cold rolling — electrical, stainless.

The Orinnox company offers to purchase sheet products from the best manufacturers. These are both domestic and foreign companies. In the manufacture, several technical conditions and GOSTs are taken as a basis. All presented materials exactly correspond to Russian and international standards. According to GOST, there are also different surface qualities of cold-rolled sheet metal.
