All rolled metal products can be classified according to several parameters, such as manufacturing method, materials used, type of surface treatment.
Rolled metal products are metal products that are produced using rolling mills. They can be made by hot, warm or cold rolling (plastic deformation of a steel billet). Rolling is the main method of metal processing, after which products of different shapes and sizes appear.
How is rolled steel classified?
All rolled metal products can be classified according to several parameters, such as manufacturing method, materials used, type of surface treatment. If we talk about the manufacturing method, then the rolled metal can be:
- cold rolled - the rolling temperature is lower than the recrystallization temperature;
- hot rolled - the rolling temperature is higher than the recrystallization temperature.
It is quite natural that different materials are used in the manufacture of products. They can also be classified:
- ferrous metals - the alloy may contain iron with additions of carbon, nickel, chromium and copper; based on the percentage of additives, steel and cast iron are determined;
- non-ferrous metals are alloys of aluminum, nickel, copper, magnesium, lead, tin, zinc;
- stainless metals - iron alloys alloyed with chromium, nickel and manganese.
The processing method is also important, since a variety of tools are used:
- matt rolled metal;
- mirror metal rolling;
- polished metal-roll;
- calibrated metal rolling.
Thus, before buying, you need to clearly define the type of product and familiarize yourself with all its parameters. A conscientious seller will always provide the necessary documentation confirming the quality of the rolled metal.
Rolled metal products
Finished products, in addition to the profile size (large, medium and small), can also be divided into several main categories. For example:
- flat or sheet - this includes sheet steel, steel bands, strips, and the like;
- graded - rebar, circles, stripes, squares, hexagons, wire rods, and so on;
- shaped - channels, I-beams, profiles, corner profiles, rails and so on;
- pipe - welded steel pipes, seamless, shaped, etc.
Certification of rolled metal products
All rolled metal products sold by supplier enterprises are subject to certification. The issued certificate confirms that the product meets the standards and requirements
