Sheet metal material, also known as sheet metal, is a type of metal material widely used in various industries. Common sheet metal materials are
1 Cold rolled sheet steel
Cold-rolled steel sheet is the abbreviation of carbon structural steel cold-rolled sheet, which is made of carbon structural steel hot-rolled steel strip after further cold rolling to make thin steel sheet. Because it is rolled at room temperature, no oxide sheet is produced, therefore, the surface quality of the cold plate is good, the dimensional accuracy is high, coupled with annealing treatment, its mechanical properties and technological properties are better than the hot-rolled thin steel sheet, is one of the most commonly used sheet metal materials, with low cost, easy processing, moderate strength, good bending performance and other characteristics.
2 Electrogalvanized cold rolled sheet steel
Electrogalvanized cold rolled thin steel plate, also known as "electrolytic plate", refers to the process of continuous deposition of zinc from the aqueous solution of zinc salt to the pre-prepared steel strip performance on the electrogalvanizing line under the action of electric field, and the surface galvanized layer is obtained because of the limitation of the process.
3 Hot dip galvanized sheet steel
Continuous hot dip galvanized sheet steel referred to as galvanized sheet or sheet iron, is a thickness of 0.25~2.5mm cold rolled continuous hot dip galvanized sheet steel and steel strip, compared with the surface of galvanized sheet, its coating is thicker, mainly used for sheet metal requiring strong corrosion resistance, there are two types of flat and corrugated (waveform). It is often used in the manufacture of roofing, coiled pipes and various containers. Ungalvanized sheet metal is commonly known as black iron sheet
There are normal zinc flowers, small zinc flowers, light zinc flowers several.
4 aluminum-zinc coated plate
The aluminum-zinc coated plate refers to a protective and decorative coating on the surface of the aluminum-zinc alloy plate through the coating process. Aluminum zinc alloy plate is a composite plate made of galvanized plate after hot dip aluminum plating/aluminum zinc alloy coating. Its surface has dual protection of aluminum and zinc, which can resist corrosion, oxidation and wear well. The coating is usually made of polyester, silicone modified polyester, polyvinyl fluoride and other materials, which has excellent weather resistance, heat resistance, corrosion resistance and decorative.
The above 2, 3 and 4 steel plates are collectively referred to as coated steel plates, which are widely used in domestic communication equipment. After processing, coated steel plates can no longer be electroplated, painted, and the cuts can be used directly without special treatment, and special phosphating can also be carried out to improve the corrosion resistance of the cuts. From the perspective of cost analysis, the use of continuous electrogalvanized thin steel plate, the processing plant does not have to send parts to electroplating, saving plating time and transportation costs, in addition, the parts do not need to pickling before spraying, improving the processing efficiency.
5 Stainless steel plate
Stainless steel plate is usually a combination of stainless steel plate and acid-resistant steel plate. During the development process, several categories of stainless steel plates of various properties have gradually formed. Divided into austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, austenitic ferritic biphase stainless steel plate 4 kinds. Because it has the advantages of strong corrosion resistance, good electrical conductivity and high strength, it is widely used, and the material price is very expensive, which is 4 times that of ordinary galvanized sheet.
6, anti-embroidery aluminum
Anti-rust aluminum plate is a new type of metal material. It is a commonly used product of aluminum-manganese alloy series. Due to the manganese alloy element, this product has excellent anti-rust characteristics, and is also known as anti-rust aluminum plate.
The price is lower than other series of aluminum plates, and it is the best for rust prevention.
7 Aluminum alloy plate
Aluminum alloy plate is composed of aluminum and auxiliary alloy, usually aluminum copper, aluminum manganese, aluminum silicon, aluminum magnesium, etc., low density, but high strength, close to or higher than high-quality steel, good plasticity, can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, second only to steel.
