Introduction of prepainted steel plate

Time of issue: : 2021-09--22
Color-coated steel plate is made of cold-rolled steel strip and galvanized steel (electro-galvanized and hot-dip galvanized) as the substrate on the continuous unit. After surface pretreatment (degreasing and chemical treatment), it is coated with a layer by roller coating. Or multi-layer liquid coatings, which can be baked and cooled. Introduction Since the coating can have a variety of different colors, it is customary to call the coated steel plate a color coated steel plate. And because the coating is carried out before the steel plate is formed, it is called pre-coated steel plate in foreign countries. Color coated steel plate is an organic coating applied to the surface of steel. It has the advantages of beautiful appearance, bright color, high strength, good corrosion resistance, convenient processing and forming, etc., and it can also reduce costs and reduce pollution for users. Since the establishment of the first continuous coated steel plate line in the United States in 1935, color-coated steel sheets have been widely used. There are many varieties of color-coated steel sheets, about more than 600 kinds. Color-coated sheets have the advantages of both organic polymers and steel sheets. It has good coloring, formability, corrosion resistance, and decoration properties of organic polymers, and high strength and easy processing of steel plates. It can be easily processed by stamping, cutting, bending, and deep drawing. This makes products made of organic coated steel plates have excellent practicability, decoration, processability and durability.

Advantages of aluminum corrugated board

Time of issue: : 2021-09--22
1. Aluminum tile (corrugated aluminum plate, corrugated aluminum plate, profiled aluminum plate) is light in weight, and its density is only one third of that of steel. The same thickness is calculated to the price per square, the price of steel and aluminum is almost the same. 2. Corrugated aluminum plates (aluminum tiles, corrugated aluminum plates, profiled aluminum plates) are easy to process and shape, and the construction is convenient and quick, which greatly reduces the construction intensity. 3. Corrugated aluminum sheet (aluminum tile, corrugated aluminum sheet, profiled aluminum sheet) is beautiful, generous, and stylish. Aluminum skin is used for thermal insulation exterior decoration. The bright visual effect is very good. After the pipeline is wrapped, the overall vision is good. 4. Profiled plates (aluminum corrugated aluminum plates, corrugated aluminum plates) have a long service life, aluminum has good corrosion resistance, and its shelf life is more than 15 years. 5. Aluminum tile (corrugated aluminum plate, profiled aluminum plate) has high recycling value. The iron sheet will corrode after a few years of use, and there is almost no recycling value. However, aluminum coil (aluminum sheet) is recycled after recycling due to its corrosion resistance. The value is much higher, at least 80% can be recycled. 6. Aluminum tiles (corrugated aluminum plates, profiled aluminum plates) are widely used in thermal insulation projects in oil refineries, power plants, chemical plants, pharmaceutical plants, etc.
