　　The lightweight, beautiful, and excellent anti-corrosion properties of color coated rolls have sparked a trend of use in many industries, and they can also be directly processed. They are now widely used in industries such as construction, home appliances, furniture, and transportation.

　　Color coated roll coating structure: 2/1: Apply twice on the upper surface, once on the lower surface, and bake twice. The corrosion resistance and scratch resistance of single-layer back paint are poor, but it has good adhesion and is mainly used in sandwich panels; 2/1M: Apply twice on the upper and lower surfaces, and bake once. The corrosion resistance, scratch resistance, and processing formability of the back paint have good adhesion and are suitable for single-layer profiled panels and sandwich panels. 2/2: Apply twice on the upper and lower surfaces, and bake twice. The corrosion resistance, scratch resistance, and processing formability of double-layer back paint are mostly used for single-layer profiled panels, but its adhesion is poor and it is not suitable for sandwich panels.

　　Color coated coil substrate classification: Hot dip aluminum zinc substrate uses hot-dip aluminum zinc steel plate (55% Al Zn) as the new coating substrate, usually with an aluminum zinc content of 150g/㎡ (double-sided). The corrosion resistance of hot-dip aluminum zinc sheet is 2-5 times that of hot-dip galvanized sheet. Continuous or intermittent use at temperatures up to 490 ℃ will not result in severe oxidation or the formation of oxide scales. The ability to reflect heat and light is twice that of hot-dip galvanized steel plate, and a reflectivity greater than 0.75 is an energy-saving building material. The product of hot-dip galvanized steel plate coated with organic coating on hot-dip galvanized substrate is hot-dip galvanized color coated plate. Hot dip galvanized color coated sheet not only has the protective effect of zinc, but the organic coating on the surface also plays a role in insulation protection and rust prevention, with a longer service life than hot-dip galvanized sheet. The zinc content of hot-dip galvanized substrates is generally 180g/m2 (double-sided), and the zinc content of hot-dip galvanized substrates for external use in buildings is 275g/m2. Electroplated galvanized sheets are used as substrates, and the products obtained by coating with organic coatings and baking are electroplated galvanized color coated coils. Due to the thin zinc layer of electroplated galvanized sheets, the zinc content is usually 20/20g/m2, so this product is not suitable for outdoor use in making walls, roofs, etc. But due to its beautiful appearance and excellent processing performance, it can mainly be used for household appliances, audio systems, steel furniture, indoor decoration, etc.

　　Before the restructuring, in order to retain users at their respective levels of production, the result was inevitably an increase in operating costs and financial efficiency. However, during this period, users who are relatively strong have the ability to lower the selling price of products. In fact, if manufacturers produce too many products, resulting in oversupply in the market, it will inevitably lead to a decrease in product prices. Chen Ziqi: "In order for the steel industry to achieve fundamental improvement, it is necessary to resolve overcapacity. Of course, it should also be noted that resolving overcapacity is a long-term and arduous task, and it is impossible to complete it in one, two, or three years. Secondly, innovation ability is a necessary path that cannot be avoided. Without technological innovation, the steel industry will never have a way out. According to data from the China Iron and Steel Association, in the first half of 2016, member steel enterprises achieved sales revenue of 1.29 trillion yuan, a year-on-year decrease of 11.93%; profits of 12.587 billion yuan, a year-on-year increase of 4.27 times; losses of loss making enterprises decreased by 22.8% year-on-year; and sales profit margin was 0.97%.
