　　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.

　　However, in the current situation of sluggish demand, sporadic production cuts in the market are only a drop in the bucket and have limited support for steel prices. The magnitude and feasibility of steel mills' production cuts in the later stage may become a key factor affecting steel prices. According to the third quarter report, steel companies have experienced widespread losses. According to relevant statistics, out of 34 companies, 21 have forecasted their third quarter performance, with 14 steel companies predicting losses and only 1 expecting year-on-year growth in performance. Recently, Hebei Province issued a notice on supporting the steel industry to resolve overcapacity, integrate, restructure, transform and upgrade its structure. Under the guidance of the department, Tangshan Industry actively and steadily resolves overcapacity in the steel industry, promotes industrial structure and transformation and upgrading. As of the end of March, the credit balance of institutions within the jurisdiction to the steel industry was 80.345 billion yuan, an increase of 367 million yuan from the beginning of the year. According to Brazilian estimates, the GDP of the state of Cear á has grown by about 6% in the construction of CSP steel plants, with Fortaleza's GDP growing by 12%. Once officially put into operation, the state's GDP is expected to grow by 12%, and Fortaleza's GDP is expected to grow by 24%.
