　　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.

　　Due to the gradual reduction in prices of cold and hot rolling, manufacturers are facing pressure from poor sales, difficult shipments, and rising inventory. In order to increase sales efforts, manufacturers are selling at low prices. Recently, major steel mills have lowered their prices for July, with some steel mills lowering the prices of ordinary carbon hot-rolled coils by 300 yuan/ton and cold-rolled base materials by 330 yuan/ton in July. From the perspective of production, in the first half of the year, crude steel production reached 400 million tons, a year-on-year decrease of 1.1%. Among them, crude steel production increased for four consecutive months in March, April, May, and June, with daily crude steel production reaching historic highs in April and June. The speed of crude steel production release also exceeded market expectations. Although crude steel production continues to decline, overall supply is still surplus, "Zhang Ji said. The steel industry has never been positioned as an export supporting industry. It took decades of effort for steel to achieve self-sufficiency, and it was not until 2005 that import and export balance was reached. Previously, it had always been more in than out, completely market-oriented. It should be noted that 70% of our export markets do not produce steel and must rely on imports.
