　　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.

　　”Analysts say. According to the benchmark price of threaded steel, as of September 23, the benchmark price of threaded steel has fallen by 80 yuan/ton, a decrease of more than 3 percentage points. The market situation in the building materials market is not very optimistic. For the market situation in October, most businesses believe that we should take one step at a time, as the market is very contradictory. Enterprises are also relatively rational in inventory control. Statistical data shows that the steel inventory of enterprises is lower than the same period last year, and the year-on-year decline is basically 10% -20%, overall at a low level. In early June, the steel inventory of steel enterprises under the China Iron and Steel Association was 14.2 million tons, an increase of 1.7% month on month and a decrease of 12.93% year-on-year. According to Article 50 of the Anti Regulation, the investigation will propose countermeasures to the tariff authorities based on the investigation results, and the tariff authorities will make decisions based on the suggestions. Starting from June 29, 2016, the import of carbon steel fasteners originating from the European Union will continue to be subject to anti tax, and the implementation period will be extended. 5 years.
