　　Color coated roll supplier

　　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.

　　Steel structures are widely used in high-rise buildings, residential buildings, bridges, industrial plants, and spatial structures (such as waiting halls, sports halls, exhibition halls, warehouses, etc.). Due to the advantages of light weight (1/5 of brick and concrete structures), high strength, high compression resistance, good seismic resistance, fast construction, short construction period, large service area (3%~5% more than reinforced concrete structures), long service life (80~100 years), and minimal impact during construction, steel structures are widely used,. September is the off-season for steel demand in the market. With the decline in steel prices and the increase in "double reverse" cases and trade disputes against China's steel products, the difficulty of steel exports will increase in the later period. However, due to the large price difference between domestic and international markets, China's steel exports have strong competitiveness and will not be significantly exported. It is expected that steel exports will continue to maintain a certain degree of year-on-year growth in the third quarter. The second one is within our own organization. After two years of losses, we are also taking some measures internally. We are also doing some structural work, such as using steel for wind power. Wind power has developed rapidly in the past two years, and we are seeking breakthroughs in using steel for wind power. ”Freezing is not a one-day cold, and the steel industry must be impatient to reduce production capacity. For enterprises themselves, diligently improving internal strength, upgrading quality, market positioning, and developing differentiated products may be the development path in the current "cold winter".
