　　Which is the cheapest hot-dip galvanized color steel plate

　　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.

　　Therefore, the impact of the bulk performance in the second quarter of this year is minimal. Huang Hongping, the on-site manager of Zhanjiang Freight Center, told reporters that Baosteel Zhanjiang Iron and Steel shipped the products to the mainland by railway. This batch of hot-rolled coil steel weighs 356.5 tons, with a single piece weighing 32.13 tons and a light weight of 16.2 tons. The center has reached a cooperation agreement with Baosteel Zhanjiang Iron and Steel, and it is expected that 2 million tons of steel products will be shipped annually by railway. Against the backdrop of deepening the supply side structural reform centered on reducing production capacity and inventory, we have turned our attention inward, delved into the potential for cost reduction, supply efficiency, and supply structure, and made every effort to adapt to the new normal of industry development, ensuring production and operation efficiency and maximization, "said General Manager Gan Guiping. The second is to strictly control the addition of new production capacity. Strictly supervise and implement the decision of 2013 to stop filing new capacity steel projects. In principle, the approval of new coal mines, technological upgrades and capacity increase projects should be stopped. The third is to improve support policies. Establish a special incentive fund for industrial enterprise structure, and provide incentives for personnel diversion and resettlement in local efforts to resolve overcapacity in accordance with regulations.
