Color steel coil, namely color coated steel plate, is a product made by coating organic coating on the surface of strip steel after continuous chemical transfer coating treatment such as degreasing and phosphating on the production line. It is also a
kind of composite material, which has both the characteristics of traditional steel and organic materials. It has not only the mechanical strength and easy forming performance of traditional steel, but also the excellent decoration and corrosion resistance
of organic materials.
Although the performance advantage of color steel coil is obvious, its use is wide, and the demand for color steel coil in all walks of life is still increasing, but the wholesale volume of domestic color steel coil is still not ideal, the growth rate
is not obvious compared with that of foreign color steel coil in recent years, the competitive pressure is too large, the price advantage is not obvious, and the main problem is that domestic color steel coil still has the following problems.
Although the production capacity of hot-dip galvanized steel sheet for building materials with the largest consumption is very large at present, there is a lack of such excellent substrates as zinc alloy coated steel coil and zinc free flat hot-dip galvanized
2. The variety and quality of domestic coatings can't meet the demand completely, and most of them rely on imports. The high cost is that most of the color steel plate manufacturers can't reduce the price, and their competitiveness is
greatly reduced. The plastic film needed for the color plate with film still depends on imports, lacking the high-grade color plate with thick coating, functionality, high strength and rich colors;
3. The lack of standardization of products results
in serious waste of resources. There are too many low-capacity units with a production capacity of less than 40000 tons / year, and there are problems in product quality and environmental resource protection. 4. There are too many new color coating units
in China, far exceeding the market demand, resulting in low operating rate of many color coating units, and even shutdown.
Industrial technology is constantly developing. Only by following the pace of advanced technology, constantly improving themselves
and improving the production process, can domestic color steel manufacturers stabilize the low temperature in this field and increase the wholesale demand for domestic color steel coils in various industries.
