Development trend of color coated steel coil industry

Color steel coil is widely used in buildings, household appliances, transportation and other places, such as color steel shed, construction site fence, because of its advantages of light weight, heat insulation, high strength, bending resistance and compression resistance, bright color, strong corrosion resistance, flexible and fast installation, etc. It has become one of the indispensable raw materials.




First: Quality requirements for color steel coil




In the future, the color steel industry will have higher and higher requirements on the surface, shape and dimensional accuracy of the base plate. For outdoor use, such as small zinc flake flat hot-dip galvanized steel coils and non zinc flake flat hot-dip galvanized steel coils, zinc alloy hot-dip galvanized coils will emerge in time; For indoor use, such as galvanized steel coils, film coated cold-rolled sheets and aluminum coils.




Second: Requirements for environmental protection such as material cost and reuse




In the future, the color steel coil process will become the mainstream process by improving the pre-treatment process and pre-treatment solution, with less equipment and low cost, and continuously improving the stability, corrosion resistance and environmental protection performance of the pre-treatment solution.




Third: Requirements for coating of color steel coil




In the future, color steel will pay more attention to the development of new coatings, and improve the general polyester, polyvinylidene fluoride (PVDF) and plastic sol to obtain super color reproducibility, UV resistance, sulfur dioxide resistance, and corrosion resistance; Development of pollution resistant, heat absorbing and other functional coatings.




Fourth: Innovation in machinery and equipment




In the future, the machine set for producing color steel coils will be more complete. For example, new welding machines, new roller coating machines, improved curing furnaces, and advanced automatic instruments are used.




Fifth: Improvement of molding process




The cold embossing technology has become a development trend because of its low cost, beautiful appearance, stereoscopic feeling and high strength.




Sixth: pursuit of product diversification




Focus on product diversification, functionality and high-end, such as deep drawing color coated plate, "grapefruit peel" color coated plate, anti-static color coated plate, pollution resistant color coated plate, high heat absorption color coated plate, etc.




At present, the supply of color steel coils has exceeded the demand. Therefore, how to improve the production process and other aspects has become a problem that suppliers need to consider. Only by complying with the development trend of the industry, can we better bring benefits to enterprises and promote the development of the industry and society.
