Firstly, with high quality substrates, the requirements for surface, shape and dimension accuracy of substrates are becoming higher and higher. For outdoor use, such as small galvanized flat hot galvanized coil, flat galvanized coil without galvanized
flat and galvanized alloy hot galvanized coil, and for indoor use, such as galvanized steel coil, coated cold rolled sheet and aluminium coil.
Secondly, to improve the pretreatment process and pretreatment fluid, the number of equipment is small, low cost has become the mainstream process, and constantly improve the stability, corrosion resistance, environmental protection performance of the pretreatment fluid.
Thirdly, pay attention to the development of new coatings, improve the general polyester, polyvinylidene fluoride (PVDF) and plastic sol, obtain super color repeatability, anti-ultraviolet, anti-sulfur dioxide, improve corrosion resistance; develop anti-pollution, heat absorption and other functional coatings.
Fourth, the unit equipment is more perfect. For example, new welding machines, new roll coating machines, improved curing furnace, advanced automation instruments and so on.
Fifth, cold embossing technology has become the trend of development because of its low cost, beautiful appearance, three-dimensional sense and high strength.
Sixth, pay attention to product diversification, functionalization, high-grade, such as deep-drawing color coating plate, "grapefruit peel" color coating plate, anti-static color coating plate, pollution-resistant color coating plate, high heat absorption color coating plate, etc.
