What is the development trend of color steel

First, the use of high-quality substrate has increasingly high requirements on the surface, shape and dimensional accuracy of the substrate. For outdoor use, such as small zinc flake flat hot-dip galvanized steel coil, non-zinc flake flat hot-dip galvanized steel coil, zinc alloy hot-dip galvanized steel coil is emerging in time; For indoor use, such as galvanized steel coil, coated cold-rolled sheet and aluminum coil. Color coated plate company

Second, improve the pretreatment process and pretreatment fluid. The number of equipment is small, and the cost is low. It becomes the mainstream process, and constantly improve the stability, corrosion resistance and environmental protection performance of the pretreatment fluid.

Third, pay 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; Develop pollution-resistant, heat-absorbing and other functional coatings.

Fourth, the unit equipment is more complete. For example, new welding machines, new roller coating machines, improved curing furnaces, and advanced automatic instruments are used.

Fifthly, because cold embossing is cheaper than hot embossing, and has the characteristics of beauty, stereoscopic feeling and high strength, cold embossing production technology has become a development trend.
