Development trend of galvanized color coated steel coil

First, because the cost of cold embossing is lower than that of hot embossing, and it has the characteristics of beauty, three-dimensional feeling and high strength, the production technology of cold embossing has become a development trend.

Second, the unit equipment is more complete. For example, new welding machines, new roller coating machines, perfect curing furnaces, and advanced automatic appearance of equipment are selected.

Third, high-quality substrates are selected, and the requirements for the appearance, shape and scale accuracy of the substrates are increasingly high. For outdoor use, such as small zinc flower flat hot-dip galvanized steel coil, non zinc flower flat hot-dip galvanized steel coil and zinc alloy hot-dip galvanized coil that is timely rolled up; For indoor use, such as galvanized steel coil, coated cold rolled plate and aluminum plate coil.

Fourth, improve the pretreatment technology and pretreatment liquid. The number of equipment is small and the cost is low. It will become a mainstream technology to continuously improve the stability, corrosion resistance and environmental protection function of the pretreatment liquid.

Fifth, pay attention to the diversification, function and advanced of commodities, such as deep drawing color coating plate, "honey pomelo skin" color coating plate, anti-static color coating plate, pollution-resistant color coating plate and high heat absorption color coating plate.


Sixthly, the development of de novo coating is to improve the general polyester, polyvinylidene fluoride (PVDF) and plastisol to achieve super color reproducibility, UV resistance, sulfur dioxide resistance and improved corrosion resistance; Develop functional coatings such as pollution resistance and heat absorption.
