Prepainted galvanized steel coil materials are divided into five categories: packaging, home appliances, building materials, optical materials and decorative materials. Among them, the color steel materials for household appliances are fine and fine, with high production requirements. The light retention rate is more than 90%. The above data shows that the aluminum-zinc color coated plate (AZ150, G345A, PVDF) is very suitable for buildings or other facilities in extreme environments, and has corrosion resistance and weather resistance.
In addition,pre painted steel coil have been widely used in foreign countries, which has good economics and is also a domestic development trend. It has a little bit of both steel plate and organic material. It has both the mechanical strength and easy formability of steel plates, and the good decorative and corrosion resistance of organic materials.
Many items now use new types of nature. In terms of metals, the breakthrough is alloys, and alloys are what everyone calls steel. Nowadays, more and more places are used, and the style and role of steel are also constantly strengthened. Color steel coils are even more popular. Steel is usually loaded in tons, and the requirements for the surface, shape and dimensional accuracy of the substrate are increasingly higher.
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-rolled coil emerging in time; indoor use such as galvanized steel coil, film cold-rolled sheet and aluminum sheet coil. Unit equipment is more complete. Such as the use of new welding machines, new roller coating machines, complete curing furnace, equipped with advanced automated instruments. Because cold embossing is cheaper than hot embossing, it has the characteristics of beautiful appearance, three-dimensional feeling, and high strength, which makes cold embossing production technology develop, and has the characteristics of beautiful, three-dimensional, and high strength, making cold embossing production technology a development trend.
