The color steel tile is made of color coated steel plate by rolling and cold bending. Color-coated steel sheets use galvanized, aluminum-plated, tin-plated steel sheets or cold-rolled steel sheets as substrates, and use color organic paints or films as decorative protective layers. The service life of color coated steel plates is largely restricted by the protective layer. There are many advantages for color coated steel plate to choose ASA film as a protective layer:

The weather resistance of ASA film is incomparable whether it is ABS or PVC film. ASA film is made of ultra-weather-resistant thermoplastic ASA resin and weather-resistant toner as raw materials, and is made by blending and extruding the film. The film has high strength and good toughness, and the color is lasting. It is especially suitable for outdoor harsh wind, sun, rain and corrosive environments. , Hongjingyin's ASA has been used in outdoor applications for 20 years and still has stable performance.

During the spraying process of primary coating (primer) and fine coating (front and back coating), color steel-coated steel plates have to face problems such as volatilization and leakage of coating solvents, and face increasingly stringent environmental protection issues. The investment in process costs will continue to increase. The ASA film coating only requires two processes: solid glue and film coating, which is simpler and more environmentally friendly. With ASA film as a protective layer, the decorative life can be increased to at least 20 years.
