Color coating production line is an innovative process that integrates advanced coating technology and automated production process. It takes the pre-treated steel as the substrate, and through continuous operation, evenly coats the steel surface with various organic coatings, and then bakes and cures to form a richly colored coating with excellent performance. This process not only gives the steel a wide range of colors to meet the individual aesthetic needs of customers in different regions for building decoration and home appliance manufacturing, but also significantly enhances the steel's corrosion, abrasion, and weathering resistance so that it can easily cope with the complex and changing climatic conditions of different places, from the sandy deserts to the high temperatures and high humidity of the tropics.
