But in some special circumstances, the surface of the colored stainless steel will have a different degree of fading, the following Wuxi Zhongxing Yide tell you in what case will fade.1, processing time is not enough color plating time in order to save time and cost, some stainless steel processing plant will shorten the plating time. Theoretically, the longer the plating time, the higher the hardness of the plating layer. The more durable the color on the colored stainless steel, the longer the use of time, the use of 5-10 years after the color will not fade. 2, with the application of stainless steel has a relationship we all know that stainless steel has a certain degree of acid-base imbalance. For example, in the coastal areas near or during the installation process, some acidic adhesive accidentally touched the surface of colored stainless steel, no timely treatment or improper treatment method, will cause different degrees of damage to the surface color coating, and even lead to the steel substrate on the colored stainless steel rust.3, external human factors colored stainless steel surface due to improper use, it is inevitable that the damage or fading. For example, scratches and corrosive liquids will make colored stainless steel fade, as well as long-term use or long-term sun and rain.
