1. Insufficient plating time during processing
In order to save time and cost, some stainless steel processing plants will shorten the plating time. In theory, the longer the plating time, the higher the hardness of the coating. The longer the color duration on the stainless steel swatch, the longer the use time. The color will not fade after 5-10 years of use .
2. It is related to the application of stainless steel
We all know that stainless steel has some degree of acid-base imbalance. For example, some of the acid glue accidentally came into contact with the surface of the stainless steel color plate near coastal areas or during installation. If the treatment is not timely or the treatment method is improper, it will cause different degrees of damage to the surface color coating, and even cause the stainless steel color plate on the steel substrate to rust.
3. External Human Factors
Due to improper use, the surface of the stainless steel color plate will inevitably be damaged or faded. For example, scratches and corrosive liquids will fade stainless steel color plates, and long-term use or long-term sun and rain.
