Indeed, this is a more difficult question to determine. Although we are in the process of producing stainless steel sheet, through various processes and processing to enhance the rust resistance.   Just like HOTIGOLD's decorative stainless steel sheet, in addition to using high-quality stainless steel raw materials, we also enhance its performance in all aspects during the manufacturing process, including of course rust resistance. However, due to many uncertain factors in the use environment, even pollution and corrosive substances can cause damage to stainless steel sheets.   Therefore, we will advise customers to avoid sharp objects from scratching the surface of the stainless steel sheet during daily maintenance, which will affect its anti-rust performance. In areas with harsh climates, we recommend using grade 304 or 316 stainless steel, while grade 201 stainless steel is not recommended because its performance is not as good as 304 or 316. Under normal circumstances, decorative stainless steel sheets are not prone to rust.
