metal surface is permanently shiny and not rusted

To ensure that the metal surface is permanently shiny and not rusted:

1. The decorative stainless steel surface must be cleaned and scrubbed frequently to remove attachments and eliminate external factors that cause modification.

2. 316 stainless steel should be used in seaside areas. 316 can resist seawater corrosion.

3.Some stainless steel pipes on the market cannot meet the national standards and cannot meet the requirements of 304 material. Therefore, it will also cause rust, which requires users to carefully choose products from reputable manufacturers.
