Block Neodymium Magnet with Different Coatings
Prepainted Stainless Steel coil Why choose prepainted stainless steel?
1. Reduce light pollution: The coating can solve the impact of large-area stainless steel light panels on surrounding buildings.
2. Resolve galvanic corrosion: the surface of stainless steel has dust or foreign metal particles attached to it. Galvanized steel purlin and stainless steel ,in moist air, the condensed water between the two will be connected. As a microbattery (potential difference), it will trigger an electrochemical reaction and accelerate the corrosion and perforation of the contact points. After the stainless steel is coated with an organic coating, it forms insulation and prevents galvanic corrosion.
3. Prevent chemical corrosion: In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), it will form sulfuric acid, nitric acid, and acetic acid liquid spots in the case of condensed water, which can cause chemical corrosion, especially in coastal areas and In islands, the corrosion performance of chlorinated steel solution on stainless steel is weak, and the annual corrosion rate of austenite in salt water is at least 0.05-0.5mm, and there is a tendency for pitting corrosion and stress corrosion cracking. After the stainless steel is coated, it can isolate the contact of the corrosive medium with the surface of the steel plate.
4. Reflect the individuality of the building: the color or texture of the roof and wall can be customized according to the user's requirements.
