We would like to introduce the "zinc plating" that we handle. It has a significant rust prevention effect on steel products. When zinc plating is applied to iron materials, even if there are pinholes in the plating film, the galvanic action between zinc and iron allows zinc to sacrifice itself to prevent rust on the iron material. Additionally, zinc is more cost-effective compared to copper, nickel, and tin, making it advantageous as a rust prevention plating for iron materials. 【Information】 ■ Platable materials: Iron-based materials ■ Advantages: Corrosion resistance ■ Plating tank size: 600×2,000×1,500mm *For more details, please refer to the PDF document or feel free to contact us.
