Explanation of the causes and countermeasures for paint peeling due to white rust and surface deterioration of galvanized steel.
One of the causes of paint peeling on galvanized materials is white rust. When white rust occurs, it becomes difficult for the paint film to adhere. Even immediately after galvanizing, reaction products are present on the surface. If zinc phosphate treatment or light polishing is not performed, the paint film is likely to lift. A storage environment with high humidity is also dangerous. Specific measures for galvanized materials are necessary. We also provide detailed examples of improvements in publicly available documents.

Company information
We are not just a "subcontracted painting factory." Established in 1958, our company has a foundation of painting technology and also specializes in chemical treatment, stripping, and cleaning, functioning as the "external surface treatment department" in your organizational chart. Based on our philosophy of "preparation is eight-tenths of the work," we emphasize participation from the "upstream process" before the drawings are finalized. We conduct test painting on a wide range of metals and difficult materials, and we produce the entire process from assembly, packaging, to delivery, thereby reducing your management workload. Additionally, by being able to perform zinc phosphate treatment in-house, we achieve stable painting quality. Furthermore, our micro-heating stripping technology, which does not use chemicals, maintains the electrical state of the "jigs (hangers)" that influence painting quality. Our approach of "pre-treatment determines painting quality" ensures the stability of the paint film during mass production. Rather than simply "applying specified standards," we work backwards to achieve optimal painting specifications and prevent scratches during transportation, sparing no effort in thorough discussions from the outset. This diligent preparation is the shortest path to preventing rework and minimizing total costs. From the development stage, please utilize the expertise of our specialists as part of your production line.
