If there is a painting process after zinc plating, it will be handled together.
By applying zinc plating to the product, it can achieve high rust resistance and corrosion resistance. Furthermore, by applying chromate treatment to the zinc-plated surface, discoloration (whitening) of the zinc-plated surface can be suppressed and colored. This allows for a wide range of responses to the required corrosion resistance and aesthetic qualities when combined with painting.

basic information
Hot-dip galvanizing... applies a thick coating to enhance corrosion resistance and rust prevention. Electro-galvanizing... uses electricity to create a zinc coating layer, allowing for control over the thickness of the film. Zinc plating, when left untreated, forms an oxide film on the surface that turns white, so some form of post-treatment is applied. Most zinc-plated products undergo treatment with hexavalent or trivalent chromate. These treatments include colored (yellow) chromate, unichrome (glossy chromate), trivalent chromate clear, and black chromate. Additionally, by painting over the zinc plating, it is possible to add color, gloss, thickness, design, and special functions. A zinc phosphate parkerizing treatment can also be applied as a base for painting. This can be expected to provide high adhesion between the paint and plating, as well as high corrosion resistance. We can accommodate various patterns. We are available for consultations, so please feel free to contact us.

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.
