Very low unit price and reasonable.
The plated surface is made of fine particles, making it very suitable as a base for painting and adhesion. When the material is immersed in anhydrous chromic acid solution, it becomes zinc-chromate plated. Immersing it in chromic acid solution dissolves the surface of the zinc plating, allowing the chromic solution to penetrate, resulting in a very fine surface that is likely to improve slip properties. Therefore, zinc plating may have poorer slip properties. If zinc plating is inadequate, another method is to immerse it in a 3% chromic acid solution. The 3% chromic acid treatment is used as a pretreatment for coatings that undergo very harsh processing such as pressing, bending, and cutting. (Automotive zinc-coated steel sheets undergo this chromic acid treatment.) The surface may not look much different from zinc plating to the naked eye, but similar to zinc-chromate plating, the rough zinc is dissolved by the chromic acid, resulting in a fine surface that is expected to improve slip properties. Additionally, the thin chromic acid film provides better corrosion resistance than zinc plating.

Company information
Our company was established in February 1954 with the aim of manufacturing non-ferrous metals and copper alloys. Subsequently, with the advancement of our business, we relocated and built a new factory at our current location in December 1966, where we began operations for the baking paint and electroplating of strip steel. On the technical side, we perform baking paint using various resin coatings through a dip method. In terms of plating processes, we consistently strive to supply excellent products, including zinc plating for rust prevention, zinc plating for paint undercoating, and colored chromate plating (chromic acid treatment), which has led us to our current status.
