まれる。On the other hand, in recent years, with the diversification of uses for steel products, in particular steel towers, lighting poles, guardrails, various temporary frames,
For exterior panels, etc., there is a growing demand for colored hot-dip galvanized steel, which is more aesthetically pleasing and matches the surrounding environment than conventional hot-dip galvanized steel.
In addition to civil engineering, power communications, etc., a wide range of demand for colored hot-dip galvanized steel is expected in sectors such as transportation, agriculture, and fisheries.

するに至る欠点がある。The conventional coloring method for hot-dip galvanized steel is mainly to color the galvanized steel by painting.
Since Zn in the plating film of hot-dip galvanized steel is active,
The fatty acids that make up the oil component of the paint gradually decompose with alkali to form zinc soap. Therefore, there is a drawback that the paint film used for coloring does not adhere to the surface of the plating film and peels off.

煩雑な操作を行うことが余儀なくされている。Therefore, in order to prevent such defects, conventionally, steel is plated with molten zinc, and then the plated steel obtained is exposed to the atmosphere for 1 to 3 weeks to further coat the plated film with Zn (jH). ZnO1ZnCO3 and ZnC
It is necessary to perform the complicated operations of forming corrosion products such as No. 1, cleaning the surface of the plated steel, and then applying a coating for coloring.
