If the Ni content in this plating layer, which is an intermetallic compound consisting of a composition of Znl or/and old Znl, is less than 10 wt1, the η phase of Zn will appear, which will not only impair corrosion resistance but also cause defects in the upper layer. It is not possible to form a dynamic film uniformly, and if the Ni content exceeds 20wt1, the old 1
A β phase consisting of Znl appears, and the plating film becomes hard.
This is undesirable as it tends to cause powdering, and N
Even if i is in the range of 10 to 20 wt%, if the γ phase is not a single phase, a passive film cannot be uniformly formed on the surface.

After that, a passive film containing Zn and/or at least one of old oxides, hydroxides, and sulfides is formed thereon to a thickness of 0.01 to 0.51 L.

ば著しい差は見られない。The method for forming the passive film may be any method such as immersion treatment with an oxidizing solution (nitric acid etching, etc.), anodic treatment, hydrogen sulfide treatment, etc. If the thickness of the passive film is less than 0.011L, , it is not possible to completely uniformly cover the surface of the first layer, and if it exceeds 0.5μ, the passive film will easily peel off due to processing, etc., which is undesirable.0 The first layer of the present invention has red rust resistance. Moreover, the passive film has the effect of further improving red rust resistance and, at the same time, improving the design due to the color tone exhibited by the passive film. Passive film is old 0
(O)I), NizS, Zn oxide is black,
840H exhibits a color tone such as blue, and its design can be controlled by changing its composition. Furthermore, no significant difference is observed in the influence of the composition of the passive film on red rust resistance as long as the film is uniformly formed.

It is thought that the influence of the old 00H (Ni103, He0) is strong, but it is not clear.

る様になる。Wooden products are primarily intended for unpainted applications that require a particular design. Therefore, the occurrence of white rust is undesirable, and furthermore, the passive film as it is has some interference color, so it is unsatisfactory in terms of design depending on the application. The chromate film on the passive film is formed for the purpose of reducing this interference color and further imparting white rust resistance. The amount of the chromate film deposited is 10 to 300 mg/rn', particularly preferably 15 to 2001 g/m''. 10 mg
/m'', almost no white rust resistance is obtained, and 3001

しい。By the way, when using steel without painting, silk printing is often performed directly on the steel, but if the surface of the steel is coated with oxides, hydroxides, sulfides, etc., depending on the type of printing ink, Its adhesion deteriorates significantly. Therefore, the presence of a passive film or chromate film on the outermost surface is not favorable for silk printability.In order to improve this, organic resin is added as an upper layer of the passive film or chromate film.
Form to a thickness of 2 to 5 mm. As an organic resin film,
Acrylic resin, epoxy resin, and polyester resin are preferred.

発明を実施例によって具体的に説明する。If the resin film thickness is less than 0.2 g, not only will silk printability not be improved, but the resin film itself will exhibit interference colors, which is undesirable. If it exceeds 5 g, welding will be impossible and it will be disadvantageous in terms of cost. It is. Forming a resin film has the advantage of improving white rust resistance, completely eliminating interference color, and significantly reducing variations in appearance due to differences in the conditions for forming the passive film. The present invention will be specifically explained by examples.
