Description

  The present invention relates to an elongated plate-like panel used for, for example, a garden fence.

In general, in order to obtain corrosion resistance, this type of panel is formed by forming a panel body from an aluminum material into an elongated plate shape, and printing the whole surface of the panel body, for example, wood grain, in order to improve its appearance. A film is pasted, and the surface of the panel is finished to look like it was formed from wood. (See Patent Document 1)
However, in the above-mentioned metal panel, even if the surface pattern of the panel body is wood grain, the three-dimensional effect is poor and the commercial value is low.

  Therefore, the applicant of the present application attempted to form a three-dimensional effect on the pattern applied to the surface of the panel body by forming irregularities on the surface of the panel body at random.

However, when forming irregularities on the surface of the panel body at random, after forming the panel body, it is only possible to form irregularities at random on the surface by press molding or the like, which increases the manufacturing cost of the panel. The trouble that becomes.
