Structures such as street lights, signs, traffic lights, guard rails, road billboards, and road sign boards are used to hold the vehicle in a harsh environment and to maintain it for a long time. In order to prevent oxidation of the surface of the column, There are many cases of painting.

However, the main steel strut among the above-mentioned metallic materials has a problem that the coating painted by the poor environment such as ultraviolet ray after installation is easily peeled or discolored and the appearance is not very good even if it is aesthetically pleasing. There is a risk of corrosion. Therefore, the worker must perform the painting work again by using a crane or a ladder equipped with a basket at regular intervals, thereby wasting the cost of the painting work and increasing the work risk.

Among the metal materials, the stainless steel supports have advantages of corrosion resistance and smooth surface, but they are expensive and have a disadvantage that they have a cold feeling unique to metal as well as main steel. In addition, their support is dependent on the purpose of use .

However, with such a painting process, it is difficult to completely deviate from the hard atmosphere of the metal material, and various patterns are formed on the support to harmonize with the surrounding environment, and there is a limit to decorating the appearance more beautifully.

Accordingly, by forming patterns such as wood, marble, granite, and fancy pattern on the surface of a support such as a metal material, it is possible to avoid the artificial hard atmosphere of the metal material and to have a more natural feel and various appearance, There is a need to enrich the emotions of urban people living between.

In order to obtain the above product, a method of forming a pattern using a transfer paper on the surface of a metal material such as a street lamp post, a signal lamp post, a guard rail or a plate material is currently used. However, when the patterned layer is exposed to the outside, There was a problem. Recently, a method of forming a pattern on a structure by spraying a secondary paint with a plate material having a predetermined pattern passed through it has been proposed in Korean Patent Publication No. 10-2007-0009818. However, in order to form a pattern on the street lamp, it is necessary not only to form patterns on the outer circumferential surface of the street lamp pillar by using the plate material or the plurality of plate materials corresponding to the large street lamp column one by one, There is a problem in that the workability of the operator is greatly reduced due to the inconvenience that it is necessary to produce another plate having the pattern to be formed when forming a pattern of another shape on the outer circumferential surface of the lamp post.
