In the case of double stone panels, marble and other stones are collected, cut into plates in the factory, and then cut to a suitable size.

Then, it is transported to the construction site, and is attached to the wall of the building using angles and adhesives.

However, since the impact strength of stone is weak, there is a large loss due to breakage in the course of cutting, transportation, and installation.

In order to prevent such breakage, it is necessary to cut to a thickness of about 30 mm. At this time, inconvenience of handling and adhering construction due to increase in self weight and cost of rough stone (marble) are increased.

As a result, the stone panel can not be manufactured in a large size, and there is a problem that there is no continuity of the natural stone pattern when it is manufactured in a small size or there is a loss.

The metal panel is made of aluminum, stainless steel or the like and is used not only for a building finishing material but also for street lamps and traffic lights.

Such a metal panel does not inconvenience in construction due to loss and weight due to breakage as compared with a stone panel.

However, as described above, since the conventional metal panel can not have various appearance, only the metallic texture appears on the surface of the metal panel.

On the other hand, in order to finish the exterior walls of various buildings, instead of stone panel or metal panel, there is a case where the effect of stone panel is applied by applying stone exterior finishing material to a cement face which is a scene in the field, And there is a problem that it is not environmentally friendly because a bad smell is generated.
