However, the ceramic siding material is heavy and poor in workability, and waterproof,
There was a disadvantage in that the coating film lacked in durability. Furthermore, when a surface-treated steel sheet is used as a metal-based siding material, especially as a surface material, there is a problem in corrosion resistance or chemical resistance against rust, etc. Therefore, it is necessary to coat with a special coating film with good corrosion resistance. There was a weakness that increased costs. In addition, the building panel had no fireproof property and the usable range was very narrow. Further, it is very difficult to fix the building panel, and as shown in FIG. 15, a loose hole is formed on the fixing surface and a gap a is formed between the fixing surface and the head β _{1 of the} fixing tool β.
(About 1 mm) to prevent the building panel itself from being firmly fixed.
