[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 The present invention provides the following technical solution:

[0023] A metal finishing strip includes an original building wall 1, a U-shaped support clip 7 on the back of the original building wall 1, a prefabricated fire-retardant plywood base layer 6 on the back of the U-shaped support clip 7, a metal hanger 5 on the back of the prefabricated fire-retardant plywood base layer 6, a first prefabricated decorative surface 3 on the back of the metal hanger 5, an adhesive layer 2 on the right side of the original building wall 1, a metal finishing strip 8 on the side of the adhesive layer 2, and an adhesive strip on the left side of the metal finishing strip 8. The metal finishing strip 8 is connected to the side of the prefabricated fire-retardant plywood base layer 6 by the adhesive strip and is installed by adhesive. This allows for a stable and effective finishing of the first prefabricated decorative surface 3 and the second prefabricated decorative surface 4, preventing adhesive overflow and wall contamination. The first prefabricated decorative surface 3 and the second prefabricated decorative surface 4 can form an external corner. The finished surface 4 forms a natural transition connection. A first finishing groove is provided on the left side of the metal finishing strip 8. The first finished surface 3 is inserted into the left side of the metal finishing strip 8.
