A screen for displaying an image projected from a beam projector. The screen base is formed with an incombustible metal sheet having silver-white color for displaying an image projected from a light source with nature color. A polished surface is formed on the screen base by polishing the screen base, so that the surface of the screen base has predetermined reflectivity. A surface hardening treatment is implemented on the surface of the screen base using a pickling treatment or an anodizing treatment. The surface reflection type screen formed with a non-combustible metal according to the present invention is excellent in surface hardness, corrosion resistance and acid-resistance so that the screen is easily repaired and maintained. In addition, the screen does not generate poisonous gas in case of fire, and also high quality of an image is displayed on the screen.
