Building signage can be divided into rooftop illuminated lettering and curtain wall illuminated lettering, with the selection of materials generally being stainless steel and aluminum. Luminous lettering using 316 # stainless steel or aluminum plate as the substrate is usually used in coastal areas, while luminous lettering using 304 # stainless steel as the substrate is usually used in inland areas. By setting up building signage, it can bring more opportunities to the enterprise and hotel.
