what type of aluminum are road signs

Road sign materials are generally made of high-quality aluminum alloy plates, such as 3003 and 5052 alloys, with engineering-grade or high-strength reflective film attached to the surface, which has a good reflective effect at night. Then cut the aluminum plate and reflective film (square, round) according to the national standard size. Then wash the surface of the aluminum plate, polish the aluminum plate with a white clean cloth to make the surface of the aluminum plate rough, wash it with water and dry it; then use a hydraulic press to paste the reflective film on the cleaned aluminum plate of road traffic signs for later use. Computer typesetting patterns and characters, and using a computer engraving machine to directly print out the pictures and characters on the reflective film, and finally the engraved patterns and silk-screened patterns are pressed on the aluminum plate of the base film with a squeegee.
