ABSTRACT:
A single-side embossed color steel sheet, and a method for manufacturing the same are disclosed. The steel sheet comprises a steel sheet substrate, a zinc or zinc alloy-plated layer, a non-chromate or chromate pretreated layer, a primary coat paint layer of modified epoxy or modified polyester, a color base paint layer, a printed layer, and a top coat clear paint layer. The printed layer exhibits a feeling of solidity with various feelings of texture and colors. The top coat clear paint layer serves to protect the printed layer from contaminants. The color steel sheet exhibits a remarkably enhanced feeling of solidity at an irregular surface thereof, and has enhanced contaminant resistance properties and environmental friendliness, thereby satisfying requirements for aesthetic design and functionality of products.
