Window of colour board door is to show with cold rolling plating zine plate is substrate, coating is able to bear or endure await model facing of Gao Kang corrode, the external use of chromatic coating building that makes by modern technology coils board (abbreviation “ colour board ” ) the raw material that regards production as door window. Our country has a few enterprise such as Bao Gang, Wu Gang and Guangdong, Beijing to be able to produce this kind of special material only.
