About US
HAOMEI----specializes in producing color coated aluminum for Exterior and Interior applications,. color coated aluminum are widely used in ACP,curtain panel,honey comb panel,shutter,roofing and most of the decoration areas. We have introduced in most advanced computerized metal processing equipment ,Pre-treatment by the German pharmaceutical Henkel and Kenema Mittel. PPG paint coatings using the United States, Sweden BECKER paint, the United States Lili valspar paint. PVDF, perfluorocarbons can be divided into surface coatings, self-cleaning nano-Kang Wu fluorocarbon coating, coated polyester, acrylic coating.With the superior quality and advanced management,our products had been export to Euro, Middle East, North America ,East Asia and many other areas and countriers.
