Advantages of Chalco Aluminum’s prepainted aluminum coil strip:

  1. Production equipment: Today's world-leading production line with continuous multi-coating and multi-baking starting from pre-treatment. The products produced by it are of stable quality and reliable. It is an advanced representative of domestic aluminum plate coating equipment.
  2. Process technology level: The earliest domestic enterprises that used roller-painted aluminum plates have accumulated rich experience in actual production for a long time, and have mastered the international advanced coating technology, which is feasible.
  3. Raw materials: from the beginning of the pretreatment to the production of the final product, the pretreatment agent adopts German Henkel and Chemitel: the coating adopts the resin produced by the American PPG company with a fluorocarbon content of more than 70%. Fluorocarbon coatings: Polyester coatings come from Becco, Sweden.
  4. Product quality: Due to the use of advanced equipment, high-quality raw and auxiliary materials and advanced production technology, the quality of the products produced is stable and reliable. It is a famous brand product in the color coated aluminum plate industry. Carbon, polyester coated aluminum sheet, peelable paint coated aluminum sheet, nano anti-dirty self-cleaning coated aluminum sheet, coated embossed aluminum sheet, etc. It is widely used in the industry of high-grade exterior wall aluminum-plastic panel products, ceiling panels, new roofs, walls and honeycomb panel products.
