Product details

ppgi coil refers to a pre coated metallurgical product made by continuously coating protective and decorative organic coatings or films on the surface of steel or aluminum strips. Internationally referred to as ppgi prepainted galvanized steel coil. It mainly consists of three parts: metal substrate, chemical conversion film, and organic coating. Organic coatings can be formulated into various colors and can be used to create various patterns and patterns through printing and embossing techniques, thus replacing traditional paint decorations. This type of steel plate combines the strengths of organic polymers and metals, and has good corrosion resistance and processing properties. The manifestation of corrosion resistance of color coated panels is usually represented by the degree of corrosion damage such as loss of gloss, discoloration, powdering, fine cracks, cracking, bubbling, and rust spots on the precoated metal with flower pattern. There are many factors that affect the corrosion resistance of color coated boards, including the type of substrate and its coating thickness, the type of coating and its layer and thickness, the environmental conditions for use, as well as various factors such as mechanical processing, transportation, storage, construction installation, and post construction maintenance in the application of

prepainted marble coated galvanized ppgi galvanized steel sheet. However, from the analysis of the coating characteristics and principles of color coated boards, the fundamental factors determining the corrosion resistance of color coil ppgl are the structural characteristics of the coating and the corrosion resistance of the substrate; The protection of coatings in atmospheric corrosive environment is mainly determined by the weather resistance or aging resistance of coatings.
