PPGI coil, also known as pre-painted galvanized steel coil, is widely used due to its multiple adaptability and pretty appearance. Its wide applications also make it a promising investment project. Before purchasing it, let’s learn more information about this kind of hot-selling coil. How Is PPGI Coil Made? The pre-painted galvanized steel coil is named after the colored galvanized steel coil coated with organic coatings of various colors, referred to as PPGI coil. It uses galvanized sheets as the base metal. After surface pretreatment, one or more layers of organic coatings are applied to the surface, and then the product is baked and cured. That’s why PPGI steel actually has different layers, including base metal, zinc coating, chemical conversion coating, primer coating, and top/back coating. The popular colors are white, gray, sea blue and brick red, etc. PPGI coil has the advantages of both steel sheet and organic coating materials. It keeps the mechanical strength and easy forming function of the steel. At the same time, organic coatings provide aesthetic appeal and better corrosion resistance. What Are the Coating Structures of PPGI Coil? There are different painting methods used so that you can find the different structures of the PPGI coil. Below let’s have a brief review. 2/1: It means painting the upper surface twice, but the back area once, and baking twice. By comparison, the resistance to corrosion and scratch of the backside is poorer, but it has better adhesion. It is mainly used in PPGI sandwich panels. 2/1M: It refers to painting the upper and lower surfaces twice and baking once. The backside has good corrosion resistance, scratch resistance and processing formability, and also good adhesion. It can be used individually and in sandwich panels. 2/2: It means painting and baking the top and back sides twice. The backside has excellent corrosion resistance, scratch resistance, processing, and formability. It’s mostly used for single-layer panels, such as color corrugated roofing sheets. But the adhesion is poor, so it’s not suitable for sandwich panels. This is the most commonly used method. But for special uses, for example, panels for home appliances will be painted and baked three times. If you have special requirements, please inform us. Where Can PPGI Coil Be Used?
