Prepainted Galvanized Steel Coils 15-25μm

Product Introductions

‌Color coated galvanized steel coil ‌ (PPGI, Pre-Painted Galvanized Steel) is a hot-dip galvanized steel coil based on the surface pretreatment and coated with color coating after baking curing products. It not only has the mechanical strength and easy formability of steel plates, but also has the good decoration and corrosion resistance of organic materials ‌.

Define and manufacture processes

Color coated Galvanized Steel coil is made of hot galvanized plate, hot plated aluminum zinc plate or electrogalvanized plate as the substrate, after surface pretreatment (such as chemical degreasing and chemical conversion treatment), coated with one or more layers of organic coating, and then baked and cured. This treatment makes the surface of the steel coil have various colors of coating layers, so the name of Color coated galvanized steel coil ‌.

Performance and application

Color coated galvanized steel coil has the characteristics of light weight, beautiful appearance, anti-corrosion and so on, and is widely used in advertising, construction, home appliance industry, electrical appliance industry, furniture industry and transportation industry. Its service life is about 1.5 times longer than that of ordinary galvanized steel coil, and according to the different use environment, different paint types can be selected, such as polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride and so on ‌.

Manufacturing process and materials

The manufacturing process of color-coated galvanized steel coil includes the steps of surface pretreatment, coating and curing. Pretreatment usually includes degreasing and phosphating treatments to ensure a good combination of the paint with the substrate

Applications

‌Color coated galvanized steel coil is widely used, mainly used in construction industry, home appliance industry, transportation industry and other fields ‌.

Building industry

In the construction industry, color coated galvanized steel coil is often used in the manufacture of corrugated board or sandwich board with polyurethane composite, these materials are widely used in steel structure factory, airport, warehouse, freezer and other industrial and commercial building roofs, walls and doors ‌. In addition, color-coated galvanized steel coil is also used to manufacture components in building structures, such as beams, columns, purlins, etc., as well as building roofing and wall materials to protect building materials from atmospheric and water corrosion ‌.

Home appliance industry

In the home appliance industry, color coated galvanized steel coil is mainly used in the manufacture of refrigerators, freezers, washing machines, air conditioners and other home appliance products shell and internal structural parts. The surface is hard and flat, with high wear resistance and corrosion resistance, which can effectively protect the surface of household appliances and extend the service life ‌.

Transportation industry

In the transportation industry, color-coated galvanized steel coils are used in the manufacture of oil pan, automotive interior parts and other components. Although its application is not as widespread as in the construction and home appliance industries, it is still important in the manufacture of specific components ‌.

Other fields

In addition, color coated galvanized steel coil is also used in advertising, electrical industry, furniture industry and transportation industry. Its light weight, beautiful appearance and good corrosion resistance make it widely used in these fields ‌.
