Product Description

Heat Resistance Prepainted Steel Coil Has Excellent Welding Performance​

Color-coated rolls are light, beautiful, and have good anti-corrosion properties, and can be processed directly. The colors are generally gray, sea blue, and brick red. They are mainly used in advertising, construction, household appliances, electrical appliances, furniture, and transportation. Industry. The coating used for color-coated coils should select appropriate resins according to different use environments, such as polyester silicon-modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride, etc. Users can choose according to the purpose.

Color-coated coil is a coil made of galvanized sheet as the substrate. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are coated on the surface, and then baked and cured. The product. You can choose a variety of color paints for processing according to your preferences, and then they are commonly known as color-coated rolls.

Color coated roll substrate classification

Hot-dip galvanized substrate

The product obtained by applying an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color-coated sheet. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also has the function of insulating protection and preventing rust, and the service life is longer than that of the hot-dip galvanized sheet. The zinc content of the hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the highest galvanized amount of the hot-dip galvanized substrate for building exterior is 275g/m2.

Hot-dip galvanized substrate
Hot-dip galvanized steel sheet (55% Al-Zn) is used as the newly coated substrate, usually containing 150g/㎡ of aluminum and zinc (both sides). The corrosion resistance of hot-dip galvanized sheet is 2-5 times that of hot-dip galvanized sheet. Continuous or intermittent use at temperatures up to 490°C will not severely oxidize or produce scale. The ability to reflect heat and light is twice that of hot-dip galvanized steel, and the reflectivity greater than 0.75 is an ideal building material for saving energy.

Galvanized substrate
The electro-galvanized sheet is used as the substrate, and the product obtained by coating with organic paint and baking is an electro-galvanized color-coated sheet. Since the zinc layer of the electro-galvanized sheet is thin, the zinc content is usually 20/20g/m2, so this product is not suitable for use. Make walls, roofs, etc. outside. However, because of its beautiful appearance and excellent processing performance, it is mainly used in home appliances, audio, steel furniture, interior decoration, etc.
