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/m2 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.
(1) It has good durability, and its anti-corrosion ability has a longer service life than galvanized steel sheets;
(2) It has good heat resistance and is less likely to change color at high temperatures than galvanized steel sheets;
(3) Has good heat reflectivity;
(4) It has processing performance and spraying performance similar to that of galvanized steel sheet;
(5) It has good welding performance.
(6) Good performance-price ratio, durable performance and very competitive price. Therefore, whether it is architectural designers, engineers or manufacturers, galvanized steel sheets have been widely used in industrial buildings, steel structures and civil facilities, such as: garage doors, gutters and roofs.
