Hot-dip galvanized base plate
The product obtained by coating organic coatings on hot-dip galvanized steel panels is hot-dip galvanized color-coated panels. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also has an organic coating on the surface that protects and prevents rust, and has a longer service life than hot-dip galvanized sheets. The zinc content of hot-dip galvanized substrates is generally 180g/m2 (double-sided), and the zinc content of hot-dip galvanized substrates for exterior buildings is up to 275g/m2.
Hot dipped aluminum zinc substrate
Hot-dip aluminum-zinc steel plate (55% Al-Zn) is used as the new coating substrate, and the aluminum-zinc content is usually 150g/㎡ (double-sided). The corrosion resistance of hot-dip galvanized sheets is 2-5 times that of hot-dip galvanized sheets. Continuous or intermittent use at temperatures up to 490°C will not cause serious oxidation or scale. The ability to reflect heat and light is twice that of hot-dip galvanized steel, and the reflectivity is greater than 0.75, making it an ideal building material for energy saving.
Electroplated zinc substrate
The product obtained by using an electro-galvanized sheet as the substrate, coating it with organic paint and baking it is an electro-galvanized color-coated panel. Since the zinc layer of the electro-galvanized sheet is thin and the zinc content is usually 20/20g/m2, this product is not suitable for use. Make walls, roofs, etc. outdoors. However, due to its beautiful appearance and excellent processing properties, it can be mainly used in home appliances, audio, steel furniture, interior decoration, etc.
