Introduction of 4 types of color-coated board substrates

Hot-dip aluminum-zinc color-coated sheet 　　

According to requirements, hot-dip aluminum-zinc steel sheets can also be used as color-coated substrates (55% AI-Zn and 5% AI-Zn).
Color coated board

Electro-galvanized color coated sheet 　　

The electro-galvanized sheet is used as the substrate, and the product obtained by applying organic paint and baking is electro-galvanized color-coated sheet. Because 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. outdoors. But because of its beautiful appearance and excellent processing performance, it can be mainly used in home appliances, audio, steel furniture, interior decoration, etc.

Color coated steel sheet for cold-rolled substrate 　　

The color plate produced by the cold-rolled substrate has a smooth and beautiful appearance, and has the processing performance of a cold-rolled plate; but any small scratches on the surface coating will expose the cold-rolled substrate to the air, so that the iron exposed quickly Red rust is formed. Therefore, these products can only be used for temporary isolation measures and indoor materials that are not demanding.

Hot-dip galvanized color coated steel sheet 　　

The product obtained by coating the organic paint on the hot-dip galvanized steel sheet is the hot-dip galvanized color-coated sheet. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also has an organic coating on the surface to protect it and prevent rust, and has a longer service life than hot-dip galvanized sheet. The zinc content of the hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the maximum zinc content of the hot-dip galvanized substrate for building exterior is 275g/m2.
