在热镀锌钢板上涂有机涂层得到的产品为热镀锌彩涂板。除锌的保护作用外，热镀锌彩涂板表面的有机涂层也起到隔离和防锈的作用，其使用寿命比热镀锌板长。热镀锌基板的锌含量一般为180 g/m2（双面）。室外用热镀锌基板的锌含量为275 g/m2。
COLOUR COATING STEEL PLATE FOR COLD ROLLED SUBSTRATE
The color plate produced by the cold-rolled substrate has a smooth and beautiful appearance, and has the processability of the cold-rolled plate; however, any small scratches on the surface of the coating will expose the cold-rolled substrate to the air, thus causing the rapid formation of red rust on the exposed iron. Therefore, these products can only be used for temporary isolation measures with low requirements and as indoor materials.
Hot-dip Galvanized Coating Roll
The product obtained by coating organic coatings on hot-dip galvanized steel sheet is hot-dip galvanized color coated sheet. In addition to the protective effect of zinc, the organic coating on the surface of hot-dip galvanized color coated sheet also plays the role of isolation and protection against rust, and its service life is longer than that of hot-dip galvanized sheet. The zinc content of hot-dip galvanized substrates is generally 180 g/m2 (double sided). The zinc content of hot-dip galvanized substrates for external use is 275 g/m2.
Hot-dip Aluminum-Zinc Coated Plate
Hot-dipped aluminium-zinc steel sheets can also be used as color-coated substrates (55% AI-Zn and 5% AI-Zn) according to requirements.
Galvanized color coated sheet
Using galvanized sheet as base plate and baking with organic paint, the product is galvanized color coated sheet. Because the zinc layer of galvanized sheet is thin and usually contains 20/20g/m2 of zinc, it is not suitable for outdoor wall and roof making. But because of its beautiful appearance and excellent processing performance, it can be mainly used in household appliances, audio, steel furniture, interior decoration and so on.
