Classification and Use of Color Plates
(1) According to the substrate of color steel plate, it can be divided into cold-rolled substrate color coated plate, hot-dip galvanized substrate color coated plate, and electroplated galvanized substrate color coated plate.
(2) According to the color requirements of the color steel plate, it is divided into many types, such as orange yellow, milk yellow, deep sky blue, sea blue, and crimson
Brick red, ivory, porcelain blue, etc.
(3) According to the surface condition of color steel plates, they can be divided into coated plates, embossed plates, and printed plates.
Cold rolled substrate color coated plate
Color plates produced from cold-rolled substrates have a smooth and beautiful appearance, and possess the processing performance of cold-rolled plates; However, any small scratches on the surface coating will expose the cold-rolled substrate to the air, causing the exposed iron to quickly form red rust. Therefore, these types of products can only be used for temporary isolation measures with low requirements and as indoor materials. Hot dip galvanized color coated plate
The product obtained by coating organic coating on hot-dip galvanized steel plate is hot-dip galvanized color coated plate. In addition to the protective effect of zinc, the organic coating on the surface of hot-dip galvanized color coated sheet also provides insulation protection and prevents rust, resulting in a longer service life than hot-dip galvanized sheet. Commonly used for building exterior walls and tile roofs.
Hot dip aluminum zinc color coated plate
According to the requirements, hot-dip aluminum zinc steel plates can also be used as color coated substrates (55% AL-Zn and 5% AL-Zn). Aluminum zinc plated sheet is a high corrosion resistance material that has stronger corrosion resistance than galvanized sheet. Similar to hot-dip galvanized color coated sheet, it is commonly used for building exterior walls and tile roofs.
* Electroplated galvanized color coated plate
The product obtained by baking electroplated galvanized sheet with organic coating is electroplated color coated sheet. Due to the thin zinc layer of electroplated sheet, this product is not suitable for outdoor production of walls, roofs, etc. However, due to its beautiful appearance and excellent processing performance, it can mainly be used in household appliances, audio systems, steel furniture, interior decoration, etc.
