Coloured steel sheet is a kind of steel sheet which is coated with cold rolled strip and galvanized strip (galvanized and hot galvanized) as its base plate. It is prepared by surface pretreatment (degreasing and chemical treatment), rolling coating, one
or more layers of liquid coating, baking and cooling. Because paints can have different colors.
The advantages of using color coated steel plate: color coated steel plate: because the production process of color coated steel plate is strictly controlled, the uniformity of quality is guaranteed in appearance, durability and workability. Coated steel plates produced in large quantities are inexpensive. Compared with the coating treatment method, the coated steel plate has higher solid content, lower loss of organic coating and better economy.
The application of coated steel sheet can greatly simplify the processing technology, and there is no environmental pollution caused by chemical treatment, coating, baking, etc. Generally selected coatings are epoxy, polyester, silicon modified polyester, polyvinylidene fluoride, polyurethane and so on. We will choose according to different application environments and uses.
Colored coated steel plates with different substrates or coatings are selected for external use. Hot dip galvanized substrates with color coated steel sheets should be selected. The number of galvanized steel sheets usually exceeds 180 g/m (double sided). Polyvinylidene fluoride paint should choose light and color to keep for 10 to 20 years.
When used as corrugated cardboard in construction, it is better to use two-layer and two-time baked color-coated steel plate on both upper and lower surfaces. When making sandwich panels, the upper surface is coated with two coatings. The utility model has the advantages of light weight, beautiful appearance, outstanding anti-corrosion performance, and can be directly processed. Therefore, it can be widely used in the construction industry, shipbuilding industry, automobile manufacturing industry, furniture industry and electrical industry. Industry, etc.
