Color coated sheet is a product made of cold-rolled steel sheet and galvanized steel sheet as the base material, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), continuous coating (rolling method), baking, and cooling. The main production process of the ordinary double-coating and double-bake continuous color coating unit is uncoiling, pre-coating, baking, and coiling.
Features of color coated sheet：
Suitable for cutting, bending, roll forming, stamping, dustproof, antibacterial, film, metal steel plate is the surface material of modern decoration because of its anti-mildew treatment. The color-coated plate is acid and alkali resistant, and the bottom metal has good corrosion resistance and acid and alkali resistance, so the color-coated plate has excellent chemical resistance.
The fire-resistant PVC high temperature composite board uses a unique fire-resistant PVC film material, which is a flame-retardant material, and the fire-resistant grade reaches B1. With self-extinguishing performance, it can prevent long-term burning; durability, excellent adhesion between the film and the metal steel plate has withstood the test of time, the surface film is easy to maintain and very economical.
The weather resistance of the color-coated board can be added with an anti-ultraviolet formula, which will not change color after many years of use. Color-coated panels are environmentally friendly. Products made of PVC coated steel plates are easy to clean, scratch-resistant, reduce maintenance costs and labor costs, and are environmentally friendly and user-friendly products.
Application of Color Coated sheet:
In addition to zinc protection, the organic coating on the zinc layer plays a role of covering and isolation, which can prevent the steel plate from rusting and has a longer service life than galvanized steel. For example, in industrial areas or coastal areas, due to the effect of sulfur dioxide gas or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, where the coating is soaked in rain for a long time, or where the temperature difference between day and night is too large, it will quickly corrode and shorten the service life. Buildings or cars made of color-coated steel plates usually have a long service life when they are washed by rain, otherwise they will be affected by the effects of sulfur dioxide gas, salt and dust. Therefore, in the design, if the slope of the roof is large, it is unlikely to accumulate dust and other dirt, and the service life is longer; for those areas or parts that are not often washed by rain, they should be washed regularly with water.
