Color coated board
Color-coated plate, also known as color steel plate, color plate in the industry. Color coated steel plate is made of cold-rolled steel plate and galvanized steel plate as substrates, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), coating with paint in a continuous method (roll coating method), baking and cooling Into the product. Coated steel plate has light weight, beautiful appearance and good corrosion resistance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, and electrical industry. Good results such as wood, efficient construction, energy saving and pollution prevention.

The basic concept of color-coated sheet: cold-rolled strip steel and galvanized strip steel (electro-galvanized and hot-dip galvanized) are used as substrates on the continuous line, after surface pretreatment (degreasing and chemical treatment), the coating is applied by roller coating. The plate obtained by baking and cooling one or more layers of liquid paint is the coated steel plate. There are back (primer) paint and top (front) paint coatings in China. Generally, domestic use has one layer of back paint and two layers of top paint, and foreign business has two layers of top paint and back paint. Since the coating can have various colors, it is customary to call the coated steel sheet a color coated steel sheet.

Product Usage
The color coated steel plate using galvanized steel plate as the base plate, in addition to zinc protection, the organic coating on the zinc layer plays a covering and isolation function, which can prevent the steel plate from rusting, and has a longer service life than galvanized steel plate. The service life of steel plate is 50% longer than that of galvanized steel plate. However, in different regions and different parts of use, the service life of color coated plates with the same amount of galvanization, the same paint, and the same coating thickness will be very different. For example, in industrial areas or coastal areas, due to the effect of sulfur dioxide gas or salt in the air, the corrosion rate increases and the service life is affected. In the rainy season, the coating will be corroded quickly and the service life will be reduced if the coating is wetted by rain for a long time, or where the temperature difference between day and night is too large and easy to condense. Buildings or workshops made of color-coated steel plates often 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 larger, it is less likely to accumulate dust and other dirt, and the service life is longer; those areas or parts that are not frequently washed by rain should be washed regularly with water.

Color steel plates are widely used. It has the characteristics of no pollution, excellent weather resistance, corrosion resistance, and high processing. Color steel plates are widely used in construction, home appliances, transportation, packaging, mechanical processing, interior decoration, medical treatment, automobile industry, etc.
