Color coated steel plate is a kind of composite metal plate, also known as "color organic coated steel plate", which is coated with various protective and decorative coatings after surface treatment with galvanized steel plate or cold rolled steel plate as the base. Color coated steel plate from the inside to the outside of the structural layer is cold rolled, galvanized layer, chemical conversion layer, primary coating (primer), fine coating (front and back paint). This plate surface color novel, strong adhesion, corrosion resistance and decorative, and good processing performance, can be shear, bending, drilling, riveting, crimping and so on. Commonly used coating is divided into inorganic coating, organic coating and composite coating three categories.
After a period of use, the color-coated sheet will be affected by various environmental factors, and its coating performance and service life will be reduced, and it needs to be repainted. The most basic requirement for recoating is to have certain adhesion with the original coating and to have good durability. Outdoor color-coated boards can be divided into 3 categories according to the use environment. The first category is used in the natural environment and requires a certain anti-corrosion effect. Such as: the construction site is under construction, use the color-coated plate to isolate; the second category, used in the natural environment, has a certain anti-corrosion and appearance effect. Such as: prefabricated houses built outdoors; Category 3, used in some harsh environments, requires a certain period of anti-corrosion.
Color coated steel plate is mainly used as building exterior wall panel, directly used to form the wall is required to do the insulation layer; In addition, it can also be used for roofing board, corrugated board, waterproof and gas permeable board, corrosion resistant equipment and components, furniture, car shell, water baffle and so on.
