Product Introduction and Common Specifications
Color coated coil is a kind of steel coil product made of cold rolled or hot rolled steel plate as the base material, through surface pretreatment, coating and baking curing, etc., with good decorative and anti-corrosion properties. According to the different coating materials, common types of color coated coils include polyester (PE), fluorocarbon (PVDF), reinforced polyester (SMP) and high weather resistance coating (HDP), etc., with thickness usually between 0.12mm and 1.2mm, and width ranging from 600mm to 1250mm. The coating thickness of color coated coil is generally 15μm to 25μm, and the surface color and pattern of each coating can be customized according to customer needs. Common colors include white, blue, red, gray, etc.

Product Application and Advantages
In the construction industry, color coated coils are mainly used for exterior wall decorative panels, roofing materials, doors and windows, etc.; in the home appliance industry, they are used for the shells of refrigerators, washing machines, air conditioners and other products; in the automotive field, color coated coils are used for body accessories and decorative parts; in the electronics and transportation industries, they are mainly used for TV shells, railways, buses, etc. Color-coated coils have become ideal materials for various industries due to their excellent corrosion resistance, decorative properties, good processing performance and weather resistance.
Color-coated coils have many advantages, the most prominent of which is their excellent corrosion resistance. The coating can effectively isolate the steel substrate from the external environment, thereby preventing the steel plate from rusting and oxidation, and is particularly suitable for use in humid or acidic and alkaline environments. Secondly, the decorative properties of color-coated coils are also very strong. The products can be customized in color and pattern according to customer requirements to meet different design needs and are widely used in various architectural styles. In addition, color-coated coils also have good processing properties and can be processed by stamping, bending and other processes to adapt to different manufacturing processes. Weather resistance is also a major advantage of color-coated coils, especially fluorocarbon coating materials, which can resist ultraviolet radiation, high temperature and low temperature changes, ensuring that the product will not fade or crack after long-term use. At the same time, color-coated coils meet modern environmental protection requirements, use environmentally friendly coatings, and meet national environmental protection standards.

Product quality inspection methods
In order to ensure the high quality of color-coated coils, the quality inspection link in the production process is very important. First of all, the steel substrate needs to undergo strict raw material inspection before production to ensure that its surface is flat and meets standard requirements. Secondly, after the substrate is surface treated, its surface cleanliness and the thickness of the phosphating layer need to be tested to ensure the adhesion of the coating. The thickness of the coating is a key indicator of quality inspection. The uniformity and thickness of the coating are regularly checked during the production process to ensure that it meets the design requirements. At the same time, adhesion testing is also very important. Methods such as tape peeling tests are usually used to check whether the coating is firmly attached to the substrate. Corrosion resistance tests, such as salt spray tests and wet heat tests, can verify the anti-corrosion effect of the coating. The appearance inspection of the finished product mainly focuses on color difference, surface defects and other issues to ensure that the appearance quality of each roll of color-coated coil meets the standard requirements.
