What are the inspection standards for color-coated coils?
Color-coated coils are a type of metal material with high decorative, corrosion-resistant and weather-resistant properties, and are widely used in the fields of construction, home appliances, and automobiles. The inspection standards for color-coated coils mainly include the following aspects:
Inspection items | Specific standards |
Appearance quality | The coating is flat, smooth and has no defects; the color is uniform and there is no color difference |
Coating performance | The thickness is compliant; the adhesion is strong; |
Corrosion resistance | The salt spray, heat and humidity resistance, and weather |
Mechanical properties | The bending resistance is good; the impact resistance is strong |
Dimensional accuracy | The thickness, width, and length meet the standards; the edges |
Substrate performance | The coating weight meets the standard |
These inspection standards ensure that the color coated coils meet the application requirements in terms of quality, performance, appearance, etc., and can meet the different needs of customers.
