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;
the hardness meets the standard

Corrosion resistance

The salt spray, heat and humidity resistance, and weather
resistance tests are qualified

Mechanical properties

The bending resistance is good; the impact resistance is strong

Dimensional accuracy

The thickness, width, and length meet the standards; the edges
are straight and have no burrs

Substrate performance

The coating weight meets the standard
(applicable to galvanized substrates)

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.
