How to judge the quality of color coated coil?(1)

Released on May. 08, 2018

1. Observe the thickness of base material and film

Color coated coil is composed of base material and colorful film or cladding material. The first thing to consider is the thickness of base material and film. The thickness of base material can significantly impact the service time of color coated coil. If the coil manufacturer reduce the production cost of color coated coil by changing the base material and film, that is, reducing the thickness of base material and adding the thickness of film, the service time of color coated coil can be greatly decreased.

2. Listen to sounds

Use finger or hard objects to knock on pre-painted galvanized/galvalume coil. Dull or not obvious metal sound stands for poor texture. Pretty loud and silvery metal sound means good texture.
