[0002] Insufficient adhesion of the galvanized layer will cause the galvanized layer to fall off, bubbles and rust will appear on the car body, and the service life will be affected. However, there is no authoritative detection method for the adhesion of the galvanized layer in the industry. Most of them use gravity hammering and repeated bending to see if the galvanized layer falls off. Since there is no clear quantitative definition of the gravity, hammering method, and bending angle, each manufacturer has different detection methods and draws different conclusions.
