The quality of the bank decorative wall panels can be assessed from both internal and external aspects. The internal quality primarily checks the hardness of the surface and the strength of the bonding between the base material and the surface finish. High-quality products have a hard surface finish, are impact-resistant, wear-resistant, and can be tested with a small knife.

The surface should be free of visible scratches, and there should be no separation between the surface and the base material. The appearance quality is mainly assessed by the degree of realism; high-quality products feature lifelike patterns, uniform processing specifications, easy assembly, and excellent decorative effects.
