The quality of the locks is mostly electroplated, the coating is fine and smooth, even and moderate, the color is bright, and there are no signs of bubbles, rust and oxidation. The surface treatment of the lock is not only for the sake of beauty, but also relates to the service life and quality of the lock. Therefore, for a good lock, the surface treatment must be passed.
