The quality of hardware is not only related to its material, but also closely related to the effect of electroplating. There are many kinds of electroplating, one is rough electroplating. which effect is not very good. It is generally used for bags that do not pay much attention to appearance, and such electroplating also for iron hardware embryos.
The surface effect of the hanging electricity is much better than that of the rolling electricity. The surface of the hardware embryo before the hanging electricity needs to be polished, so the electroplating effect will be smooth and beautiful. If the polishing is not good, the electroplating effect will be very poor. The hardware for hanging electricity will be used for bags of certain grade.
