💡 A Word from JOBPLOY
Since plating and surface treatment sites involve many processes that handle chemicals and use heat, wearing safety protective equipment and following on-site safety rules are essential. As physical work such as transporting heavy bolts or parts and attaching/detaching racks is involved, basic physical strength and meticulous concentration are required. If you follow safety procedures well and cooperate with colleagues to adapt to the work, you can stably learn the practical skills of the plating field.
