The outer shell of professional stage electric hoists undergoes a special matte reflective coating treatment: formulated with a unique recipe and applied through a precise spraying process, this coating forms a rough yet uniform matte surface. When stage lights illuminate it, the light scatters in all directions instead of reflecting concentratedly, thereby significantly reducing the intensity of reflected light.
This ensures that the lighting always serves the stage performance itself without causing negative impacts on the audience's viewing experience. Stage electric hoists produced by regular manufacturers use high-quality dedicated matte reflective coatings. Prior to spraying, strict surface pretreatment processes such as derusting, degreasing, and phosphating are conducted, which greatly enhance the coating's adhesion and durability, enabling it to withstand regular handling, installation, and operation in stage scenarios. However, even such high-quality coatings cannot resist damage caused by severe collisions. During the busy periods of stage setup and teardown, if workers operate improperly, resulting in violent impacts between the electric hoist and metal trusses, stage equipment, or the ground; or if the hoist frequently undergoes high-intensity friction with other components during long-term use, the structural integrity of the surface coating will be directly damaged, leading to coating breakage and peeling. In addition, some teams fail to take adequate protective measures during equipment transportation, allowing the hoists to be directly stacked and squeezed with other heavy objects, which can also cause coating peeling. It is evident that for regular stage electric hoists, severe collisions resulting from improper human operation are the primary cause of coating peeling.
