Note: The product surface treatment process is divided into plating and plastic spraying. Gold, silver surface plating treatment. Black is sprayed. Because of the characteristics of the process, plating and plastic spraying need to hang up the processing; inevitably, one of the inner edges of the finger holes will have an electrical contact point and a plastic spraying point. This product contacts a hanging point selected in the inner edge of the finger hole so that the overall impact on the product is less; metal products’ plating surface and paint will inevitably have minor scratches and mold marks, polishing, and grinding traces; please note!

Products from the zinc alloy casting and die-casting zinc alloy at room temperature have better mechanical properties. But in high-temperature, tensile strength, and low-temperature, impact properties are significantly reduced and should not be used under the working environment in high and low temperatures (0 ℃ below). Note: Please pay attention to the maintenance of metal products in high salt, high alkali, and high acidity environments, as they will quickly lead to product rust. For long-term storage, please dry the surface of the hand’s residual sweat. If necessary, you can put a layer of machine oil on the surface to form an oil film to isolate the air oxidation.
