Note: The surface treatment process of the product is divided into two types: electroplating and spraying. Gold, silver, and brass surfaces are electroplated. Black is sprayed. Due to the characteristics of the process, electroplating and spraying need to be hung up for processing, and inevitably one of the inner edges of the finger hole will have an electrical contact point and a spray hanging point. The contact and hanging points of this product are located on the inner edge of the finger hole, which has less impact on the overall product; it is inevitable that there will be minor scratches and mold marks, polishing and grinding marks on the electroplated surface and paint surface of metal products, please be aware! Dear friends who mind, please think twice before placing an order with perfectionists;

The product is cast in one piece of zinc alloy, and the die-cast zinc alloy has good mechanical properties at room temperature. However, the tensile strength at high temperature and the impact performance at low temperature are significantly reduced, and it is not suitable for use in high and low temperature (below 0??) working environments. Note: Please pay attention to the maintenance of metal products. In high salt, high alkali, and high acidity environments, the product is prone to rust. For long-term storage, please wipe off the sweat left on the surface. If necessary, a layer of motor oil can be applied to the surface to form an oil film to isolate air oxidation.
