Black zinc-plating

steelISO 13485for bolts

This product is a high-quality black zinc plated metal bolt, which is a customized product for a Canadian customer to meet the customer's customized requirements. It has excellent corrosion resistance and strong mechanical strength to ensure stable performance in various complex environments. Processing technology: cold heading process and stamping proces Product Advantages 1 Excellent corrosion resistance: The black zinc electroplating layer effectively prevents the bolts from rusting in a humid environment and prolongs the service life. 2 High strength and high hardness: The cold heading process gives the bolts excellent mechanical properties, ensuring that they still perform well under high stress conditions. 3 Customized design: The head is bent according to customer needs to ensure that the bolts can perfectly fit specific application scenarios. This black zinc-plated metal bolt is widely used in occasions that require high corrosion resistance and high strength, such as construction engineering, machinery manufacturing, automotive industry and other heavy equipment fields. what is black zinc plated Black zinc plating is a surface treatment process used to enhance the appearance, corrosion resistance, and durability of metal parts. 1 Cleaning: The metal part is thoroughly cleaned to remove any dirt, oil, or oxidation that could interfere with the plating process. 2 Acid Pickling: The part is submerged in an acid solution to remove any remaining surface oxides and prepare it for plating. 3 Zinc Electroplating: The part is then placed in a zinc electroplating bath, where a layer of zinc is deposited onto the metal surface through an electrochemical process.
