We understand that each customer has unique needs, so we offer personalized customization services.
1. Dimension customization: We can customize different diameters, lengths, and cross-sectional shapes according to customer requirements. For example, for the manufacturing of some special mechanical parts, specific diameters and lengths of bars may be needed to meet assembly requirements; in some special structural designs, non-circular cross-sectional shapes such as square and rectangular can also be customized to optimize the mechanical performance and spatial layout of the parts.
2. Customized surface treatment: Different surface treatments can be applied to the rods to meet various usage scenarios and functional requirements. Common methods include mechanical polishing and electrochemical polishing to enhance surface smoothness, reduce friction and corrosion. Coating treatments can also be carried out, such as applying special protective coatings, to further improve their corrosion resistance, wear resistance or oxidation resistance.
3. Customized packaging: According to the transportation and storage requirements of customers, different packaging forms can be customized. For long-distance transportation or situations with high demands for rust and moisture prevention, special anti-rust packaging materials and sealed packaging methods can be adopted to ensure that the rods are not damaged or corroded during transportation and storage.
