Table1 The type, state and code of the steel tube surface
| Type | State | Code |
| Bright Surface | No coating on the inner and outer surface of steel pipe | SL |
| Copper plated surface | Copper plating on the outer surface of steel tube | Cu |
| Galvanized surface | Galvanized or zinc alloy on the outer surface of steel pipe | Zn |
| Double-sided copper plating surface | The inner and outer surfaces of the steel pipe are plated with copper | Cu/Cu |
| External galvanized inner copper plating surface | Galvanized or zinc alloy on the outer surface of steel pipe, copper plating on the inner surface | Zn/Cu |
| a. Use electroplating, electroless or hot dip plating. b. Manufacture of steel strip with double-sided copper plating, and the quality of the coating at the weld line should be negotiated by both suppliers and suppliers. c. Manufacture of steel strip with double-sided copper plating. | ||
