|
| Surface of the original sheet is smooth. Hence, good painting surface is secured and it makes zinc coating uniform to make beautiful surface. Especially, in case of phosphate processing, it has excellent paint adhesion. Therefore, the characteristic is proper for any paint and painting method. |
|
 |
|
| Outstanding corrosion resistance with uniform plating layer because zinc is electrically adhered on the material metal (fine film of alkaline zinc carbonate will be formed if it is exposed in the air). In case of phosphate material, fingerprint resistance material, Cr-Free fingerprint resistance steel sheet, they have more excellent characteristic. |
|
 |
|
| Weldability is not good because contact area of Galvanized steel sheet is wide during welding force and electrical conductivity is poor comparing to CR steel sheet. However, welding is easiest among coated steel sheets and SPOT welding and SEAM welding are possible. |
|
 |
|
| Coating weight is smaller comparing to metal coated steel sheet and there is no thermal effect during manufacturing process. Hence, material characteristic and machinability of same level with that of CR which is original material can be secured. |
|
 |
|
| Product for which film properties is secured by separately treating fingerprint resistance resin without treating phosphate coating that is non-conductive film. It has excellent electrical conductivity because electrical surface resistance is below 0.1mΩ. |
