Surface Treatment Of Different standards Gi Steel Coil
|
Surface Treatment |
Feature |
|
Chemical Treatment |
minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |
|
retain the bright metallic luster for a long period |
|
|
Oil |
minimize the tendency for humid-storage stain |
|
Chemical Treatment and Oil |
The chemical treatment provides very good protection against humid-storage staining, while the oil provides lubricity for operations. |
|
Dry |
must be transported and stored with special precautions to preserve low-humidity conditions. |
|
Anti-finger print |
minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |
Application Of Different standards Gi Steel Coil
Features Of Different standards Gi Steel Coil
1. Resistance to Corrosion Has better performance in corrosion resistance than hot dip galvanized coil/sheet of the same thickness and its service life is 1-5 times longer than general hot dip galvanized coil/sheet. 2. Machinability Can satisfy the processing requirements of rolling, coiling and others processes alike. 3. Thermal Resistance Can sustain the environment at 315°C for long time.
