DC51D+Z, DC51D+ZF (for bending and forming quality)
DC51D: Used in applications where deep drawing is required but without a need for specific corrosion resistance.
DC51D+Z: Ideal for applications requiring corrosion protection, such as automotive panels, construction materials, and appliances.
DC51D+ZF: Suitable for parts that require not only corrosion resistance but also enhanced weldability and paint adhesion, such as automotive body parts and structural components.
As a professional supplier of galvanized steel plates, GNEE also provides the following steel grades: DC52D, DC52D+Z, DC52D+ZF, DC53D, DC53D+Z, DC53D+ZF, DC54D, DC54D+Z, DC54D+ZF, DC56D, DC56D+Z, DC56D+ZF, etc.

|
|
Chromate treatment is a treatment with an aim to prevent white rusts formed on product surfaces during transportation and storage. |
|
2 Oiling (Y) |
Oiling is to prevent white rusts formed on product surfaces during transportation and storage. |
|
3 Chromate treatment + oiling (LY) |
This treatment with oiling after surface chromate treatment is to further avoid the forming of white rusts. |

Surface Quality of Hot Dip Galvanized Steel
FB(O3)
It is allowed for the existence of small erosion spots, dark spots, strip marks, minor chromate treatment defects and small zinc particles.
FC(O4)
No erosion spot is allowed. However, it is allowed for the existence of light impression, scratches, zinc flow ripple marks, minor chromate treatment defects in small range, while the other side must reach FB requirements at least.
FD(O5)
One side of relatively good quality must further restrict on defects, namely appearance quality after painting is not affected, and the other side must FB requirements at least.
