DC53D+Z(St04Z) hot dip galvanized plates(coils) are featured with strong coating adhesiveness, high erosion-resistance, accurately controlled zinc coating thickness, high size precision, flat profile and good mechanical, processing and welding performance. They can be used for making outside and inside automotive plates, structural parts and reinforcements.

DC53D+Z(St05Z) hot dip galvanized automotive steel size:
Nominal thickness: 0.30mm~3.0mm, nominal width: 800mm~1830mm
Note: nominal thickness of a plate/strip is sum of base plate thickness and coating thickness.

DC53D+Z(St05Z) hot dip galvanized automotive steel surface treatment:


1 Chromate treatment (L)
 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.

DC53D+Z(St05Z) ensile strain mark:
It is guaranteed that no tensile strain mark occurs on steel plates and strips at their application within 6 months after they are produced.
