Hot dipped galvanized steel strip
Processing Of Galvanized Steel Strips:
Galvanized steel strips is products which is produced by galvanizing cold rolled steel coils. It is the process of coating steel with a thin zinc layer, by passing metal through a molten bath of zinc at a temperature of around 460℃. And galvanized steel strips is wildly used in the applications where rust resistance is needed.
Standard Of Gavanized Steel Coils:
The standard of galvanized steel strips varies according to different countries, but which is major used as per EN,JIS,GB and ASTM.

Steel Grade Of Galvanized steel strips:
Standard of galvanized steel strips as per EN 10327, then the steel grade of galvanized steel strips can be DX51D, DX52D,DX53D,DX54D,DX56D,DX57D.
Standard of galvanized steel strips as per GBT2518, then the steel grade of galvanized steel strips can be 01, 02, 03, 04, 05, 06.
Standard of galvanized steel strips as per JIS G3302, then the steel grade of galvanized steel strips can be SGCC, SGCH, SGCD etc..
Standard of galvanized steel strips as per ASTM A653, then the steel grade of galvanized steel strips can be CS, FS, DDS, EDDS, SS etc..
Different steel grade of galvanized steel strips means different drawing quality.
Zinc Spangle Of Galvanized Steel Strips:
Regular Spangle: The finish produced on hot dipped galvanized steel strips in which there is a visible multifaceted zinc crystal structure.
Minimized Spangle: The finish produced on hot dipped galvanized steel strips in which the grain pattern is visible to the unaided eye, and is typically smaller and less distinct than the pattern visible on regular pattern.
Spangle Free: The finish produced on hot dipped galvanized steel strips in which the visual spangle pattern is not visible to the unaided eye.
