Some types of steel come out of the kettle with a matte gray finish and others come out of the kettle with a bright and
Does magnesium chloride corrode galvanized steel?
Magnesium chloride can aggressively attack many types of steel, including galvanized steel. Wet magnesium chloride is more aggressive than dry. Magnesium chloride should not be
Rough Surface on Overlapped Area of Progressively Dipped Steel
Why does the overlapped area on some progressively dipped steel have a rougher surface and thicker zinc coating than the other area of the same
Zinc Skimmings
Zinc skimming deposits are usually caused when there is no access to remove the zinc skimmings during the withdrawal of the steel from the galvanizing
Weeping Weld
Weeping welds stain the zinc surface at the welded connections on the steel. Caused by entrapped cleaning solutions that penetrate the space between the two
Surface Contaminant
Surface contaminants will create an ungalvanized area where the contaminant was originally located, and a surface defect may occur. This can be caused by paint,
Striations
Striations are characterized by raised parallel ridges in the galvanized coating, which can be caused by the chemical composition of the steel. Striations, as seen
Sand Embedded in Castings
Sand inclusion defects occur when sand becomes embedded in the castings and creates rough or bare spots on the surface of the galvanized steel. Sand
Runs
Runs are localized thick areas of zinc on the surface. Runs occur when zinc freezes on the surface of the product during removal from the
Rough Surface Condition
Rough surface condition or appearance is a uniformly rough coating with a textured appearance over the entire product. The cause for rough surface condition could
