Coating Thickness
Why does the galvanized coating thickness depend on the steel thickness?
The hot-dip galvanized coating is an intermetallic layer of iron and zinc, meaning the zinc and iron react and diffuse into one another to create
What types of metals will not galvanize?
There are many types of materials that will not develop a galvanized coating. Iron is necessary for a galvanizing reaction to happen, so if you
Is there concern about galvanic corrosion when different types of zinc-coated steel are in contact?
There is not a concern of dissimilar metals corrosion (galvanic corrosion) when pairing zinc-coated steel of different types (for example when pairing a hot-dip galvanized
Is it possible to have steel with chemistry that is too good for galvanizing?
It is possible to have steel chemistry with levels of silicon and phosphorus that are too low to meet the minimum thickness levels specified in

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
Can 4130 steel be successfully galvanized?
4130 steel is a chromoly steel. Steels of this chemistry have presented some adherence problems in the past when galvanized. The galvanized coating developed in some
Measuring Zinc Coating Thickness of Hot-dip Galvanized Steel
Coating thickness is tested by using a magnetic thickness gauge. There are three types of magnetic thickness gauges: pencil-style, banana-style, and electronic. Electronic thickness gauges
Coating Thickness vs. Coating Weight
The usual criterion for determining the expected service life of zinc coatings is thickness: the thicker the coating, the longer the service life. This is
