galvanized steel vs zinc plated steel

galvanized steel vs zinc plated steel

galvanized steel vs zinc plated steel

(OP)
is there a difference, or are they one in the same?  i am working with ~17 gage sheet steel.  thanx.

RE: galvanized steel vs zinc plated steel

They aren't the same.  Galvanizing is "hot dipped" in a pool of molten zinc.  Zinc plated is electroplated.

My experience is that galvanizing is much better for corrosion resistance.

RE: galvanized steel vs zinc plated steel

Electroplating is pretty and yields a nice finish that is acceptable in items that are exposed to the elements when given additional protection, such as painting, etc.  Hot dipped is a stand alone protection that is almost universally used where exposure is constant/critical and other methods of protection are not viable.
If you want maximum protection, hot dipped galvinizing is the 'hot' setup, short of SS.

RE: galvanized steel vs zinc plated steel

The above answers are correct. My comment is that the galvanize process is most suited for mass production, where continuous sheet stock is coated at 100's of feet per minute or fasteners are bulk processed by the ton.  Electroplated zinc is used for custom parts & products requiring machining and fabrication.  Also, zinc plating can be done post-welding and when cutting & drilling leave too many exposed edges on galvanized sheet.
