Hot dip galvanizing
 

Looking to see if anyone has had this done recently?

When I did my front backing plates about 5 years ago these guys did it. AZZ is buying up all the small/family/local galvanizing shops.

Not sure they want to deal with us small onesy-twosy type guys as they are a large production operation but worth a shot to see if they can help.
