Aug 10, 2005 #2 TVP Materials Apr 12, 2002 4,592 Zinc plating plus yellow chromate is commonly specified as 9 micrometers minimum thickness. It can be as low as 5 micrometers if the corrosion requirement is low or as high as 25 micrometers when greater corrosion resistance is required. Upvote 0 Downvote
