RE: Galvanized Material
The lead content can be up to 0.5% on some older HDG components.
The highest zinc lead content used for HDG used to come from Mexico and Italy.
When I worked with zinc we were careful to select our suppliers of the zinc as the lead content caused 'spangle' on thin components. We actually received zinc ingots with lead contents higher than the 0.5% mentioned above that required careful additions to the baths.
I think that in the US the EPA has or is coming out with new guidelines for lead and HDG. I've seen some price increases in HDG that supposedly resulted from lower lead content requirements.
