Galvanizing Operations


Is there such a thing as lead-free galvanizing?  Galvanizing Association
websites (3 I found) do not seem to discuss lead/environmental issues.

Could lead-free zinc, If there is such a thing, be used or is lead an
integral part of the process with trace amounts always present in the zinc
(or leached into the zinc bath from steel/iron/metal parts being coated)? 

The archives contain several comments mentioning lead/galvanizing - mainly
in terms of lead being added - to achieve a desired surface coating.
Nothing related to lead reduction other than in post-galvanizing processes
(parts washing/machining).

As always, any help or direction would be appreciated.  Happy Holidays, Ric
