Zinc Whiskers and electro galvanized steel
2007
Dear Sir,
I have a concern about zinc whisker growth in our computer room. The floor panels are electro galvanized steel. Are these panels capable of producing zinc whiskers? Is there a difference in electro galvanized and electroplated steel?
Thanks

There is no difference between "electrogalvanized" and "zinc electroplated" steel, Steve. Yes it is capable of producing zinc whiskers. Last I read it was believed that hot dip galvanized panels are far less likely to generate whiskers. That is because the whiskers are believed to be a stress relaxation phenomenon and galvanized coatings do not have the stress that electroplated zinc has.
