On behalf of a friend on another discussion list:
 
Can anyone provide any information on the introduction and use of
corrugated metal panels as building/roofing materials?
 
When and where were such panels first manufactured and used?
 
Who were the most prominent manufacturers of stamped corrugated panels
and rolled corrugated panels respectively?
 
When was galvanizing of such panels first applied?
 
Any information would be gratefully received.
 
Thanks in advance,
