[TowerTalk] cutting galvanized tower legs

[Gary Slagel]

Hi guys,
 
My triex w51 crankup folded over in a windstorm the other day.  I'm going to have to do some cutting on it to get it all the way down and apart.   
 
What is the best way to cut this stuff?  Is there a metal cutting blade I can put in a circular say?  Some kind of metal cutting disk I can use with my handheld disk grinder/sander?  
 
Thanks for advice.
