[TowerTalk] galvenizing vs painting a tower platform

[K4VV@aol.com]

I have had very good experience for 8 years with ZRC Cold Galvanizing of 
several towers.  ZRC advertises that they have the only such product approved by 
the US Government as equivalent to hot dip treatment.  I used steel brush or 
sandblasting preparation for any rusted surface.  

Two coats of ZRC hold up well.  No rust has shown up anywhere that was 
properly prepared.  The ZRC seems to be more vulnerable to abrasion (e.g., lifting 
with a steel chain) than hot dip surfaces. 

ZRC seems easy to apply with a roller, brush or mit.
