RE: Weather proof paint

[Subject Prev][Subject Next][Thread Prev][Thread Next]
That is a very difficult question without knowing the expected life span, the in-situ conditions, and the potential corrosion agents. 
 
As someone suggested, a coating on galvanizing is a very good, aesthetically pleasing system.  It is called a duplex coating.  The polyurethane's are very effective, but lack significant abrasion resistance.  There are other systems that are coal tar epoxy based that you could also consider.

I have a project we called out galvanize for structural steel.  The owner does not like the galvanize.
What type of paint or power coat that can be used in lieu of galvanize?  What is the ASTM number?
TIA
