Galvanized does not do very well in Hawaii near the water. I haven't
seen much powder coated Al, but anodized AL with SS hardware seems
to work about as good as anything I've seen. We see SS J boxes,
fiberglass boxes seem to break down in the UV after several years,
but painting with the right paint helps a lot. The last job I worked
on there, we had 2 guys paint all exposed J-boxes and PVC conduit
with a heavy duty oil based (messy cleanup) paint. I'll let you know
in 5 years how it all looks.<br>
Also, be sure and get all your conduit clamps and unistrut in
stainless. More expensive, harder to find, and harder to cut, but
you'll see the difference in a couple of years for sure. Just a
single washer that's not SS will stand out like a sore thumb later.<br>

style="font-family: Helvetica,Arial,sans-serif;">Hi Esteemed
Wrenchies,<br>
<br>
So for the project I'm working on in the Bahamas for ground
mount racking - have folks found Aluminum or Galvy to stand up
against salt spray better?<br>
<br>
And if Al - powder coated or anodized?<br>
<br>
And with mixing them - (like a typical Steel Pipe rack with
Al Rails) - are the junctions going to be a problem with lots
of salt?<br>
<br>
Any solution to AL framed modules not turning black and ugly?
Do black anodized module frames help?<br>
<br>
Thanks!<br>
<br>
