<DIV>Dear David and Gennaro,</DIV>
<DIV><BR></DIV>
<DIV>Brooklyn Bridge Forest is not necessarily any longer looking at
greenheart. As well, it is unlikely that there will be any "sustainable"
source of greenheart, ever. At least, not greenheart that would at all be
durable, since, as I may have mentioned before, other than teak, almost all
the tropical hardwoods imported into the US that are popular because of their
durability get that durability from the fact that the wood is from trees that
are 250 - 1000 years old. That is, they are extremely dense as a result of
their age. Teak, on the other hand, has an inherent oiliness that gives it
extreme durability. This inherent durability can come about even in much
younger tress. The same is true of a few other species (I have mentioned, ad
nauseam, black locust) that have inherent durability when even young. However,
all domestic hardwoods have a Class B or C fire rating and thus do not solve
Gennaro's problem.</DIV>
<DIV><BR></DIV>
<DIV>As far as recycled plastic lumber, I believe that Axion can add a
spray-on fire retardant to their material. However, Axion recycled structural
composites are not necessarily lighter than tropical hardwoods, so I don't
know if that makes them too heavy for Gennaro's situation.</DIV>
<DIV><BR></DIV>
<DIV>I would be happy to contact Axion folks to find out if the
flame-retarding coating is currently available and details about it (including
the weight of the material).</DIV>
<DIV><BR></DIV>
<DIV>Of course, one would have to assess load-bearing capacities vs. profiles,
since this would be different than wood, and then factor that into weight
calculations.</DIV>

sustainable source for greenheart for maintaining the Brooklyn Bridge. I'm
not sure what kind of fire rating greenheart does or doesn't have.
(According to one site I just googled, it carries a "high/medium"
rating.)<BR><BR>David<BR>David Bergman RA LEED AP<BR><FONT
