[TowerTalk] Non-metallic towers and guy wires

[Jim Lux]

Most any structural shape you care to name is available as "pultruded"
fiberglass reinforced plastic. A notable tradename is Extren. Lots of grades
for various purposes.  Structurally, think of it as aluminum.. it's about
the same cost and strength, but about twice as flexible. There's a special
epoxy that you use to bond it, sold by the same metal dealers that sell the
stuff.

As for towers made out of composites, I suspect that a call to the mfr of
Extren (Ryland?) would turn up folks who make assemblies.  There's also
structural fiberglass tubing in a variety of sizes and wall thicknesses.

I've used a lot of Extren building high voltage equipment.  Easy to work
with, except for all the usual composite problems (steel blades go dull
instantly, little itchy fibers everywhere, etc.)
