Yeah
so
I
have
a
question
on
I
looked
at
the
prices
of
those
a
few
years
ago,
and
at
that
point
the
cost
of
the
entire
group
glazing
structure
was
doubled
over
the
polycarbonate.
So
so
the
aluminum
extrusion
trim
doubles
the
price
essentially
and
I
was
thinking.
Maybe
we
can
use
very
simple
steel
strips
that
are
painted
for
corrosion
resistance,
but
basically
long
steel
strips
which
will
get
the
price
of
those
the
trim
on
that
down
by
a
factor
of
about
ten
or
so
so.
A
That's
one
thing
we
might
want
to
consider
anyone
who
is
listening
to
this
if
you've
got
any
ideas,
but
the
figure
appears
to
be
about
for
any
panel.
The
trim
for
for
bonding
bounding
any
panel
adds
pretty
much
twice
the
price
for
the
16
foot
long
before
but
16
by
four
foot.
Long
panels
be
interested
in
comments
about
that.
If
anyone
has
any.
A

B

A
That
you're,
just
pressing
down
we've
done
that
before
with
when
we've
done
it,
we've
done
the
polycarbonate
panels.
What
we
did
was
actually
use
wooden
wooden
trim
to
do
that
with
loaded
was
not
a
problem
with
metal.
We
can
control
the
pressure
that
we
screw
down.
The
polycarbonate
is
actually
very
strong,
I
mean
have
you?
Have
you
worked
with
that?
Yes,.
