Sheet Metal Gauges
There
are
sheet
metal
gauge
charts
all
around,
but
I
wanted
to
do
one
of
my
own.
Gauge
charts
contain
the
standard
sizes
and
their
decimal
equivalent.
But
in
the
real
world
the
sizes
are
different.
When
calculating
developed
lengths
and
specially
if
you
are
creating
3D
models
of
sheet
metal
parts
it
is
“ALWAYS
BEST”
to
use
the
actual
thickness
of
the
material.
For
example,
I
don’t
know
how
many
times
I
get
a
3D
model
that
is
16GA
cold
roll
steel
and
the
engineer
used
a
thickness
of
either
.060
or
.063,
not
know
that
in
the
real
world
that
steel
sheet
is
going
to
be
more
like
.055
or
.056
thick.
