MATERIALS GLOSSARY (Definitions & Applications)
Painted aluminum surface (two sides) with a corrugated
plastic core. It serves as a lightweight alternative
to plywood for sign painting and vinyl graphic applications.
Available in 1/4” only. It will not rust, swell,
or delaminate and is impervious to water. These features
make it perfect for all outdoor, or UV-exposed indoor
.040 gauge aluminum painted on one side with flat white
back. Extremely light weight for sign painting. Denting
is possible. This product is discontinued. Limited to
stock currently on-hand.
Rigid PVC expanded vinyl that offers an exceptional
variety of usages (mostly sign-making). No priming is
necessary and it will not rot or delaminate. Direct
sunlight may cause panel to misshape. It is economical
when compared to other sign materials. Also sold for
such applications as shower enclosures and is FDA approved

1/8" version of alumalite. It is painted aluminum
surface with corrugated plastic core (good one-side)
white aluminum face with a flat silver back. Great for
wall mounts, photo mounting, billboard fascias and signs.
Great alternative to traditional aluminum sheets and
is 100x’s more rigid. Discontinued (see polymetal).
Tempered masonite (compressed pressed wood) hard throughout
entire board. All that we carry is perforated (peg-board).
H.D.O.: High density overlay panel designed
for applications of reflective film for hi-way signs;
it is ideal for state, county and municipal signage.
Every veneer layer is solid and care is taken to minimize
core gaps. There is no preparation before applying film
or paint. Excellent for vinyl graphic applications.
Board: Exterior fir plywood with 15 gauge white
painted aluminum on both sides. Premium inner plies
with smooth, tight, sanded veneers that are less likely
to have gaps or voids in the inner-ply’s. Great
for post and rail signs, signs that use cutout shapes,
portable sidewalk displays, sandwich boards, hanging
signs and a-frames. Edges must be end capped.
(Guardian): Medium density paper overlay on
top of exterior fir plywood for sign painting, or exterior
construction, has a nice paintable surface. This two-step
process includes the plywood substrate being sanded
before M.D.O. overlay is applied to minimize wood grain
and patch show-through. This is our standard grade of
M.D.O. and grain telegraphing is more prevalent than
in our Signal board.
(Signal): Premium grade Medium density paper
overlay, the core is exterior fir plywood with an outer
layer of exterior luan on front and back (under paper
overlay) to prevent grain telegraphing. The signal grade
uses premium face veneers and a solid core. Offers fewer
(and tighter) core gaps giving the least amount of edge
voids for better machineability and weatherability in
cut shape applications. Mostly used for applications
where smooth painted surface is essential.
(Primed): M.D.O. primed (grey primer applied
in anticipation of first layer of paint). High performance
overlay impregnated with a thermoset acrylic primer.
This helps reduce production time and provide a uniform
prime coat. Available in Guardian and Signal.
