E. Structural Steel
Provide internal structural steel as
required to meet the requirements
of the permanent installation.
F. Fasteners
Unless otherwise indicated, provide
concealed fasteners fabricated from
metals that are non-corrosive to
either the signage materials or the
mounting surface.
G. Electrical/Lamps
Provide new electrical components
and respective lamps, so as to be
easily repaired or replaced from local
available stock (24 hr. max. turn-
around).
H. Vinyl Machine-Cut Copy
Vinyl machine-cut copy shall be of
3M Scotchcal brand film or approved
equal.
I. Paint
Paint shall be contractor’s highest
grade for best ultraviolet light
resistance, weatherability, and
overall longevity of finish and color.
Where possible, use water-based,
100% solids, high performance
acrylic instead of solvent-based
paints. If solvent-based paints
must be used, use products that
are low-VOC (<380 g/l) and <1%
aromatic hydrocarbons by weight.
Paint shall have a written warranty
against premature fading and be
approved by Design Workshop prior
to construction. Prior to close-out,
contractor shall turn over to Owner
3 copies of complete paint schedule
indicating all colors used.
J. Graffiti Clear Coat
All painted sign panels shall have
Matthews Paint Company 6178SP
High Performance Clear coat.
3.5 VOC high gloss clear which
offers outstanding chemical,
graffiti resistance and produces an
unsurpassed hard, durable finish
with excellent gloss, scratch
& chemical resistance.
K. Corten Steel
ASTM A 242: Alloy has a yield
strength of 50,000 pounds per
square inch (340,000 kPa) and
ultimate tensile strength of 70,000
psi (480,000 kPa) for light-medium
rolled shapes and plates up to 0.75
inches (19 mm) thick. It has yield
strength of 46,000 psi (320,000 kPa)
and ultimate strength of 67 ,000 psi
(460,000 kPa) for medium weight
rolled shapes and plates from 0.75–1
inch (19–25 mm) thick. The thickest
rolled sections and plates – from
1.5–4 in (38–100 mm) thick have
yield strength of 42,000 psi (290,000
kPa) and ultimate strength of 63,000
psi (430,000 kPa).
L. Exterior Grade High Pressure
Laminate
High Pressure Laminate (HPL) is a
combination of specially developed,
digitally imaged paper which
is impregnated with melamine
resins, a special UV resistant
overlaminate, and layers of phenolic
resin-impregnated kraft stock, all
pressed under intense pressure and
heat. This process fuses the layers
together into a very durable, solid
core product. Output resolution:
2400 dpi. Matte finish. Warranty: 10
years.
M. Concrete Base Type 1
Form-facing panels that will provide
continuous, true, and smooth
concrete surfaces. Furnish in largest
practicable sizes to minimize number
of joints.
VII. FABRICATION
A. Copy Application
Provide copy to comply with the
requirements indicated for size,
style, spacing, content, position,
material, finish and color of letters,
numbers, symbols and other graphic
devices.

E. Ultra-Violet/Fading Protection
Contractor shall utilize materials,
coatings and processes to minimize
as much as possible any noticeable
fading of pigmented coatings.
VI. MATERIALS
A. Acrylic Color Translucent Sheet
Where sheet material is indicated as
a “color” provide color translucent
sheet of density required to produce
uniform brightness without halo-
like effect. Material provided shall
be appropriately matched to the
intended permanent field conditions.

Where sheet material is indicated
as “clear” provide colorless sheet in
gloss finish, with light transmittance
V. FINISHES
A. Colors and Surface Textures
All colors shall match exactly the
color and finish requirements
provided by Design Workshop. For
exposed signage, materials with
applied colors or other characteristics
related to appearance, contractor
shall provide color matches
