Spread Index of 0 and a Fuel Contributed Index of 5 or less
when tested in accordance with ASTM E-84 test procedures.
The finish coat shall be a white siliconized polyester
formulation that will meet the following performance
standards after 10 years continuous exposure in "normal"
atmospheric conditions not containing corrosive fumes such
as chemicals or salt spray.
1. Panels shall show no evidence of blistering,
peeling, or chipping.
2. Panels shall not show surface chalking in excess of
the No. 4 rating D659 as established by the
American Society of Testing Materials (ASTM).
3. Panels, after cleaning, shall not show color change
in excess of 7 NBS units when measured in
accordance with the ASTMD-2244 standard.
The above performance standards shall not apply where panels
have been damaged by fire, radiation or other physical
damage.
Finish Option 2
Roof panels shall be a nominal __ gauge steel coated on both
sides with a coating of corrosion resistant aluminum-zinc
alloy conforming to ASTM A 792 specification with the
coating conforming to AZ55 (55%) standard by a continuous
hot dipping process. Coating weight shall be a minimum of
0.50 oz. of aluminum-zinc alloy per square foot of coated
sheet equivalent to about 0.8 mil thickness on each side.
Minimum yield strength of panel material shall be 50,000
PSI.
Wall Panel Design
Exterior wall panels of the building shall be a single
continuous length from the base channel to the roof line of
the building at the sidewalls and endwalls of the building
except where interrupted by wall openings.
Wall panels shall be 16" wide with a 3" deep inward turned
interlocking side rib. Wall panels shall contain two 3/4"
deep by 3-1/8" wide fluted recesses, each starting 2-7/16"
from the panel edge.
Wall panels shall be fastened internally to the base channel
and eave cap of the building with 3/8" diameter
electro-galvanized machine bolts placed within the panel
interlock. The fastening system shall be designed so that
no wall fasteners are exposed on the exterior surface of the
walls.
Wall panels shall be nominal 24 gauge galvanized steel
conforming to ASTM A-653 specifications with the galvanized
coating conforming to G90 (1.25 oz. commercial) standards.
Minimum yield strength of panel material shall be 40,000
PSI. Panel material shall be embossed with a random pattern
pebble embossure of approximately .007 - .008 depth.
All exterior surfaces of the galvanized steel wall covering
and exterior trim shall receive a factory, roller applied,
paint coating having an exterior coating thickness of 0.8 to
1.2 mils of dry film thickness. The finish coat for wall
panels shall be a siliconized polyester formulation of one
of the following Parkline colors: Twilight Blue, Desert
tan, Laurel Green, Arctic White, Harvest Gold, Shell Gray,
or Roman Bronze.
The wall panel color coating shall carry a low fire hazard
rating equal to a Class 1 material as defined by Factory
Mutual. The panel coating shall have achieved a Flame
Spread Index of 0 and a Fuel Contributed Index of 5 or less
when tested in accordance with ASTM E-84 test procedures.

peeling, or chipping.
2. Panels shall not show surface chalking in excess of
the No. 8 rating D659 as established by the
American Society of Testing Materials (ASTM).
3. Panels, after cleaning, shall not show color change
in excess of five (5) NBS units when measured in
accordance with the ASTMD-2244 standard.
The above performance standards shall not apply where panels
have been damaged by fire, radiation or other physical
damage.
Building Type
Each building shall have a gable roof with a minimum slope
of 2" in each 12" of building width. Roof panels shall be
fastened to the eave cap with 1/4" diameter Type 430
stainless steel bolts through factory punched holes. The
ridge of the roof shall be a welded double channel assembly
capped with a nominal 20 gauge steel cover.
Strap or channel bracing components shall be placed across
the building width to allow transmission of the horizontal
wind loads. All wind bracing components shall be of nominal
14 gauge galvanized steel.
Where required for proper transmission of lateral wind
loads, structural frame wind bents shall be installed. Wind
bents shall consist of a prime painted column and rafter
bolted assembly made of steel conforming to ASTM A-36
specifications.
The interlocking panel roof system shall extend a minimum of
8" over the endwall panels and a minimum of 6" over the
sidewall panels of the building, except buildings with 6"
high rib roof panels shall have no endwall overhang.
The building roof liner shall be finished with nominal 26
gauge factory painted rake trim having matching ridge and
eave cornices. Color of rake trim and cornices shall be
Arctic White or Roman Bronze.
Gutter Option
The eaves of the building shall have a gutter and downspout
system of nominal 26 gauge factory painted gutters of the
same configuration as the building rake trim and 2" x 3" box
