All combining and distributing of auxiliary equipment loads imposed on the building system shall be done in accordance with the applicable section of the 2000 edition of the "International Building Code" published by the International Code Council.

Upon request, the selected building manufacturer shall provide the building purchaser with complete design certification signed and sealed by a registered professional engineer.

Roof Panel Design

Roof panels shall be supplied in a single continuous length from eave line to eave line or ridge line and shall be designed to tightly interlock so that no fasteners are required at intermediate points along the panel side laps.Roof panels shall be 16" or 12" wide with a smooth surface between the interlocking side ribs. The interlocking ribs shall be a minimum 3" high, and shall be turned upward. All roof panels shall be factory punched for connection at the eave line of the building.

There shall be no fastener penetrations through the roof covering except at eave lines, ridge lines and roof accessory openings such as skylights and ventilators.

Finish Option 1

Roof panels shall be nominal ____ gauge galvanized steel conforming to ASTM A-792 specifications with the galvanized coating conforming to G90 (1.25 oz. commercial) standards. Minimum yield strength of the panel material shall be 50,000 PSI.

Roof panels 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 roof 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.

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 (0.9 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.

Exterior color coatings shall meet the following performance standards after 10 years continuous exposure in normal atmospheric conditions not containing corrosive fumes such as chemical fumes 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. 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 type aluminum downspouts. Gutters and downspouts shall be the same color as the building rake trim and shall be complete with all required outlet drops, elbows and connecting hardware.

Eave Trim Option

The eaves of the building shall have a nominal 26 gauge factory painted eave trim of the same configuration and color as the building rake trim. The eave trim shall allow free passage of roof drainage.
