OVERVIEW

The 1" Snap-Loc is a metal roof panel formed from 24 gauge. The panel can be applied on to solid sheeting with or without insulation. Width from 300 mm (12") to 400 mm (16") wide with a 22 mm (1") height at the male rib. Panels are continuous with no end laps.

SYSTEM DESCRIPTION

General: Metal panels employ a hidden fastening system for securement to a solid substrate. 1" Snap-Loc design allows the panel seams to interlock without having to use a mechanical seaming device.
Range of application: on wood or metal sloped roofs; in commercial, institutional, industrial and residential construction; for re-roofing or new construction.
Fasteners (Screws): Fasteners (screws) used to attach panels to plywood deck to be No. 8 by 22 mm (1") panhead. Fasteners to be placed a maximum of 600 mm (24") on center.
Fabrication: Unless otherwise shown on drawings or specified herein, fabricate panels in continuous one piece lengths and fabricate flashings and accessories in longest practical lengths.
Deck Requirements: in keeping with the Standard for Architectural Sheet Metal (ASM) Systems.

DELIVERY, STORAGE & HANDLING

Protect against damage and discoloration.
Handle panels with non-marring slings.
Do not bend panels.
Store panels above ground, with one end elevated for drainage.
Protect panels against standing water and condensation between adjacent surfaces.
If panels become wet, immediately separate sheets, wipe dry with clean cloth, allow to air dry.

FIELD MEASUREMENTS

Verify prior to fabrication.
If field measurements differ from drawing dimensions, notify Architect / Professional Engineer prior to fabrication.

PROTECTION

Treat, or isolate with protective material, any contacting surfaces of dissimilar materials to prevent electrolytic corrosion.

SITE CONDITIONS

Minimum roof slope is 1:4 (3" in 12"). Severe conditions (heavy snow or ice) minimum slope is 1:1.5 (8" in 12").
Verify that structural deck to receive panels is complete, in true plane, secure and otherwise properly prepared.
Prior to starting work, notify General Contractor about defects requiring correction.
Do not start work until conditions are satisfactory.

PERFORMANCE REQUIREMENTS

Wind Uplift Resistance: Panel securement shall conform to the requirements in Part 3 of the Standard for Architectural Sheet Metal (ASM) Systems.
Materials:RoofStar (RGC) accepted metal panel systems shall be formed of steel conforming to the requirements published in Section 9.2. of the Standard.

-:.1 <u>Wind Uplift Standards:</u>
-:National Research Council (NRC-CNRC) Report No. B1040 Wind Uplift Resistance of Metal Roofing. The NRC-CNRC Report No. B1040 test results confirm that an acceptable level of wind uplift resistance can be achieved with RGC Accepted Metal Panel Systems on typical roof designs over solid decking for Most British Columbia geographical locations. Refer to Appendix II for calculations for typical roof wind uplift pressure requirements for buildings located in the Province of British Columbia.
-:A simplified design procedure developed by NRC-CNRC for selecting wind pressure calculations for metal roof assemblies by region (location) and building height in the Province of British Columbia is provided in TAB 8.1.5 to assist designers.
-:RGC accepted metal panel systems shall be formed of steel conforming to one of the following material specifications, as applicable:
-:* ASTM Standard Specification A653 / A653M, Sheet Steel, Zinc-Coated (Galvanized) or Zinc-Iron Alloy Coated (Galvannealed) by the hot dip process, minimum Grade 33, with a design thickness of 24 gauge. (0.024") or greater and a minimum zinc coating designation Z275 (G-90).
-:* ASTM Standard Specification A792 / A792M, Steel Sheet, 55% Aluminum-Zinc Alloy-Coated by the Hot-Dip Process, minimum Grade 33, with a design thickness of 24 gauge (0.024") or greater and minimum coating designation AZ150.

-;1.4 <u>PERFORMANCE REQUIREMENTS</u>
-:#'''Wind Uplift Standards''': Engineered designs to resist wind uplift may refer to the British Columbia Building Code, Div. B, Appendix C, Table C-2 which lists various types of loads, including wind loads, for specific reference locations throughout the province. See also [http://{{SERVERNAME}}/index.php?title=ASM_Application_Guides_and_Notes Guides and Notes (Wind Resistance)] for a simplified calculation procedure. Regardless of the resources indicated here, the Design Authority is responsible to perform accurate wind load calculations and specify securement requirements.
