Product Group: STANDING SEAM METAL ROOF SYSTEM – ESE 100 STANDING SEAM PANEL

DESCRIPTION

The ESE 100 Standing Seam Metal roof is shop formed and on site continuous panel metal roofing machine. Panel profiles vary from 330 mm (13") to 533 mm (21") wide with a seam height of 25 mm (1"). Standard width is 13", 15" or 21". It can be formed with optional stiffening ribs or striation to reduce oil canning. The panel can also be formed into curved and tapered panels. Batterns can be attached to the 1" seam height for a more distinct architectural look.

1.1 GENERAL

The roofing assembly / material information published in the RCABC Roofing Practices Manual DOES NOT represent a complete set of the manufacturer's published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.

1.2 SYSTEM DESCRIPTION

.1 Standing seam panels use a hidden fastening system for securement to a solid substrate. The panels are seamed together with a mechanical seamer.

.2 The range of application for this panel: on wood or metal sloped roofs; in residential, commercial, institutional and industrial applications; for reproofing or new construction.

.3 Panel Attachment:

Fasteners (Screws)

For panel clip to steel attachment to be No. 13-16 by 22 mm (1") long self-drilling, self-tapping, hex-washer head plated steel screws used without sealing washers. Two fasteners per panel clip used, inserted into panel clip guide holes.

Roof Deck Fasteners (Panel Clip)

There are two types. One piece 1.5" wide by 1" high with a 1" base in 24 ga as manufactured by Lam Metal. Two parts assembly consisting of a a24 ga msg minimum thick coated steel base approximately 1" wide x 5" long and 24 ga msg minimum thick steel upper tap section height 1" as manufactured by Logan Stamping Ltd.

1.3 SITE CONDITIONS

.1 Minimum roof slope is 1:6 (2" in 12"). Severe conditions (heavy snow or ice) minimum slope is 1:1.5 (8" in 12").

1.4 PERFORMANCE REQUIREMENTS

.1 Wind Uplift Standards:

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.
