Product Group: STANDING SEAM METAL ROOF SYSTEM – MR/S-150

DESCRIPTION

The New Tech Machinery Panel Machine is an on-site continuous panel metal roofing machine. This machine produces MR/S-150 panels with a seam height of 38 mm (1-1/2"). Panel profiles vary from 300 mm (12") to 500mm (20") wide.

On-site roll forming provides for the elimination of end laps with continuous panel forming capabilities in lengths up to nominal 46 m (150').

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 clip system for mechanical fastening to a solid substrate. The maximum spacing of the clips is 600 mm (24") on centre. The panels are locked together with the clips as part of the seam, by use of a mechanical seamer.

.2 Range of application: on wood or metal sloped roofs with or without exterior insulation; in commercial, institutional, industrial and residential construction; for reroofing or new construction.

.3 Panel Attachment:

Fasteners (Screws)

Fasteners used to attach panel clips to steel to be No. 10-16 by 25 mm (1") long pancake head, No. 2 Phillips drive, A-point, coated screw. Minimum two fasteners per clip to be used.

Roof Deck Fasteners (Panel Clips)

One piece assembly 43.75 mm (1-3/4") wide, 31 mm (1-1/4") high. Minimum thickness 0.022". (No. 22 MSG). Clips spaced 600 mm (24") on centre fastened to plywood deck. Englert "series 1000 Interlocking Clip".

1.3 SITE CONDITIONS

.1 Minimum roof slope is 1:4 (3" 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.
