Product Group: STANDING SEAM METAL ROOF SYSTEM ZIMMERMAN SS 1500 STANDING SEAM PANEL

DESCRIPTION

The Zimmerman SS 1500 is an on-site continuous panel metal roofing machine. Panel profiles vary from 300 mm (12") to 500 mm (20") wide with a standing seam height of 38 mm (1½").

This on–site manufacturing eliminates the need for end laps, with continuous panel forming capabilities in lengths up to 15 – 24 m (50’).

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 employ a hidden fastening system for securement 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 for this panel: on wood or metal-sloped roofs; in commercial, institutional, industrial and residential construction; for reroofing or new construction.

.3 Panel Attachment:

Panel clips

One piece clip 64 mm (2½") wide by 38mm (1½") high with a 16 mm (5/8") base. The minimum thickness is 22 gauge metal; fastened to a plywood deck 600 mm (24") on centre. Custom-Built 2SS RC1.5" standing seam roof clip.

Fasteners

Used to attach clips to plywood to be #8 x 1" long pancake head, A-point, coated steel screw. Minimum 2 screws per clip. For steel decking or Z-girts, #8 x 1" long pancake head, having a self-drill and tap point, minimum 2 screws per clip.

.4 Plywood decking is to be nominal 13mm (½") thick or thicker.

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.
