Product Group: STANDING SEAM METAL ROOF SYSTEM – KNUDSON P-2406
- DESCRIPTION
The Knudson P-2406 is an on-site continuous metal roll forming machine. Panel profiles vary from 300 mm (12") to 500 mm (20") wide with a seam height of 38 mm (1.5"). Panels are produced with two stiffening flutes.
On-site roll forming provides for the elimination of end laps with continuous panel forming capabilities.
- 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 Architectural standing seam panels employ a hidden fastening system for securing to a solid substrate. Panels are seamed together with a mechanical seamer.
- .2 Range of application: on wood or metal sloped roofs; in commercial, institutional, industrial and residential construction; for reroofing or new construction.
- .3 Panel Attachment: Wood
- Panel clip to be Knudson 22 ga one piece assembly 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 600 mm (24") on centre. Two fasteners per panel clip used, inserted into panel clip guide holes. Fasteners to be #10 x 22 mm (1") long pancake head type A plated.
- Two piece assembly to be used for longer panel lengths, clip to be Knudson 22 ga 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 600 mm (24") on centre.
- Panel Attachment: Steel
- Panel clip to be Knudson 22 ga one piece assembly 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 600 mm (24") on centre. Two fasteners per panel clip used, inserted into panel clip guide holes. Fasteners to be #8-16 x 22 mm (1") long self-drilling, self tapping wafer head, plated screws.
- Two piece assembly to be used for longer panel lengths, clip to be Knudson 22 ga 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 600 mm (24") on centre.
- 1.3 SITE CONDITIONS
- .1 Minimum roof slope is 1:6 (2" 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.
- RGC accepted metal panel systems shall be formed of steel conforming to one of the following material specifications, as applicable:
