OVERVIEW
The New Tech Machinery Panel Machine is an on-site continuous panel metal roofing machine. Panel profiles vary from 300 mm (12") to 457 mm (18") wide with a 44 mm (1-3/4") rib.
On-site roll forming provides for the elimination of end laps with continuous panel forming capabilities in lengths up to nominal 46 m (150').
SYSTEM DESCRIPTION
- General: The MR-675 44 mm (1-3/4") is a snap lock concealed fastener roofing panel. The panel can be formed in any width between 300 mm (12") to 457 mm (18"). Stiffening ribs, striations and/or clip relief can be added depending on the application. The male leg locks along the entire length of the panel and does not rely upon clips to provide additional locking. The MR-675 utilizes 153 mm (6-1/8")of metal in forming the panel legs providing greater structural integrity, which can carry greater load.
- Range of application: on wood or metal sloped roofs with or without exterior insulation; in commercial, institutional, industrial and residential construction; for re-roofing or new construction.
- Fasteners (Screws): Fasteners used to attach panel clips to steel to be No. 10 - 16 by 25 mm (1") long cadmium plated pancake head, No. 2 Phillips drive, No. 3 self-drilling point steel screws. Two screws per clip inserted through 6.25 mm (1/4") diameter guide holes.
- Panel Clips: One piece assembly, No. 22 MSG min. thick, 88 mm (3-1/2") high. One panel clip spaced at 600 mm (24") on centre for Class 90.
- Deck Requirements: in keeping with the Standard for Architectural Sheet Metal (ASM) Systems.

PERFORMANCE REQUIREMENTS
- 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 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.
- Materials:RoofStar (RGC) accepted metal panel systems shall be formed of steel conforming to the standards published in the Standard for Architectural Sheet Metal (ASM) Systems.
