OVERVIEW

The New Tech SSH 2070216 is an on-site continuous panel metal roofing machine. Panel profiles vary from 300 mm (12") to 508 mm (20") wide; stiffening ribs are standard.

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

1. General: The MK Mechanical Lock is a mechanically locking, concealed fastener roofing panel, secured with independent standing clips. The panel can be formed in any width between 300 mm (12") to 508 mm (20"). The male leg locks along the entire length of the panel and does not rely upon clips to provide additional locking.
2. Range of application: on wood or metal sloped roofs; in commercial, institutional, industrial and residential construction; for re-roofing or new construction.
3. Fabrication:
   1. Unless otherwise shown on drawings or specified herein, fabricate panels in continuous one piece lengths and fabricate flashings and accessories in longest practical lengths.
   2. Roofing panels shall be factory formed or site formed.
   3. Verify prior to fabrication.
   4. If field measurements differ from drawing dimensions, notify Architect / Professional Engineer prior to fabrication.
4. Fasteners (Screws): Fasteners used to attach panel clips to steel to be No. 10 - 16 pancake head, No. 2 Phillips drive, No. 3 self-drilling point steel screws.
