  1. General: Metal panels employ a hidden fastening system for securement to a solid substrate. 1" Super Snap-Loc design allows the panel seams to interlock without having to use a mechanical seaming device.
  2. Range of application: on wood or metal sloped roofs and to vertical wall framing in commercial, institutional, industrial and residential construction: also used for roof recovering or roof replacement (retrofit) application.
  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): To secure panel clips to steel, use No. 12-16 by 22 mm (1") long self-drilling, self-tapping, hex-washer head plated steel screws without sealing washers. Two fasteners per panel clip used, inserted into panel clip guide holes.
