The 1" Snap-Loc is a metal roof panel formed from 24 gauge. The panel can be applied on to solid sheeting with or without insulation. Width from 300 mm (12") to 400 mm (16") wide with a 22 mm (1") height at the male rib. Panels are continuous with no end laps.

SYSTEM DESCRIPTION

1. General: Metal panels employ a hidden fastening system for securement to a solid substrate. 1" 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; in commercial, institutional, industrial and residential construction; for re-roofing or new construction.
3. Fasteners (Screws): Fasteners (screws) used to attach panels to plywood deck to be No. 8 by 22 mm (1") panhead. Fasteners to be placed a maximum of 600 mm (24") on center.
4. Fabrication: Unless otherwise shown on drawings or specified herein, fabricate panels in continuous one piece lengths and fabricate flashings and accessories in longest practical lengths.
5. Deck Requirements: in keeping with the Standard for Architectural Sheet Metal (ASM) Systems.

DELIVERY, STORAGE & HANDLING

1. Protect against damage and discoloration.
2. Handle panels with non-marring slings.
