PRODUCT: DOUBLE-LOCK DL15 is a structural panel which is mechanically seamed during installation. The product is an integral interlocking system by design meaning the panels install in one direction from a given starting point. A DL15DM (double-male) starter panel is available (for a minimal set-up fee) and may be installed in the middle of a roof area to achieve a symmetrical layout. DOUBLE-LOCK utilizes the traditional SMACNA standing seam "double-lock" plate. Optional panel joint designs provide a wide range of overall building aesthetics. DOUBLE-LOCK is a very flexible panel design which works well with a wide range of building designs.
PRODUCT USES AND APPLICATIONS: Product uses include low to high slope roofing, vertical fascia, equipment screens, mansards, and wall panels. This system may also be installed on tapered and curved roof areas.
ROOF ASSEMBLIES: DOUBLE-LOCK DL15 can be applied over various roof assemblies including: open framing, rigid insulation (utilizing a bearing plate under each panel clip spaced 30" o.c., max.) over 22 ga. corrugated steel deck, and various solid substrates including plywood sheathing, nail base insulation, or steel deck.
Custom panel widths are available. Consult DMI for associated costs and lead times.
Continuous lengths from 4’-0” (min.) up to 90'-0" (max.) is standard. Lengths over 53’ require additional crating fees and special hauling permits. Contact DMI for details.
