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.NOTE:Continuous lengths up to 90'-0" is standard. Lengths over 53'require additional crating fees and special hauling permits. Contact DMI for details.22 ga. steel, and .032 aluminum are not stocked in all colors.

See front for other optional stiffener patterns.Double Male panels are not recommended with metallic finishes due to the paint finish being directional and may cause color variation or shading.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.
