CR-DL15

PRODUCT: CURVED-RADIUS DOUBLE-LOCK CR-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 CR-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. CURVED-RADIUS DOUBLE-LOCK utilizes the traditional SMACNA standing seam "double-lock" plate. CURVED-RADIUS 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 barrel roofing, equipment screens, and mansards.

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.

ADVANTAGES:

UL-90 classified assemblies: high wind uplift loading capacities
ASTM Air, Water Infiltration and Structural Tested: proven air and water tightness
Factory Applied Non-Curing Sealant: superior watertightness
SMACNA Seam Design: a traditional and historical aesthetic appearance
Mechanically Seamed: may be installed on low slope applications
Expansion Clips: allows for thermal expansion and contraction
Continuous Rollformed Lengths: eliminates need for panel lap joints.

NOTE: Continuous lengths from 3’-0” (min.) up to 90'-0" (max.) is standard. Lengths over 53’ require additional crating fees and special hauling permits. Contact DMI for details.

22 ga. steel cannot be double-locked and is not stocked in all colors. Minimum order quantities and extended lead times may accompany panel orders when utilizing these substrates

Oil-canning, the slight waviness inherent with light gauge metal, does not affect the finish or structural integrity of the panel and is therefore not cause for rejection.

All DOUBLE-LOCK products are smooth standard.

Double Male panels are not recommended with metallic finishes due to the paint finish being directional and may cause color variation or shading.
