SL25

PRODUCT: SPAN-LOCK SL25 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. SPAN-LOCK is a very flexible panel design which works well with a wide range of building designs. Four different clips are available: Low Floating, High Floating, Fixed, and Special Fixed for fixing panel at center point allowing for multi-directional expansion.

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 roof areas.

ROOF ASSEMBLIES: SPAN-LOCK SL25 can be applied over various roof assemblies including: open framing, rigid insulation (utilizing a bearing plate under each panel clip spaced 60" 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.
Factory Applied Non-Curing Sealant: for superior water tightness
Mechanically seamed: may be installed on low slope applications
No Hand Seaming Required: built-in locking leg keeps the roof panel in place until ready to mechanical seam
Multi-directional Mechanical Seaming: panel seaming is simplified
Expansion Clips: allows for thermal expansion and contraction
Continuous Rollformed Lengths: eliminates need for panel lap joints.

STANDARD PRODUCT OFFERING
24 ga., 22 ga. Steel, and .032, .040 Aluminum:

MODEL NO.		SEAM ON-CENTER
SL2516		16"

Custom panel widths are available. Consult DMI for associated costs and lead times.

NOTE: Continuous lengths from 4'-0" (min.) up to 95'-0" (max.) is standard. Panel lengths over 53'-0" require additional crating fees and special hauling permits. Contact DMI for details.

22 ga. Steel and .040 aluminum are 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 SPAN-LOCK (SL25) products are striated standard. See front for other optional stiffener patterns that are available.

Roof slopes under 3:12 require the use of hydro-static details. See DMI technical binder for more information.
