The Fabral UltraLoc 16 delivers standing seam aesthetics without the hand-seaming hassle. This 26-gauge Galvalume panel combines a concealed fastener system with Class 4 impact resistance — performance specs that competing panels rarely match. At 16 inches of coverage per panel with a 1-inch seam height, it targets residential contractors who need professional appearance without the labor complexity of traditional standing seam.
The system works for residential roofing, agricultural buildings, light commercial projects, and retrofitting over existing asphalt roofs. Montana contractors appreciate the UL 790 Class A fire resistance rating and UL 2218 Class 4 hail impact resistance — certifications that matter when you’re building in wildfire zones with regular hail events.
Installation System Cuts Labor Time
The concealed fastener system uses clips with 2 fasteners each, spaced at 16 inches on center for gable cleats. No hand seaming required. That’s the key differentiator from traditional standing seam systems that eat up crew hours crimping panels together. Panels run up to 40 feet maximum length (subject to regional and transportation limits), which means fewer horizontal seams on long rural buildings.
The system installs on solid decking — plywood or OSB substrate required. But here’s where it gets interesting for retrofit jobs: UltraLoc installs directly over existing asphalt roofs. Skip the tear-off costs and disposal fees. The lightweight 26-gauge steel makes handling easier for smaller crews working steeper slopes.
Installation requires standard trim components: concealed clips, ridge caps, gable and rake trim, eave trim with drip edge, sealants, and closure strips. Nothing proprietary or hard to source. Compatible with synthetic or felt underlayment and standard Fabral residential trim and flashing profiles.
Performance Ratings Beat Exposed Fastener Systems
The 26-gauge high-strength steel features Galvalume AZ50 aluminum-zinc alloy coating — the industry standard for corrosion resistance. Minimum slope requirement sits at 3:12, steeper than the 1:12 you’d get away with on exposed fastener panels. But that’s the trade-off for concealed fastener water-tightness.
| Specification | UltraLoc 16 | Source |
|---|---|---|
| Material | 26 GA Galvalume (AZ50) | manufacturer |
| Panel Coverage | 16 inches | manufacturer |
| Seam Height | 1 inch | manufacturer |
| Fire Resistance | UL 790 Class A | tested |
| Impact Resistance | UL 2218 Class 4 | tested |
| Minimum Slope | 3:12 | manufacturer |
Stiffening ribs enhance strength and rigidity — critical for handling Montana snow loads without oil-canning. The paint options include Enduracote or WeatherXL SMP high-performance systems, with Energy Star approved standard colors available.
Customer feedback highlights the high strength-to-weight ratio and aesthetic appeal of the concealed fastener system, with users noting it’s easier to install than traditional standing seam systems. That matters when your crew needs to close in a house before October frost.
Warranty Coverage
Fabral backs the UltraLoc with a Limited Lifetime Warranty on film integrity, 30 years on chalk and fade resistance, and 20 years against perforation for the Galvalume coating. Standard coverage for this gauge and coating combination. The perforation warranty matters more than paint warranties in Montana — UV damage happens everywhere, but moisture infiltration kills roofs.
How does UltraLoc stack up? The Horizon 16 serves as the Western Region equivalent with virtually identical specs. Against 1-1/2 inch SSR panels, you’re looking at a higher 1.5-inch seam that often comes in 24-gauge steel. Compared to exposed fastener panels, UltraLoc provides superior aesthetics and leak protection.
Bottom Line for Montana Contractors
UltraLoc 16 fills the gap between agricultural panels and full standing seam systems. The concealed fastener design eliminates the rubber washer maintenance of exposed fastener panels while avoiding the field-seaming labor of architectural standing seam. Class 4 impact resistance handles Montana hail. The 3:12 minimum slope works for most residential and agricultural applications.
At 40-foot maximum lengths, you’ll minimize end laps on pole barns and equipment sheds. The retrofit capability over existing shingles saves tear-off costs and keeps projects moving when dump fees and disposal logistics threaten timelines.
Not the cheapest metal roofing option. Not the most premium either. But for contractors who need concealed fastener performance without standing seam installation complexity, UltraLoc 16 delivers exactly what it promises.
Frequently Asked Questions
Q: What gauge is the Fabral UltraLoc 16 panel and what’s the maximum panel length available?
The Fabral UltraLoc 16 comes in 26-gauge high-strength steel with Galvalume AZ50 aluminum-zinc alloy coating. Panels are available up to 40 feet in length, though actual maximum lengths depend on regional availability and transportation limitations.
Q: What’s the minimum roof slope for UltraLoc 16 installation?
Fabral UltraLoc 16 requires a minimum slope of 3:12, which is steeper than exposed fastener panels that can go down to 1:12. This 3:12 minimum ensures proper water drainage with the concealed fastener system.
Q: Can I install UltraLoc 16 directly over existing shingles?
Yes, Fabral UltraLoc 16 can be installed directly over existing asphalt roofing, eliminating tear-off costs and disposal fees. The lightweight 26-gauge panels require solid decking underneath (plywood or OSB), whether installing over existing roofing or on new construction.
Q: What fire and impact ratings does the UltraLoc 16 carry?
Fabral UltraLoc 16 holds UL 790 Class A fire resistance rating and UL 2218 Class 4 impact resistance certification. These are the highest ratings available for fire and hail impact protection in metal roofing systems.
Q: What warranty coverage comes with Fabral UltraLoc panels?
Fabral provides a Limited Lifetime Warranty on film integrity, 30 years coverage against chalk and fade, and 20 years against perforation for the Galvalume coating. The perforation warranty specifically covers the AZ50 aluminum-zinc coating system.
Q: What’s included with UltraLoc panels and what do I need to order separately?
Fabral UltraLoc 16 panels are sold individually without accessories. You’ll need to separately order concealed clips, ridge caps, gable/rake trim, eave trim with drip edge, sealants, and closure strips to complete the installation.
