Epic Steel’s Flushwall Panel delivers the concealed fastener aesthetic contractors want with serious performance specs — 24-gauge steel at 1.00 lb per square foot, ASTM A924 Grade D rating with 50,000 psi minimum yield strength. The Ultra Low Gloss PVDF finish comes with a 35-year warranty backed by Kynar 500/Hylar 5000 chemistry.
This panel targets wall and soffit applications exclusively — not for roofing. The flat profile and concealed fastener system create a modern, architectural appearance that sets it apart from traditional ribbed panels. Modern mountain and contemporary construction projects have made it a popular choice, with contractors valuing the minimal glare and clean aesthetic.
Technical Specifications and Performance
The Flushwall Panel offers three standard coverage widths — 12”, 16”, or 20” — with an 11 5/8” variant specifically for soffit applications. Every panel features a 1-inch seam height and requires a minimum 9-inch length.

| Weight | 1.00 lb per square foot | manufacturer |
| Coverage Width Options | 12”, 16”, or 20” (11 5/8” soffit) | manufacturer |
| Seam Height | 1 inch | manufacturer |
| Minimum Length | 9 inches | manufacturer |
| Material Grade | ASTM A924 Grade D (50,000 psi min. yield) | manufacturer |
| Wind Uplift Rating | UL 580 Class 90 | tested |
| Fastener Spacing | 12 to 24 inches | manufacturer |
The striated surface option reduces oil-canning — that wavy distortion that shows up in flat metal panels. Integrated stiffener V-joints add structural strength without compromising the clean appearance. Montana’s temperature swings make oil-canning a real concern, especially on large wall expanses that catch afternoon sun.
The panel meets UL 580 Wind Uplift Class 90 standards and complies with AISI gauge tolerance requirements. Additional certifications include ASTM A792 for Galvalume and ASTM A653 for galvanized substrates.
Installation Requirements
The concealed fastener system works over both open purlins and solid substrates. #10 or #14 Woodgrip screws handle wood substrates, while #12 Tek screws work for metal applications. Fastener spacing follows engineered tables, typically ranging from 12 to 24 inches.
Any exposed fasteners on trim pieces require proper sealing with washers. Cut panels must be wiped clean of metal particles immediately — leaving those particles on the surface voids the warranty and causes rust streaks.
The panel works with standard Epic Steel trim pieces including Wainscot, J-Metal, F+J, and both inside and outside corners. Despite its versatility in wall applications, it’s not compatible with sloped roofing — walls and soffits only.
Color and Finish Options
The Ultra Low Gloss PVDF finish uses Kynar 500/Hylar 5000 chemistry under Epic’s ULTRA-CLAD® system. Three specific ultra-low gloss colors target the modern aesthetic market: Carbon (Natural Matte), Iron Ore (Natural Matte), and Charcoal Gray.
The full color palette spans 39 options, from traditional agricultural colors like Hartford Green and Classic Green to contemporary choices like Burnished Slate and Cityscape. Specialty finishes include metallics (Copper Penny, Silver), textured options (Rawhide series), and weathered looks (Weathered Zinc, Western Rust).
The Verdict
Epic Steel’s Flushwall Panel earns its place in modern mountain construction through genuine performance advantages — the Ultra Low Gloss finish eliminates glare issues, the striated surface option fights oil-canning, and the concealed fastener system delivers the clean look contemporary projects demand. At 24 gauge versus 26 gauge alternatives, you’re getting 33% more steel weight (1.00 vs 0.75 lb/ft²) and superior wind uplift resistance.
The panel makes sense for commercial buildings, high-end residential projects, and agricultural structures where appearance matters. The 35-year PVDF warranty reflects real durability in Montana’s UV-intense environment. With UL 580 Class 90 wind ratings, it’ll handle the chinook winds that tear up lesser panels.
Not every project needs concealed fasteners or ultra-low gloss finishes. But for contractors building in Montana’s resort markets or commercial projects where aesthetics drive material choices, Epic Steel’s Flushwall Panel delivers measurable advantages over exposed-fastener alternatives.
Frequently Asked Questions
What makes Ultra Low Gloss different from standard finishes?
Ultra Low Gloss PVDF finishes reduce visible oil-canning and eliminate glare — critical for large wall expanses. The Natural Matte options in Carbon, Iron Ore, and Frost provide an architectural appearance that standard glossy metal panels can’t match. The finish particularly suits modern mountain architecture where reflective surfaces clash with natural settings.
Can this panel work for roofing applications?
No — Flushwall Panel is designed exclusively for wall and soffit applications. The panel specifications clearly state it’s not compatible with sloped roofing. For roofing needs, Epic Steel offers other panel profiles designed to handle water shedding and snow loads.
What’s the actual weight difference between 24 gauge and 26 gauge?
The 24-gauge Flushwall Panel weighs 1.00 lb per square foot versus 0.75 lb per square foot for 26-gauge alternatives — that’s 33% more steel. The extra weight translates to better wind resistance, reduced oil-canning, and improved impact resistance. On a 2,000 square foot wall, you’re adding 500 pounds of steel strength.
How does the concealed fastener system handle Montana’s freeze-thaw cycles?
The concealed fastener design allows for thermal movement while maintaining weather protection. Proper installation with correct fastener spacing (12 to 24 inches per engineered tables) ensures panels can expand and contract without buckling or pulling loose. The system eliminates the rubber washer deterioration issues common with exposed fastener panels.
