Epic Steel’s Flushwall Panel combines concealed fastener aesthetics with DIY-friendly installation and high-strength 80 ksi steel construction. This 24-gauge panel delivers the clean look contractors want without the installation complexity of mechanical lock systems.
The concealed fastener system creates a minimal appearance while maintaining economical and DIY-friendly installation. That’s the real achievement here. Most concealed fastener panels require specialized installers. Flushwall doesn’t.
Installation Flexibility and Specifications
The fastener system adapts to whatever substrate you’re working with. On dimensional lumber, use #10 Wood-Grip screws. For plywood or OSB, step up to #14 Wood-Grip screws. Structural steel calls for #12 Tek screws. Fasten every 12-24 inches depending on substrate and wind load requirements.
Can be installed over solid substrates or open purlin systems with a maximum free span of 24 inches. That versatility matters when retrofitting existing buildings or working with different framing systems.
Width options give contractors real flexibility:
| Panel Type | Width Options | Seam Height |
|---|---|---|
| Standard Soffit | 11 5/8” | 1/2” |
| Wall Panel | 12”, 16”, 20” | 1” |
Reveal options go up to 3 inches in 1/2 inch increments. That’s architectural control without custom fabrication. Typical 2-3 day lead time for standard profiles beats the weeks-long waits for custom mechanical lock systems.
Material Strength That Matters
Grade E steel with 80 ksi yield strength puts this panel in a different class than standard siding. Most residential panels use 33-50 ksi steel. The extra strength shows up in wind resistance and long-term performance.
| Specification | Value |
|---|---|
| Material | Galvanized Steel, Grade E (80 ksi yield) or Grade D (>= 50 ksi yield) |
| Gauge | 24 |
| Weight | 1.00 lb per sq ft |
The testing backs up the strength claims. ASTM E1592 wind uplift resistance, UL 90 uplift rating, ASTM E283 air infiltration testing, and ASTM E331 water penetration testing cover the performance bases contractors care about.
40-year limited structural warranty reflects manufacturer confidence. Paint finish warranties reach 35 years on ULTRA-CLAD (Kynar/PVDF) systems. Those aren’t marketing numbers. They’re based on accelerated weathering tests that simulate decades of UV exposure.
Installation demands attention to detail. Store panels dry and elevated to prevent moisture-induced corrosion (white rust). Always cut panels facing down to prevent hot shavings from damaging the finish. Remove all metal shavings immediately after cuts to maintain warranty. Basic stuff, but skip these steps and callbacks follow.
Surface finish options include smooth or perforated. The perforated option handles acoustics or ventilation control in soffit applications. Stock colors run from Acrylic Coated Galvalume through specialty finishes like Gun Metal (Low-Gloss Textured) and Coal Black Rawhide (Textured).
FAQ
What makes Flushwall different from standard metal siding panels?
The concealed fastener system creates a clean, minimal appearance without visible screw heads. Unlike mechanical lock systems that require specialized installation, Flushwall maintains economical and DIY-friendly installation while delivering architectural aesthetics.
Can this panel handle Montana’s wind loads?
Grade E steel with 80 ksi yield strength exceeds standard siding materials. Testing includes ASTM E1592 wind uplift resistance and UL 90 uplift rating. Fastener spacing adjusts from 12-24 inches based on wind load requirements.
What width options work best for different applications?
Standard soffit width is 11 5/8 inches with 1/2 inch seam height. Wall panels come in 12, 16, and 20 inch widths with 1 inch seam height. The narrower widths create tighter shadow lines. Wider panels cover more area per pass.
How fast can I get these panels compared to custom orders?
Typical 2-3 day lead time for standard profiles. That’s significantly faster than mechanical lock systems that often require weeks for custom fabrication.
What substrates work with this panel system?
Can be installed over solid substrates or open purlin systems. Use #10 Wood-Grip screws for dimensional lumber, #14 Wood-Grip screws for plywood or OSB, and #12 Tek screws for structural steel. Maximum free span is 24 inches.
