Medallion I and II Standing Seam Roof Panel
Classic snap-on batten seam systems designed for high-end architectural roofing applications.
McElroy Metal’s Medallion I and II use a separate batten cap installed over adjoining panels to create clean, traditional lines. Medallion I features a narrower cap for refined detailing, while Medallion II offers a wider profile for bold architectural expression.
