R-Panel — Product Overview
The industry's most widely used exposed fastener panel — engineered for speed, coverage, and long-term structural performance in roof and wall applications.
R-Panel (PBR Panel) — Structural Overview
R-Panel is a through-fastened structural metal panel with 1¼" high ribs at 12" on center and 36" coverage width. It installs directly over purlins or a solid deck using exposed fasteners, making it one of the fastest and most cost-effective panel systems for commercial and agricultural use.
R-Panel performs equally well on both roof and wall applications, offering consistent structural performance, even-shadowed appearance, and broad compatibility with standard metal building systems across the U.S.

Galvalume® Panels
An aluminum-zinc alloy coating applied to the steel substrate, providing superior corrosion resistance and long service life. Galvalume is the industry standard for unpainted or light-colored metal roof and wall panels. Ideal for commercial, agricultural, and industrial applications where maximum durability and low maintenance are priorities.
