R-Panel Top 3 Benefits

  1. High Structural Strength: With 1¼" high ribs and wide 36" coverage, R-Panel provides superior spanning capability and load resistance across large roof and wall systems.

  3. Proven Performance and Long-Term Durability: Available in Galvalume®, Kynar 500® (PVDF) finishes for superior fade, chalk, and corrosion resistance and Silicone Modified Polyester (SMP) finishes for budget-conscious projects with lower performance expectations.
