New call-to-action



Modern-Rib is McElroy Metal's newest panel. Modern-Rib combines the economics of an exposed fastener panel but with major ribs that simulate standing seam panels. Although an exposed fastener panel, Modern-Rib adds beauty and sophisticated styling to residential roofs and post frame structures.

Modern-Rib is available with Silicone Modified Polyester (SMP) and Kynar 500® (PVDF) coatings. For long-term performance and curb appeal, McElroy always recommends PVDF coatings.
