Multi-Rib Panel

Multi-Rib is McElroy’s proprietary version of the industry’s standard R-Panel and is a multi-use roof and wall rib panel primarily used in pre-engineered metal building applications. An optional purlin bearing leg (PBR) rests on purlins and provides support for fastening the panel lap.

Multi-Rib is also commonly utilized for residential roofing, primarily in the Southwestern region. Featuring 1 1/4″ major ribs, 12 inches on center, Multi-Rib’s bold profile adds a distinct beauty to any home.
