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-inch major ribs, 12 inches on center, Multi-Rib's bold profile adds a distinct beauty to any home.
Multi-Rib roof panels with McElroy's MoistureLok, offer a great option to address condensation challenges. The design of our MoistureLok product traps moisture and then releases it back into the air as natural humidity once conditions go back below the dew point.
