Products / Butlerib II Roof System

Butlerib II is a through-fastened metal roof panel system with a 1-1/2 in trapezoidal rib, with panels factory-punched to align with factory-punched purlins. Panels attach with Lock-Rivet or ScruBolt fasteners through slotted holes that allow thermal expansion and contraction, and are finished in Butler-Cote finishes. Butler lists UL Class 90, FM approval and Miami-Dade certification, and offers an optional 10-year weathertightness warranty.
