PBR

UL 2218 Class 4

PBR is Union Corrugating's structural, exposed-fastener panel ("Purlin Bearing Leg Panel") for metal roofing, with a minimum recommended roof pitch of 1:12, a 36-inch coverage width and a 1-1/4-inch rib height, suitable over solid decking or open framing. The company's own PBR Guide Specification states the panel meets U.L. Class 4 hail resistance and Class A fire resistance tested to U.L. 263, and is rollformed from 24-gauge Galvalume steel at 36-inch panel width in that specification's base product description. The product page states Miami-Dade County approval and lists Galvalume Plus, Signature 200 and (26-gauge) additional coating options.
