Meet UL Specifications:
Uplift Resistance (UL 580)
Impact Resistance (UL2218)
Fire Exposure (UL 790)
Uplift Resistance: Standard UL 580 provides testing in regards to the amount of uplift
resistance a roof decking panel can withstand while it is properly attached to a roofing structure. Roof decking that passes the testing criteria will be listed as either “Class 15”, “Class 30”, “Class 60” or “Class 90”. A “Class 15” rating represents nominal, static uplift-pressure resistance of 15 lbs per square foot while a “Class 90” rating represents nominal, uplift-pressure resistance of 90 lbs per square foot. The classified metal roof deck panels manufactured (roll formed) by Graber Post Buildings, Inc. are all classified as “Class 90”.
Impact Resistance: Standard UL 2218 provides testing in regards to impact resistance by performing tests that simulate impact similar to impact a roof decking panel might experience during the course of a hail storm or other impact. All metal roof decking material that is classified as to impact resistance will be rated as “Class 1 “, “Class 2”, “Class 3” or “Class 4”. This test involves dropping steel balls of various weights from different heights. These balls are also dropped in areas that might be considered the most vulnerable to impact damage such as corners and edges. In order to obtain a “Class 1” rating a material must be able to show damage resistance to one and one-quarter inch steel ball dropped from twelve feet. A “Class 4” classification can be attained if the material shows resistance to a two inch ball dropped from twenty feet. The classified metal roof deck panels manufactured (roll formed) by Graber Post Buildings, Inc. are all classified as “Class 4”.
External Fire Exposure: Standard UL 790 provides testing in regards to the ability of roof decking to withstand external fire. In order to be classified material must show resistance to fire, resistance to slipping, and resistance to producing fire ambers. The classified metal roof deck panels manufactured (roll formed) by Graber Post Buildings, Inc. are all classified as to external fire exposure.
