A Class 4 rating is the highest tested rating for impact resistance under the UL 2218 standard for metal roofing panels. This certification indicates the roof material has passed testing that simulates withstanding 2” diameter hail with no visible defect. Our 26 gauge panels (and thicker) pass this testing.

PBU panels offer the same look and coverage as U Panel, but includes an extra "leg" on one side of the sheet. The PB stands for purlin bearing, and is designed to go against the purlin or substrate with the lapping rib going over the top. This aids in installation in holding the sheet stable as screws are applied. Note: the side with the extra rib must go under the lapping side.
