Berea, OH exposure site. Open backed metal racks on asphalt slab.  Open backed panels will be used unless otherwise specified.   Panels typically exposed at 45° South.

 

Additional asphalt area available for horizontal panel exposure (deck stains).  If necessary horizontal coatings can be exposed on pallets.  Panels will be evaluated typically at 6 months, 1 year, and 2 years unless otherwise specified.  A report will detail substrate type and a client can contact CRGI for any further details on the substrate used.  CRGI washes panels using dish soap and water. 

 

CRGI subcontracts panels to Q-Panel for exposure (Homestead ,Florida, and Buckeye, Arizona) if needed.
