Pre-Patina Copper (Evergreen).
This revolutionary product is solid copper-
99.5% pure, with real patina on one side that
would normally take around 25 years or more to
form. It is made possible through a
manufacturing process, which duplicates and
accelerates copper's natural aging
for gutters, metal roofing panels,
downspouts, chimney caps,
cupolas, louvers, finials, edge metal, flashing,
step flashing, leader heads, gutter accessories, conductor boxes & skylights.
