Preweathered Zinc Gutters and Preweathered Zinc Downspouts have proven to be an ideal, durable material that has been used in gutter and roofing applications for centuries.
Similar to copper, preweathered zinc gutters and downspouts form a protective layer as it ages which is also known as patina. The patina, which develops as a result of exposure during weathering, gives zinc gutters its anti-corrosive characteristics that make this gutter a great long term investment.
