Preweathered Zinc Downspouts are available in 3" or 4" plain round. Zinc Downspouts form a protective layer over time. Like copper patina, this forms due to weathering and the anti-corrosive properties protect zinc downspouts from deterioration.
Zinc Downspouts pair best with zinc gutter systems for a uniform look. It's best to install everything at once so that the system ages all at the same pace. Preweathered Zinc Downspouts are available in plain round style.
