Preweathered Zinc Gutters

For projects that require the look of a ”finished” Preweathered Zinc Gutters - surface patina upon completion of installation, Preweathered Zinc Gutter material has developed a technique known as ”preweathering”. This process, which is unique worldwide, allows for controlled development of the surface. As there isn’t any coating involved in the ”preweathering” process, the elemental properties of zinc aren’t influenced in any way. Natural weathering sets in and the protective patina is formed, just as it would if the material were bright-rolled.
