zinc

Zinc is a light, brittle metal which is sometimes used in facades for its silvery appearance and resistance to corrosion. Its color is light gray, often with a silvery luster, and with a slight bluish tint.

The zinc forms the facade surface. Its pale gray or bluish metallic appearance is distinct from a paint color on another material.

Surface treatment and exposure can affect its appearance. The material remains zinc even when its initial metallic luster becomes less pronounced.
