Why Buy Copper?

 

 

 

 

For nearly 5,000 years, copper was the only metal known to man. Today it is one of the most used and re-used metals, and it is our clear choice as an exceptional material for artistic, high-quality outdoor lighting fixtures.

The range of copper's natural colors make an attractive appearance during various stages of weathering. In industrial and seascoast atmospheres, the patina takes five to seven years and in rural areas, ten to fourteen years. In our landscape lighting fixtures, weathering allows the lights to gradually blend into their surroundings, an effect that is especially attractive with our many designs inspired by plants and flowers.

Natural corrosion resistance permits its use in a wide array of environments. During the early stage of weathering, copper oxide conversion films are formed on the exposed copper. As weathering continues, cuprous and cupric sulfide films are interspersed with the initial oxide films. These sulfide conversion films range from bown to black. As they build, the exposed surface darkens appreciably. Continued exposure results in the conversion of the sulfide films to the basic copper sulfate patina. This familiar greenish patina acts as a protective film that inhibits further corrosion.

Unlike plastics and other materials, copper is unaffected by sunlight and will not embrittle with age, so it can’t crack or crumble after years of installation. Copper light fixtures are among the most beautiful and durable for landscaping and nightscaping applications.
