Planter Material & Finish Options:

  • Aluminum - The aluminum used for these planters is made from high quality marine grade aluminum. This aluminum alloy is light weight, exceptionally strong, and guarantees a long lasting, rust and maintenance free product. This material is the perfect solution for highly corrosive environments, or for placement on porous or easily stained surfaces. Available in 8 standard powder coat finishes as well as the oxidized zinc patina finish. 

  • Corten Steel- The Corten (weathering steel) planters are constructed from a thick 14 gauge 606 alloy. This alloy is a common architectural elements because corten steel has a protective weathering quality that makes it extremely durable. These corten planters are available only in a natural rust patina finish, and will continue to rust and change. 

  • Mild Steel- Mild steel planters are made from a thick hot rolled low carbon steel. This type of steel offers a very durable yet more cost effective solution and has a nice rustic appearance. Mild steel is only available only in a natural rust finish and will continue to rust.        

Note: Natural rust patina products will transfer color to light colored or porous surfaces. They are not recommended in areas where surface staining is a concern.
