The powder coated aluminum garden planters are made from marine grade .090” thick 5052 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.

Cor-Ten Steel

Cor-Ten, or weathering steel, planters are made from .074” thick 606 alloy Cor-Ten steel. Common in architectural elements, this steel alloy is used for its unique rustic appearance and protective weathering qualities. This ultra durable material is perfect for all indoor or outdoor environments, as well as for commercial projects. Cor-ten products are available only in a natural rust patina finish, and will continue to patina and change over time.

Mild Steel

Mild steel garden planters are made from .074” thick hot rolled low carbon mild steel. Mild steel offers a very durable yet cost effective solution, is valued for its unique rustic appearance, and will continue to patina and change over time. Mild steel products are available only in a natural rust patina finish.        

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.

The metal garden planters come standard with 1”drain holes. They are designed to be directly planted into, and do not require grow pots or liners. Please let us know at the time of order if you do not want drain holes or need custom drainage options.
