COR-TEN Weathering Steel Planters: Options & Key Features

Naturally Weather-Resistant: Observe how COR-TEN Weathering Steel forms a protective patina over time, creating a unique rust-like appearance that shields the planter from moisture and harsh elements. This natural oxidation process enhances both the durability and visual appeal of your outdoor space.

Patina Process: Your COR-TEN Weathering Steel Planter will arrive in a raw steel state and develop its characteristic bronze patina when exposed to the outdoors. For faster results, pre-treatment options are available upon request to jumpstart the patina, but final oxidation will occur outdoors.

Surface Staining: COR-TEN Weathering Steel Planters may cause surface staining due to runoff after heavy rain or watering. It's important to design your project with this in mind.

Application Possibilities: These planters are perfect for a variety of outdoor settings, including urban rooftops, shopping centers, condos, medical facilities, industrial parks, retail complexes, warehouses, senior living facilities, trucking and distribution centers, schools, colleges and universities, business campuses, government buildings, parks, and more.

I worked with Eric Gustafson on a project with an extremely tight deadline. He promised me delivery by the 7th. He delivered on the 6th. This hardly ever happens in our industry. My client could not have been more pleased. He was also a pleasure to work with. Product was exactly as expected. I will certainly work with Pure Modern again and strongly recommend them.”

Frequently Asked Questions: COR-TEN Weathering Steel Planters

  • Any mention of patina refers to our products made of COR-TEN Weathering Steel. Patina is an important process for COR-TEN Weathering Steel, which gets its name from its corrosion resistance (COR) and tensile strength (TEN).

    For COR-TEN Weathering Steel to become fully corrosion-resistant, it undergoes a patina process. The steel changes from a raw metal look (in which the color of the steel is gray) to a patina (where the metal turns orange-brown).

    To patina, the planter needs to be in the elements. COR-TEN Weathering Steel planters should only be outdoors and uncovered. It is important to note that when the planter goes through the patina process, the metal can bleed onto the surrounding surface.

    After this transition, the weathering process of COR-TEN Weathering Steel is complete. The steel is now resistant to corrosion and perfect for many outdoor climates. Note: COR-TEN Weathering Steel Planters must be at least two kilometers away from large bodies of saltwater, as saltwater can erode this material.

    If you love the look of COR-TEN Weathering Steel but do not think the material will work for your needs, we recommend using Powder-Coated Aluminum Planters in Weathered Rust finish. Aluminum Planters are a commercial alternative that mimics the look of COR-TEN Weathering Steel.
