Corten Steel Planters
A Combination of Durability, Functionality & Modern Design
Durable. Architectural.
Designed to Weather Beautifully.
National Planter Supply manufactures Corten steel planters in Pennsylvania for residential, commercial, landscape, and architectural applications throughout the United States.
Made from weathering steel, Corten planters naturally develop a rich orange-brown patina that adds warmth, character, and architectural appeal to outdoor spaces. Available in standard and custom Corten steel planter designs, our products are built for durability and long-term outdoor use.
What Are Corten Steel Planters?
Corten steel planters are outdoor planting containers made from weathering steel that naturally develops a protective, rust-colored patina.
Unlike painted steel, Corten is designed to weather. Exposure to moisture and oxygen creates its distinctive earthy tones while giving each planter a unique appearance. The combination of durability, low-maintenance aesthetics, and architectural design makes Corten steel a popular choice for homeowners, landscape designers, architects, contractors, and businesses.
Residential Corten Steel Planters
Corten planters can turn ordinary planting areas into distinctive landscape features. Use them to define outdoor spaces, frame entrances, create focal points, or add structure to gardens and outdoor living areas.
Ideal applications include:
- Gardens and planting beds
- Patios and outdoor living spaces
- Pool and spa areas
- Outdoor kitchens
- Entryways and walkways
- Decks and terraces
- Privacy planting
- Decorative landscape features
Commercial & Architectural Corten Steel Planters
Corten steel planters are an excellent choice for commercial landscapes and architectural projects where durability and design are equally important.
Large planters can define pedestrian areas, separate outdoor spaces, soften architecture, and introduce natural elements into commercial environments.
Applications include:
- Restaurants and outdoor dining
- Hotels and hospitality properties
- Office buildings and corporate campuses
- Retail and multifamily developments
- Parks, plazas, and public spaces
- Courtyards and streetscapes
- Architectural and commercial landscape projects
National Planter Supply specializes in custom Corten steel fabrication for projects requiring specific dimensions, configurations, or designs.
We can develop custom planter solutions for:
- Residential landscapes
- Commercial developments
- Architectural projects

Weathering varies depending on climate, exposure, installation, and environmental conditions.
Designing with Corten Steel Planters
Corten's warm, earthy tones pair well with:
