At National Planter Supply, we design garden systems that look great, last long, and work hard for the environment. Our modular Corten steel garden beds are a standout example of that philosophy in action.
Built from a clever system of four universal corners and interchangeable length panels, these beds are engineered to assemble easily and adapt to any layout. Whether you’re building a compact kitchen garden or a long, linear feature, the modular design lets you create exactly what you need—with support bars added where needed to ensure long-term structural strength.
But these beds offer more than flexibility—they’re built to last using Corten steel, a material that’s as eco-conscious as it is elegant.
Endless Possibilities for Outdoor Spaces
Whether you’re planning a private backyard or designing a public green space, modular Corten beds offer the flexibility to fit your vision. Here are just a few ways our clients are using them:
- Vegetable Gardens: Raised beds make food production easier on the back, and the heat-retaining quality of Corten steel can help warm soil faster in spring.
- Herb & Kitchen Gardens: Compact configurations are perfect for culinary herbs placed near patios or outdoor kitchens.
- Ornamental Plant Displays: The rich patina of weathered steel pairs beautifully with grasses, perennials, and structural plantings.
- Terracing on Slopes: Modular beds can be installed in a tiered layout to control erosion and turn hillsides into productive or decorative planting areas.
- Urban & Rooftop Gardens: Lightweight relative to poured concrete, these modular beds are ideal for rooftop applications with proper load-bearing structures.
- Commercial & Institutional Use: They make a bold statement in office courtyards, school gardens, restaurants, and multi-family developments—where durability and clean design matter.
- Public Art or Architectural Features: With their geometric flexibility, modular Corten beds can also function as sculptural elements in minimalist or modern designs.
Built for Beauty and Built to Last
What truly sets these garden beds apart is the use of Corten steel, a weathering material that forms a stable, protective patina over time. This eliminates the need for paint or toxic coatings and gives each bed a warm, earthy tone that evolves naturally.
Sustainability Highlights:
- 100% recyclable material
- No chemical treatments needed
- Extremely long service life
- Often locally sourced to reduce emissions during transport
Unlike treated lumber or composite materials that can degrade or look dated, Corten continues to perform and patina for decades.
