L-Shaped Raised Modular Corten Steel Planter Box | Open Bottom Corner Planter

Designed for flexibility, durability, and architectural impact, the L-Shaped Raised Modular Open-Bottom Corten Steel Planter Box is a premium solution for modern residential and professional landscape applications. Engineered to bolt together on-site, this modular open planter allows for precise configuration and fits neatly into corners, making it an ideal choice for patios, walkways, and outdoor living spaces.

Crafted from heavy-duty 10-gauge weathering Corten steel, the planter develops a rich, rust-like patina over time while forming a protective surface layer that resists corrosion without paint or sealant. The open-bottom design promotes natural drainage and healthy root growth, making it well-suited for trees, shrubs, ornamental grasses, and raised vegetable gardens.

Built for long-term outdoor use, this raised planter box offers exceptional structural strength while maintaining a clean, contemporary aesthetic that complements both modern and traditional landscapes. Its modular bolt-together construction makes installation efficient for landscape professionals and adaptable for homeowners seeking a fully custom garden layout.

Planters ship un-rusted in a raw steel finish. When exposed to outdoor elements, Corten steel will naturally develop its signature protective rust patina over several weeks to months. The final color and texture will vary based on your local climate and exposure, resulting in a completely unique finish over time.
