22" CorTen Steel Modular Raised Garden Bed - Weathering Steel
Build the perfect raised garden bed for your space with ultimate flexibility. Straightcurve's 22" Modular Planter system features premium CorTen weathering steel panels that connect in endless configurations, delivering professional-grade depth for deep-rooted vegetables, dramatic planters, and multi-level landscape features.
Why Choose 22" Modular Planters?
- Extra Depth for Serious Growing: 22" height accommodates deep-rooted crops like tomatoes, carrots, and root vegetables
- Unlimited Configurations: Mix and match 6 different panel lengths to create custom shapes and sizes
- Living Finish: CorTen steel develops a beautiful rust patina that protects against corrosion while adding warmth
- Safe Design: Folded lip eliminates sharp edges for safer installation and maintenance
- Professional Quality: 2mm thick weathering steel with 1.8" top lip by Straightcurve
Note: Weathering steel panels arrive in their natural pre-weathered state (black/gray) and will develop their signature rust patina once exposed to the elements. Rusting time varies by climate.

Frequently Asked Questions
Q: What's included with each panel?
A: Each panel is sold individually. Connectors, corners, and bracing are sold separately so you can customize your exact configuration.
Q: How do I calculate how many panels I need?
A: Measure your desired planter dimensions. For a simple rectangular bed, you'll need 2 panels for length + 2 panels for width, plus 4 closed corners and straight joiners if stacking height.
Q: How long does the rust patina take to develop?
A: Typically 3-6 months depending on your climate and weather exposure. Wet climates rust faster than dry climates.
Q: Can I use these on a rooftop or patio?
A: Yes! These are perfect for hard surface installations. The rust patina is stable and won't stain once fully developed.
Q: What's the soil capacity?
A: Varies by configuration. A 4'×8'×22" bed holds approximately 44 cubic feet of soil (about 1.25 cubic yards).
