1. Gaintex 9-in-1 Galvanized Steel Raised Garden Bed
This heavy-duty bed is constructed from solid steel with a durable powder-coated white finish. The tall sides (1.5 ft) and large footprint (8×2 ft) provide ample space for a wide variety of plants. Assembly is straightforward though the finished size makes it difficult to move around the yard. The thick galvanized steel construction should withstand many years of use without warping or rusting.
2. Best Choice Products 4x2x2ft Metal Raised Garden Bed
Sturdy powder-coated steel panels lock together tightly while remaining easy to disassemble for storage during winter. Slatted sides provide both plant support and airflow to roots. At just 4×2 ft, it’s best for containers or smaller herb and vegetable patches.

One of the best values, this 48″ x 24″ bed grows a huge quantity of produce which can hold 5 cubic feet of soil in total. Assembly requires no tools and the parts connect securely using bolts. The vertical steel sides allow full access, while the classic galvanized finish protects against rust without needing paint.
