Don’t let the seeds you planted this season go to waste. DIY chicken wire fences are great for stopping critters, but few options keep your garden healthy as effectively and affordably as raised metal garden beds.
Because these beds lift your plants above the soil in your yard, which has tons of variables like hydration level and contaminants, you can ensure this year’s harvest only gets nutrient-dense topsoil. Raised metal beds also improve soil drainage and the looser soil offers better aeration than packed earth—all important things for keeping your plants healthy and growing.
Moreover, raised metal garden beds can save your joints—much like vertical gardens, they lift you off your knees for easier, more accessible planting and harvesting.
Whether you’re an amateur gardener looking to get started or a pro searching for an upgrade, check out the best raised metal garden beds to make sure this year’s harvest is bountiful.

What to Consider
Material and Design
Most of the picks on our list are made of galvanized steel. Galvanized steel is treated with a coating of zinc which protects against rust and corrosion. This extends the life of your raised metal garden bed and protects your soil from rust contamination. Because of the constant interaction with water, soil, and inclement weather, we only recommend garden beds made of galvanized steel or other treated metals.
In addition to coatings and treatments, many garden beds are made of corrugated metal. Corrugated metal has large waves or grooves bent into it. These waves improve the strength and structural integrity of the metal, so you can fill your garden beds to the brim with soil and plants without the metal bowing out or collapsing.
Type
There are two main types of garden beds: supported and containerized. Supported beds serve more like a border and soil barrier for your garden, with the bottom mostly open for free drainage and direct contact with the land.
Containerized beds are designed like large planters, with the entire garden held inside of it—no contact with the earth below. These beds have drainage holes and can move anywhere in your yard without significant disruption to the garden or ground, whereas supported beds are likely to become entrenched after a few years (especially if your plants have extensive root systems).
Containerized garden beds include elevated options, which are raised completely off the ground—usually several feet—and a great pick for those who don’t want to bend down at all. These are typically smaller, more mobile garden beds meant to move around to catch sunlight and keep your plants away from potential ground-level threats.
Size and Shape
The most common shape for raised garden beds are ovals, rectangles, hexagons, and squares. While the shape makes very little difference to your garden’s growth, they do make a difference in how you plant your seeds. Oblong shapes give you space to plant rows of veggies or herbs while more circular options might work better for flowers.
Pay close attention to the dimensions of the garden bed in relation to the size of your yard to ensure it fits well without overtaking all of your space.
How We Selected
We conducted extensive research across multiple gardening forums, hundreds of verified customer reviews, and trusted online publications to survey the metal garden beds on the market. We selected these beds based on their function first and foremost, paying special attention to the quality of the metal and how well the design works. We also took into account size, price, durability, and aesthetics. We made sure to include garden beds of different shapes and types to provide quality options regardless of your personal preference.

Best Overall
Land Guard Galvanized Metal Raised Garden Bed
Pros
Comes in five colors- 0.78 mm of sheet thickness for protection
Cons
- Tedious to assemble
Both the most popular amongst Popular Mechanics readers and our best overall pick, this raised metal garden bed from Land Guard provides exactly what you need at a very affordable price.
The 0.78-millimeter-thick metal prevents pests from breaking through to your plants and the galvanized exterior protects the metal from rusting or degrading over time. This raised garden bed also has a corrugated structure and oval shape that are designed specifically to withstand pressure from the soil and water inside. Even if you fill your garden bed to the brim with soil, it should hold together solidly.
At the same time, the open base allows for easy drainage while still protecting the roots of your plants.

Pros
- Internal stabilizing crossbar
- Comes in multiple sizes
Cons
- Metal exterior is too thing for some users
This raised metal garden bed offers the protection, elevation, and size for your garden to thrive—all for a reasonable price.

You can grab this garden bed in two different sizes, including a two-pack option if you’re ready to build up your garden right away. That said, make sure to not pack those gardens too tightly, as the metal plates have been reported to bow out.

Cons
- Lacks central support or stabilizing beam
The powder-coated steel plates of this metal raised garden bed from Best Choice Products protect your plants from the weather outside as well as the dirt.

The garden bed actually has designs to protect you as well. The squared-off corners reduce cuts or scrapes that happen on sharp edges, and the rust resistance keeps you from handling dangerous, corroded metal.
