We Transformed Scrap Sheet Metal into Budget-Friendly Raised Garden Beds
Every year, my husband and I attempt a garden, and every year it starts out pretty strong, then slowly turns into a bit of a weed-filled, slug-infested jungle.
This year, my husband has decided that the year of the raised bed will solve all our problems. Weeding will be easier, bending over to reach the produce and inhabitants will be easier, and most importantly, growing and harvesting our bounty will be even easier.
The problem he encountered was building the raised garden beds. Traditionally, he tells me, raised garden beds are made of cedar or pine because using treated lumber can leach chemicals into the soil. (I should add here that my husband is a fourth-generation farmer, so that is why I am leaning on him as an expert here.)
Okay, but back to the raised bed business. So, treated lumber is not ideal because it can leach yucky chemicals into the soil. However, like many families, we're on a budget, so we didn't want to buy more cedar or pine. Instead, my husband took a look around our yard, realized he had tons of scrap metal sitting around, and had an epiphany:
Why not create a raised garden bed using scrap metal?
"I never considered making them this way," my husband explained. "I never thought of using steel because everyone makes them out of wood. But you can make it as wide or as tall as you want. It's actually a raised bed."

After a little bit of online research, he decided the idea was worth pursuing. He concluded that a sheet of steel, a common product available at any home store, or even scrap metal, because it's used in construction, would make the ideal raised bed container.
The sheet of steel becomes the lining of the raised bed, enabling treated lumber to safely be used as the frame. When completed, because the steel serves as the liner, the soil never comes into contact with the lumber, freeing him to use cheaper lumber without fear.
To create a raised garden bed from scrap metal, my husband first built the frame from treated lumber. He used 2 x 4s made of treated pine.
Next, he cut the steel to size. You will need special tin snips to buy them or invest in a tool to cut the steel (and always wear eye protection when cutting sheet metal).
From inside, he used sheet-metal screws and fastened them from the inside out. This method is ideal because it ensures:
- The fasteners will never come apart due to ground expansion or container filling, because the dirt provides constant outward pressure.
- The metal protects the soil from the treated lumber.
Because our raised bed is a long rectangle, he also added a middle support piece for strength and stability.
According to my husband, the benefits of using scrap metal for a raised bed include:
- It's cost-effective, because you can use scrap metal or buy a sheet of steel easily.
- It's long-lasting, and the wood won't corrode away.
- It provides protection from treated lumber leeching into the soil.
- It can be easily customized to size or specific dimensions.

Last, be sure to cap the steel's edges before use, so no one is cut by the sharp edges. Capped edges are not pictured in our bed yet because it's still in progress. Be sure to cap your edges before use. And happy planting!
