Building a corten steel outdoor plant box is a fantastic way to add a modern, industrial touch to your garden or patio. Corten steel, known for its weathered rust-like appearance, is durable and requires minimal maintenance. Here’s how you can create your own:

1. Gather Materials & Tools:

- Corten steel sheets (16-18 gauge recommended)

- Angle grinder or metal shears

- Welding machine (or rivets for a no-weld option)

- Measuring tape, square, and marker

- Drill and screws (if not welding)

2. Measure & Cut the Steel:

- Decide on the dimensions of your planter (e.g., 24"L x 12"W x 16"H).

- Mark and cut the steel into panels: two long sides, two short sides, and a base.

3. Assemble the Planter:

- Weld or rivet the side panels together at the corners.

- Attach the base panel, ensuring drainage holes are drilled if needed.

4. Finish & Weather the Steel:

- Corten steel naturally rusts over time, but you can accelerate the process by spraying it with a saltwater solution.

- Place the planter in your desired outdoor location and let it develop its signature patina.

5. Add Plants & Enjoy:

- Fill the planter with soil and your favorite plants or succulents.

This DIY corten steel plant box is not only stylish but also long-lasting, making it a perfect addition to any outdoor space.
