Why Corten Steel?

Corten (weathering) steel is specially formulated to resist corrosion and surface damage. As it weathers, it forms a protective oxide layer that prevents further rusting — giving your garden a warm, rustic look without sacrificing durability.

All Corten steel planters are supplied raw with no patina. The patina will develop over time.

All sizes can be ordered with or without the baseplate.

• The baseplate allows for more versatile positioning options where it is beneficial for the bottom of the planter to be enclosed such as a patio or deck.
• Without the baseplate is best if the planter is going to be installed in an existing garden where the plants would benefit from being able to reach their roots into the soil below the planter.

Assembly

• Unpack the kit.
• Connect a short side to a long side using bolts & nuts.
• Leave all nuts slightly loose.
• When three sides are connected, slide in the baseplate (if you chose to have one).
• Connect the fourth side in the same manner.
• Tighten all the nuts.
• Fill & plant your new planter and enjoy!
