  • Corten Rectangle Planter

This rectangular metal planter box is ideal for adding charm to any space, separating areas, or enhancing your home or office with a one-of-a-kind structural piece.

With a series of these planters, you can create a barrier between a main outdoor room and the outdoor one. Separate an outdoor sitting area from the food-prep zone to achieve the ideal balance of open-concept and dedicated spaces.

Alternatively, to direct foot traffic, use a series of rectangular planters to create flow and direction. The design possibilities are endless, and this highly functional rectangular metal planter box will look naturally beautiful while performing whatever function you’ve assigned. Corten steel, also known as weathering steel, is used to construct it.

Our modern Corten Steel Rectangular Planter is ideal for your garden, whether modern or traditional. The vibrant Corten Steel on these planters draws attention. We have the right size for you, whether you’re planting flowers or small trees.These lovely planters are made of 12- and 14-gauge Corten Steel, a solid steel alloy that will weather and develop a beautiful protective layer of rust over time.

Corten Square Planters

  • Corten Square Planters

Corten Steel Planter is an excellent addition to any outdoor space, providing a weathered rustic yet stylish look. These planters, which come in modern square, cylindrical, and multi-level designs with a rusted patina finish, are ideal as patio accessories.

All Metallic Series planters are made from a thick gauge, fully seam welded Corten Steel base and have been proven to withstand weather-related issues such as cracking in both winter and summer months.

The Corten steel base of the planter ensures that the structure will only show surface rust for aesthetic purposes and will never rust through over time. Metallic Series planters are ideal for residential and commercial settings due to their increased durability. Perfect for creating a beautiful home with minimal effort.

“Weathering” means that these steels are more resistant to atmospheric corrosion than other steels due to their chemical compositions. Because when exposed to the elements, steel forms a protective layer on its surface. The protective layer’s corrosion-retarding effect is caused by the specific distribution and concentration of alloying.

The protective layer’s corrosion-retarding effect is caused by the specific distribution and concentration of alloying elements in it. When exposed to the elements, the layer protecting the surface develops and regenerates continuously.

The steel is allowed to rust for the ‘protective’ coating to form. With National Planter Supply, you can be confident that you are getting the perfect design, durability, and convenience. As shown in the image, all Corten steel planters are shipped in their raw steel state and will gradually develop a rich patina finish over time.
