Corten Steel Trough Planter | Ready Rusted

Corten Steel Trough Planters are an excellent choice when selecting metal planters for your outdoor space, due to their unique features which include an amber rusty exterior, exceptional durability and zero maintenance. The orange hues look beautiful against an abundance of green foliage, which perfectly highlight the planter’s copper tones. The industrial appearance of the planters also provide a captivating contrast to plants such as perennials and succulents. Corten steel is an incredibly long lasting material which means that once the planter is put in place, there is no extra maintenance needed.
The wide variety of sizes from 60x30x30 to 150x50x50 ensure that gardens can benefit from the planters being placed side by side along the edge of gardens or standing alone being a centre piece. Both of these options have an impressive architectural effect, as they can transform gardens into organised, compelling, striking places.

What is Corten Steel?  

Created in the United States in 1939, Corten or Weathering Steel is an alloy that forms a natural rust coating over time as it is exposed to the weather. The outer layer rusts forming a protective coating which prevents degradation of the steel inside. Corten Steel is used all over the world. Notably in the UK one of our greatest landmarks, The Angel of the North by Anthony Gormley is made from Corten. Other striking examples include the Chicago Picasso Sculpture and the Museum of Old and New Art in Australia.

How will your Corten Steel weather? 

1. In most cases your Corten Steel product will arrive un-rusted. It may have a slight patina or dark oily residue, this is completely normal.
2. As weathering begins, the residue breaks down and the rusty colour will start to appear. During this time, any run-off may stain stone or concrete surfaces.
3. After weathering (around 6-9 months), run-off may still occur but it will be minimal.

After your corten steel has arrived please unpack immediately, so that any moisture between the packaging does not remain sealed. If you do not do this, there may be irregular rust and stains.

What if you want to speed up the weathering? 

Fortunately science is on your side with a quick and easy fix. All you need is salty water. Dissolve around 1 teaspoon of salt in about 1 litre of water to get a weak salt solution. Spray or paint the solution evenly over your Corten Steel and that’s it! Repeat this process around 5 times over the period of a couple of weeks and you’ll see the rust developing in no time.
