CDB2 (op=op)

Corten Steel, also known as weather resistant steel, is a steel alloy made of iron which has copper, silicon, nickel and chromium added. As soon as Corten Steel is exposed to the elements it will naturally weather and develop a protective layer of rust, this can take several months. This natural fixed coating of rust provides protection against further corrosion. 

• Varnish
• Rust accelerator

The standard material thickness of our Corten Steel planters is 3mm. 

Important: 
• The products are delivered un-rusted 
• Ensure an adequate drainage (holes in the bottom as standard), no excess water should remain in the planter, the combination of oxygen and earth will rust the planter further. 
• Do not use hydro grains as they hold water 
• The products must be unpacked immediately after delivery so any moisture between the packaging and the product is not sealed. This will result in irregular rust and stains.

Advantages: 
• Very strong and wear-resistant 
• Low-maintenance 
• Weatherproof and durable material 
• Warm and natural appearance 
• Optional polyurea coating on the inside 
• We only use Corten Steel category A type S355JOWP 
• We recommend ‘Owatrol’ varnish which will stop the planter from rusting any further (available from us) 
• 5 year warranty

Planting advise: 
• Provide the bottom with a layer of Ø35 mm pebbles 
• Do not use an overflow pipe (no water may remain in the planter) 
• Place anti-root cloth over the layer of pebbles 
• Top up with earth suitable for chosen type of planting
