Cor-Ten Steel. What’s the Difference?
We get a lot of questions about Cor-Ten Steel (a/k/a weathering steel plate or high-strength corrosion resistant plate), mostly from our landscape designers and contractor clients, on how to use it, what’s the difference between this and raw steel. If you’re not familiar, here’s what makes this material special:
- It has a beautiful and natural rust finish which has a refined rustic look.
- It starts out looking like raw steel, but once cleaned of all oils, will quickly (within one month) take on a rust finish.
- The surface is ‘reactive’, so the rust finish is variable and changing.
- It’s core is non-corrosive, therefore it will withstand the elements without degrading like raw steel.
- It’s available as a sheet material in thicknesses of 3/16″ to 5″.
- Will it ‘drip’ rust and stain? Yes.
- Can I use it as a fountain? We haven’t. A lot of designers like this look for water features, and we’ve seen it used for fountains, but beware. Your water will most likely be brown and cloudy, and this can cause problems for your pumps.
- Is it more expensive? Yes, but worth it if you want it to last forever.
- If used for a planter, won’t the roots get too hot? Maybe. We’ve used bubble wrap or other filter fabrics to line our planters.
