• @hugo7 Ah i didnt realise it changes colour like that. I also just found out, as it rains you get run off from the coating too which wouldnt be so good for the garden i feel.

    After doing some more research I found this stuff

    https://www.steelroofsheets.co.uk/products/corten-effect-corrugated-sheets/

    Which is a poweder coated effect on galvanized steel, which means its stable in its colour and finish for 25 years. Also works out a bit cheaper than actual Cortan too... that being said it would still cost £1500 for us to do one side of the garden.

  • I'd be sceptical of that powdercoated stuff, the whole point of (aesthetic) corten is to develop a unique patina over time. I'd put money on the fake ones being very uniform and not very nice. Think wood-effect melamine vs solid timber.

  • Corten or nominally weathering steel is beautiful and functional. But yes, it can run off, it needs design thought. I did my thesis on it and application on bridges.

    I'd probably just get some nice timber boards that will weather for the garden.

  • cheaper than actual Cortan too... still cost £1500 for us to do one side of the garden.

    Yeah... I mean you can see why the concrete post + boards is so popular. Once you're looking at those numbers you can't help but think brick (which is really the best solution) is worth looking into.

    Our neighbours have good quality feather edged boards and I've never seen or smelt them through it

  • Any runoff would do wonders for the hydrangeas.
