• You won’t get galv to rust, unless you sandblast the galv off and end up with plain steel. It can be blackened though.

    That corten roof sheet looks great, you may spot it popping up a coffee bar front sometime soon…

  • which id have to chemically treat to get it to rust...

    By this I meant chemically strip the galvanzing off allowing it to rust, as opposide to mechancially like sand blasting - Either way, it sounds like too much effort. I cant see anywhere to get plain steel in corrugated.

    For futher context, the pannels are going to attached to exisitng posts and supports so they dont need to be strucutal at all.

    Do you happen to know how much it costs per sheet out of interst?

  • @spotter you might find some "rustic" corrugated roofing sheets from marketface or gumtree. Probably need to pick and choose the best ones based on look and condition.

  • I was curious enough to give them a call. Corten sheets are 2400x1100 and £198 ex VAT and carriage. He didn't quote but a double palette is around £12o ex VAT from experience.

    Cheapest inc. carriage for galv corrugated is Metals4U
