    I have a client who is looking for a sign that will rust over time... So my google-fu turned up Cor-Ten (or weathering) steel. Has anyone used this material? How have you cut it? We can't cut steel in house, so I'll be subbing at least part of this job out.

    My original design called for a steel frame / border with finished wood panels, but that would require the welds to be perfect. AND this sign is going to be about 3x10 and projecting off a wall (Oy, I have no idea how they were approved for such a huge, projecting sign, but they got the go-ahead, so here we are!) So I'm thinking about flip-flopping my materials... wood frame, steel (not structural) interior.

    Any advice?

    No need for exotic "weathering steel". Hot or cold rolled anything will work just fine. I've done it. The other thing I've done for the panels themselves is my version of Photoshop Rot. From a few feet away you would never know it's a digital print on acrylic. Nice and crispy. LOL

    The only difference is that Cor-Ten rusts to a point and then "self-seals" and stops rusting. Regular steel will continue to rust and possibly stain or damage anything that that rust runs on to.

    The Cor-Ten is typically flame cut.

    From what I read it was to be a steel frame with wood panels thus my suggestion. Using a rot 'n' stop for a panel is another thing all together.

    The welds/frame don't have to be pretty just structurally sound. The cobbled together look can add to the theme.

    Your customer will have to put up with "rusty brown" until it reaches the dark patina. Regular carbon steel stays ugly brown. I'd go with the Corten.

    You should be able to have Corten laser or abrasive waterjet cut.
