There's a father/daughter team around here that has a small business and they take old donated cast iron benches and rebuild them and sell them for habitat for humanity. The benches weigh a ton so probably cost prohibitive to ship but might give you some ideas. We had them rebuild a bench that was totally destroyed that was in the yard of our first house together and was completely falling apart. No wood left at all. We were using the iron pieces to hold down the kids bball hoop... Now it's a badass bench with black, purple, and gold details and lives in our garden. I'll get a picture of it tomorrow when it's not dark outside
