Tall bamboo or metal trellis/trellises (Thame OX9)

I am on lookout for a free tall bamboo or metal trellises if anyone is clearing/redoing their garden. They are to be for my no mans land planting pollinators patch so they don’t need to be a thing of beauty. Uglier/rusty the better to make sure no-one would want to steal them. Thank you so much for reading.
