Hello dear people I am looking for who has already had experience with rusted frames of semi-trailers. My semi-trailer has now no longer got a TÜV, because various rust spots on the frame (only the outside frame, but once completely around and probably also so that the frame should be completely replaced) have occurred. Now I think about how I proceed – has someone already had experiences in this regard, also with regard to the price? dates to this: 1987 year of construction, 9, 60 m long, 2.45 m wide. Thank you for your answers!
