I don't suppose you remember which make of arch that is NS?

Anyone do wrought iron work locally to you MoS? Might cost a little more buy you'd get a nice garden feature and it would certainly last longer.

Don't know if it helps, but the trees are pretty self supporting and the arch is just a shape to train them to 

I guessed as much, but wouldn't want the arch collapsing from underneath in 3 years time 

Lardman, good idea, but when I last looked, it was expensive here  .................I'll just keep looking
