Construction method for steel bench

The old bench... Served me very well over the past few years

Thanks hitch I was wondering would that be enough. I was looking and jacking the centre up with weight on either end.

Would bracing the corners at 45degrees be any use?

Been thinking about this sag in the bench and what materials I have spare. Would i get away with jacking the centre up level again and putting some 40x8 flat on its edge under my 40x40 frame.??

If you welded it up with the sag you might find that it won't straighten easily as you have created a curved laminate.

It's only tacked now. I think it's just the plate trying to retain its original shape and pushing down on the middle. I jacked the centre up off the lower centre crossbar and its perfect. I was going to put a brace in there but the lower cross bar is under constant pressure then.
