That's good to know. I've been working from the sizes I found at metals4u which seem to do 6m lengths max. I'd like to try and source the metal locally so hopefully I'll find a friendly place that will cut it down for me too. My comment about trying to get all four out of a single length is a bit moot now anyway as I realized that I wouldn't be able to hit my 1220mm cutting target on X, I've just finished stretching the frame up to 1800mm and adding an extra support column. It really brings home how important it is to design before building.
