TBH Mark, aside for the Chinese crap, most of it was better quality than 'home grown' ....
once had a bar of Russian

305 x 305 UC (my grading beam is made from the offcut) .... was absolutely perfect - bang on dimensional spec. and as true as it could possibly be - square and arrow straight which for a 16.5m bar was a bloody miracle ....

.... the Spanish mills also produced some very tidy product.
had 22t of 457 x 152 x 60 UB in once, for a long travel rail system, for a gantry job .... each length had to join to the next down a building with a crane rail fixed to the top ..... the centre web was between 12 and 18mm off centre .. you can imagine the issues that would have caused .... the lot went back - British mill - quality control .. non existent .......... the Spanish stuff that replaced it was cock on

....... they killed them selves
