Ha ha! A length measurement is not very meaningful there, they should have given surface area to have much meaning. Also, I wondered why it went to Germany to be sawn?
The germans have very good sawmills, they see their forests as something that has economical value whereas people in the UK see them as places to go for a stroll on a Sunday afternoon.
It is not uncommon to measure timber in length bu you need to give the section for it to be meaningful.
I make a living by designing timber structures and I am still puzzled why the resource is not valued here. In general, softwood comes from Finland, processed material from Germany and Oak from France. It is next to impossible to source good quality Brtish timber not that timber is of bad quality but just that the forest industry is not very well organiised.
