Where to find wood NTR/M?

[ToRy]

As the title says, where can I find NTR/M-treated wood?
I'm going to replace poles on a dock in saltwater, but can't find a lumberyard that sells the right wood.
I live in Gothenburg.

Thanks in advance!

With a bit of luck, there might be some niche bridge store somewhere on the west coast, if not, then it probably doesn't exist. Pressure-treated is a perishable and M probably sells no more than is made to order.

After a tip from a brewing neighbor, I went with standard pressure-treated NTR-A. The parts that will be continuously submerged in water were encased in plastic pipes. It remains to be seen how long it will last....
