Beams and structural building timbers are available in sizes up to 20 feet long.
Longer beams can be made by special order. Shapes available are straight, tapered or octagonal. Finish can be rough cut, fine or rounded edges made with a router.
Douglas Fir or Cedar is most common. Air dried, not kiln dried, so there is typically no cracking or checking. Consequently, when ordering air dry, allow 6 months’ time. Unless the beam you want is already in stock.
