Not appropriately. It is not a structural material. It has enormous amounts
of creep. Cut a slice 25 to 50 mm wide and a 1 m long and support it on both
ends, leaving it free in the middle. Come back after a couple of weeks of
humid weather and check out the sag.

Actually, it has been used but it requires suitable reinforcing as in sturdy
veneers on both sides and/or supporting logs underneath.

And it's really, really heavy.
