possible to hammer a nail within it without drilling a hole first.
The timber does not rot even when in close contact with damp earth.

Maintenance is minimal. The timber requires no treatment but occasionally
the bolts have to be tightened, particularly after about six months
when the timber sometimes shrinks.
