Why chestnut?
Chestnut is a hard wood and well known for being very strong, durable and long lasting.
Chestnut’s important difference to Oak can be found in the post seasoning density: Oak turns out to be much heavier than Chestnut. With a much lower density, the lightness, together with its high resistance makes for a great structural advantage of chestnut.
Chestnuts high resistance to decay makes it ideal for outdoor use in fences, sheds, gateposts etc.
