Modern wooden arbors not only have a very beautiful, practical look. They are also durable, they are not afraid of moisture and temperature changes. Even the fire is unstable to them, as they say and do not drown in the water and do not burn in the fire. The point here is that a real arbor is impregnated with special liquid substances that go deep into a tree. These impregnations not only do not allow moisture to penetrate into a tree, but also fire cannot fire such a product.
