Oak edge boards are mainly used in the civil engineering sector. This is because these boards are a cheaper alternative to the much more expensive tropical hardwood.
For hydraulic engineering, it is often possible to use a cheaper quality timber where fringes and knots are allowed. These second-quality oak planks are significantly cheaper than our first-quality planks and are also very suitable for wattle fencing. It is therefore not surprising that these planks are increasingly used in shoring.
