This improves their suitability for particular end uses, especially in demanding structural situations, but may also be designed to improve other characteristics such as durability and also the following ;

• to overcome the dimensional limitations of sawn timber

• to improve performance; structural properties and stability

• to transform the natural orthotropic product into one with more homogenous properties
