The Vertical Grain Profile

Vertical Grain Terrace decking Douglas fir

The vertical grain decking floorboards are quarter sawn so that the year-rings run in a 40- 90° angle to the board surface. This straight pattern provides an amazingly minimalist design.


Wood is anisotropic, which means that its characteristics are directionally dependent. In the case of quarter sawn timber the anisotropy is particularly beneficial for the durability and stability of the floorboards , due to the vertical grain pattern. That way also, the chance of splinters is highly reduced.


Our forestry experts are always seeking out the best Douglas fir logs available. That way, we can supply floorboards that appear homogeneous and have a calm surface.


The production of such boards is very time consuming and costly, which is why we offer them to meet the highest demands, that are meant for terrace deckings. Further information to the dimensions and surface possibilities follow:
