Spruce wood is one of the most important woods in the German wood trade and the most important German wood supplier. A third of the forest area in Germany is covered by spruce. As one of the cheapest European woods, it is used as pulp for paper production, as pallet wood or construction wood. Due to its low resistance (class 4), it can only be used as decking wood after impregnation

The German plantation tree

Every third tree in Germany is a spruce. Similar to plantain wood in the tropics, spruce is also usually planted in Europe under heavily cultivated conditions. A spruce forest usually stands in rank and file. Due to regular thinning, the forest floor is hardly covered by old growth. The trees grow relatively quickly for the temperate climate conditions.

Spruce wood is by far the most commonly used building and construction wood in civil engineering. However, it should not be used outdoors without protection, as it is not very durable.

Spruce decking boards

Despite its poor outdoor durability, spruce wood is also offered as a very cheap decking board. In order for the wood to last 5 to 8 years, it is pressure-treated. After that, it usually has a greenish color. In addition to its low resistance class, the strong resin formation of the wood and the tendency to splinter speak against outdoor use.
