Spruce wood is one of the most important woods in the German timber trade and the most important German timber supplier. One 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 timber. 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 planted woods in the tropics, spruce is also usually grown under highly cultivated conditions in Europe. A spruce forest usually stands in rows. The forest floor is hardly covered by old wood due to regular thinning. The trees grow relatively quickly for the temperate climate conditions.
Spruce wood is by far the most commonly used building and construction timber in building construction and civil engineering. However, it should not be used outdoors without protection, as it is not very durable.
Spruce decking boards
Despite its poor durability outdoors, spruce wood is also offered as a very affordable decking board. The wood is pressure impregnated to give it a durability of 5 to 8 years. After that it usually has a greenish color. In addition to its low resistance class, the strong resinification of the wood and its tendency to splinter also speak against its use outdoors.
