LEED Wooden Plaque (Black Locust)

LEED Wooden Plaque (Black Locust)

We have chosen European-grown Robinia pseudoacacia a.k.a. Black Locust, (read more below) for our first wooden plaque


To the best of our knowledge, no similar product is available anywhere else.


This is our most environmentally friendly LEED certification display and launches our "Greeen line" of products with improved environmental characteristics.


our Robinie wood plaques have the same mounting options as our aluminum plaques.


these plaques are

  • made from 5 cm thick, joined slabs of wood from reforestation areas in southern Romania.
  • CNC milled with double-depth engraving for better character perception
  • hand finished
  • treated with natural linseed oil for additional protection and a glossy sheen



Many countries have strict limitations as to the import of products made of wood. For this reason, this plaque is currently only available in the EU.  If you are intersted in purchacing one in another region, please contact me before purchact so that we can clarify the customs regulations.



More about Robinia pseudoacacia

This very common plant, also called Black Locust, is native to North America, and has been cultivated as a decorative plant in Europe since early 1600. It was the “tree of the year” in Germany for 2020.

The wood is pale yellowish brown, heavy, hard, strong, close-grained, and very durable in contact with the environment. It has a specific gravity of 0.7333, and a weight of approximately 732 kg m3. The very high Brinell hardness of 46 N/mm² makes it an excellent candidate for various production methods.

Very low deformation and the very low shrinkage of Robinia wood. Even if it is heavily soaked, it remains very dimensionally stable.

Robinia wood shines with a very high natural resistance, which makes an additional wood preservative treatment unnecessary. Robinia wood can also withstand prolonged exposure to weathering and moisture, as well as frost and cold. Completely untreated, its service life is considered to be between 15 and 25 years.


Advantages of the plant

  • can be used for erosion protection and to enrich barren or sandy soils or for reforestation/land reclaiming.
  • the wood is extremely hard and weather resistant without chemical treatment
  • A quick growing, very successful species which can thrive in places where others can not
  • binds nitrogen in the soil


Disadvantages of the plant

  • Is considered an invasive species in some areas, as it can crowd out other vegetation.
  • Parts of the plant are poisonous, especially the seeds and Bark which can be fatal for horses.
  • Only moderate biodiversal benefits.
