Robinia wood is becoming increasingly popular. The wood, which also grows regionally, not only impresses with its high wood hardness, but the biological properties of robinia also make it a sustainable and environmentally friendly alternative to tropical hardwoods.

The ecological trend wood from Europe
The search for hard and resistant woods often leads to wood species from tropical regions. In addition to the high prices, these woods must also be imported via long delivery routes and thus also pollute the environment.
Robinia wood is an alternative that is not only cheaper and even regional, it is also in no way inferior to hardwoods from overseas. Untreated, Robinia wood can last up to 25 years and is therefore ideal as construction wood for outdoor use.
Garden furniture, play structures, huts, fences and much more can be built with robinia wood. Many of our customers have already recognised the advantages of robinia wood, convince yourself of our wood with the highest quality.
The origin of the black locust
Originally from North America, the black locust was first cultivated in Europe as a park and avenue tree.
Due to its very good natural durability and high mechanical characteristics, Robinia has also established itself as an important commercial tree species in recent decades. The quality of Robinia wood is largely determined by the stem shape of the tree, which often has a crooked, eccentric growth, which limits the yield of the assortments.
Robinia wood on the German market currently comes mainly from the south-eastern European region (Romania and Hungary) and from Brandenburg.
Grain & Colour
Due to the high density of Robinia wood, its structure is very fine. The bark is very coarsely structured and thick. Depending on the origin and the environmental conditions, the colour of robinia wood can vary from a golden yellow to a honey yellow tone.
Special features of robinia wood
The advantages of robinia wood are obvious and should convince everyone to choose a native wood like robinia.

Robinia pseudoacacia, family Fabaceae- Faboideae
Eastern North America, cultivated worldwide
Robinia, false acacia, common Schotendorn (D), robinier (F), false acacia (GB), black locust, yellow locust (USA), robinia (NL, I), salcam (RO), fehér akác (H).
Medium-sized tree of 12 to 25 m (maximum 30 m) height and 30-60 cm diameter; branch-free lengths usually relatively short, from 2 to 6 m, in closed stands up to 10 m; often crooked-shafted, partly out-of-round and tension-backed. Planned selection and silvicultural maintenance measures in plantations can positively influence shape and dimensions.
Colour and structure
The light, narrow sapwood contrasts clearly with the yellow-green to olive-brown heartwood, which darkens to golden brown. The large, strongly thylled early wood pores are arranged in rings and surrounded by light storage tissue. The late wood pores are also associated with light parenchyma cells and partly grouped in diagonally running bands. The grain pattern is often irregular due to the crooked or eccentric growth form.
