Robinia is characterised by its resistance and durability. Its trunks are formed entirely by heartwood, the hardest part of the trees. It is not treated and the only maintenance that needs to be done is cleaning. In the case that it is painted, only water-based paints shall be used. It is a living material, therefore it is possible that small cracks appear that do not affect the durability that can reach 20 years.
Edge detailing: Natural. No treatments. Smooth border finish.
