These untreated and durable robinia sanded posts 18-20 cm are sanded and unpointed as standard. Robinia wood is also known as the only European hardwood species and therefore falls into durability class l/ll. This means that the robinia posts have a lifespan of approx. 20 years. This makes these robinia posts very suitable for use as garden posts, meadow posts or for playground equipment. The spin-free robinia sanded posts 18-20 cm may have curvature due to their natural appearance. This makes them look playful and you often see them at schools and nurseries. The core of the trunk remains after it has been sanded spider-free. The robinia posts have a gradient and are not equally thick along their entire length. The ends of the robinia sanded posts are at right angles on both sides.
