Robinia is a Hardwood Timber that is robust enough to stand up to the elements the British weather can throw at it. Due to its extreme hardness and toughness, it is difficult to work and tends to warp. So it was used only in mining, for example, to reinforce tunnels. After all, robinia wood is sturdier than oak! These days, robinia is often used as a teak wood substitute, mainly for garden furniture, playground equipment, and hydraulic engineering. ESP Play Parks specialise in Manufacture, Design and Installation of Robinia Timber Play Equipment for use in public playgrounds and play areas throughout the UK.
