Black Locust (Robinia Pseudoacacia) is the strongest and most rot resistant wood indigenous to North America. It makes an incredibly resilient and durable decking material that will remain beautiful and withstand years of outdoor exposure.
Nothing beats Black Locust for sustainability and durability. The wood is naturally rot-, decay-, mildew-, and insect-resistant — the perfect choice for outdoor projects in all climates. Other decking options are potentially hazardous and require significant use of energy, such as chemically-treated pine, heat-treated woods, and synthetically-developed composite decking materials made from plastics.
Building with Black Locust is also a sound environmental choice. Black Locust grows faster than any other known hardwood tree. Unlike Brazilian Ipe, Black Locust does not contribute to tropical deforestation. Black Locust is also known as false acacia, or Chinese teak (due to its resemblance to teak).
