Preservative-treated wood is a type of wood that has been artificially processed to feature anti-corrosion, anti-termite, and waterproof properties. The introduction of preservative-treated wood has made a significant contribution to saving timber. Now, it's highly eco-friendly, so some people even use it indoors during renovations.

Preservative and termite-resistant, as the name implies, preservative wood naturally offers preservative properties, making it a popular choice for outdoor flooring materials. Preservative wood flooring effectively resists microbial attack and termite infestation, while also being waterproof and termite-proof, allowing it to withstand harsh outdoor conditions without much maintenance. However, as outdoor preservative wood, it undergoes significant thermal expansion and contraction without special control, leading to severe warping. When installing preservative wood flooring, it typically needs to be laid with gaps and elevated like a perforated surface, which can be easily flipped over for cleaning or to retrieve dropped items.

Preservative-treated wood flooring is one of the primary uses of this material. Beyond that, preservative-treated wood can also be used to manufacture various outdoor items such as tables, chairs, swings, grape arbor, and even wooden houses, much like what we often see in foreign residential gardens. Now, an increasing number of people in China are living in villas, and setting up some preservative-treated wood furniture in their own gardens is also a charming option.
