How many types of treated wood are recognized in construction?

In the context of construction, two main types of treated wood are recognized: pressure-treated wood and chemically treated wood. Pressure-treated wood is commonly used for outdoor applications because it is infused with preservatives under high pressure to resist decay, insect damage, and other environmental factors. This makes it ideal for structures like decks, fences, and posts that are exposed to moisture.

Chemically treated wood, while also infused with preservatives, may refer to different types of treatments that determine specific uses, such as for marine applications or for other specialized purposes. This classification helps builders select the appropriate type of treated wood according to the demands of their project.

By understanding these two types, construction professionals can better assess which materials will be suitable for particular environments and requirements, ensuring durability and longevity in their building practices.
