Wood planks are flat, elongated pieces of wood that are commonly used in construction and woodworking. They are typically cut from trees and can vary in size, thickness, and type of wood, such as pine, oak, or maple. Wood planks are often used for flooring, furniture, and structural support due to their strength and durability. These planks can be treated or finished to enhance their appearance and protect them from damage. Common treatments include staining, sealing, or painting. Wood planks are a versatile material, making them a popular choice for both indoor and outdoor projects, including decks and fences.
