Wood is one of the oldest and most versatile materials used by humans. It comes from trees and is used in construction, furniture making, tools, and many other products.
▸ Hardwood — Wood from deciduous trees (those that lose their leaves in autumn), generally denser and more durable, like oak, mahogany, and teak.
Example: Used for high-quality furniture, flooring, and structural beams.
▸ Softwood — Wood from coniferous trees (evergreens), generally lighter and less dense, like pine, spruce, and cedar.
Example: Commonly used for construction framing, paper production, and less durable furniture.
Understanding the properties of different types of wood helps in selecting the right material for a specific project, considering factors like strength, durability, and appearance.
