Why is a manufactured board used instead of natural timbers?

Manufactured boards, such as plywood, MDF, and particleboard, are often used instead of natural timbers due to their consistent quality and uniformity, which minimizes defects and variations. They are typically more cost-effective and environmentally friendly, as they can be made from recycled materials and utilize fast-growing wood species. Additionally, manufactured boards can be engineered for specific properties, such as moisture resistance or strength, making them suitable for various applications where natural timbers may not be ideal.
