Lumber vs. Round Wood
- Lumber is specifically defined as squared or rectangular wood.
- Round wood, like posts, is not considered lumber within the industry.

- Wood's cellular structure, composed of cellulose and lignin, is key to its strength and paper production.
- Separating cellulose from lignin creates pulp, the basis for paper and other composite materials.
