Introduction to Wood Species and Grading

This presentation will provide an introductory review of wood species and
grades, and the impact of these factors on structural properties and
durability. Grading rules, design properties and identification stamps will
be discussed. Wood species common in different regions of the country
will be highlighted, as will the varying degrees of natural decay resistance
associated with certain species.

Learning Objectives

  1. Review the significance of wood grading rules and grading agencies to
    structural design properties of wood framing members.
  2. Discuss available wood species as well as methods of grading and
    identification for common wood framing material.
  3. Highlight the range of natural decay resistance inherent in common wood
    framing species.
  4. Explore the impact that regional climatic conditions have on growing
    conditions and product availability.
