Why Southern Pine

Green Building


Southern Pine forests are some of the most productive and sustainable timberlands in the world, capturing large amounts of carbon from the air and storing it in lumber used every day. It’s also grown and manufactured in the Southern United States, further improving local economies, reducing transportation costs, and minimizing environmental impacts.


Southern Pine

Southern Pine lumber has been popular since colonial times and remains the preferred choice for today’s design/build professionals. One of the most reasonably priced options, it is dependable for everything from building a deck to framing a five-story residential complex. 

Latest Design Values

The lumber industry invests millions of dollars in ongoing testing to create the most accurate and reliable structural lumber design values. The most recent design values, which went into effect June 1, 2013, were determined from destructive tests of more than 7,400 full-size samples of commercially produced Southern Pine, resulting in more than 300,000 data points for visually graded Southern Pine dimension lumber. 

Cost Savings

Wood products are the most cost-effective building material on the market. Southern Pine is competitively priced because of an abundant timber supply, manufacturing expertise and established market preference.

Proven Quality

Southern Pine lumber is graded in accordance with the Southern Pine Inspection Bureau (SPIB) Standard Grading Rules. These product quality standards inspire confidence among the manufacturers, buyers, and consumers who rely on Southern Pine and ensure a sustainable, successful future for the industry. 

Best Treatability

Southern Pine’s unique cellular structure permits deep, uniform preservative penetration, making it the preferred species for pressure treatment. In fact, approximately 85% of all pressure-treated wood produced in the U.S. is Southern Pine.

Density, Strength, and Stiffness

Southern Pine has the highest specific gravity of all common structural lumber species, providing superior fastener-holding power and load-bearing capacity. Users can choose from a variety of visual and machine rated grades providing a range of dependable strength and stiffness properties to meet the needs of any project.

Natural Beauty

Southern Pine has a distinct grain pattern and an appealing golden color, making it architecturally appealing.

Widespread Availability

Southern Pine is an abundant and renewable resource, growing across the Southern United States from East Texas to Virginia. Hundreds of Southern Pine lumber manufacturing facilities operate in this area, too, creating ready availability to major markets.

Dimensional Stability

Southern Pine dimension lumber 2″ and less in thickness must be dried to a maximum moisture content of 19%, which minimizes the shrinkage associated with green lumber and provides long-term stability.
