Building Materials at the Requarth Co. 

Grading lumber products establishes quality control standards among mills manufacturing the same or similar woods. These grades provide a dependable measure for determining the quality of lumber.


The Western Wood Products Association (WWPA) sets official grade rules, conforming to American Lumber Standards, for mills in 12 western states. The WWPA grade stamp, visible on White Pine, Spruce-Pine-Fir and other western species sold at Requarth Lumber, is assurance of its assigned grade.


The Southern Pine Inspection Bureau (SPIB) publishes grading rules under which more than 95% of the production of Southern Pine lumber is sold. To qualify for a SPIB grade-making license, a mill must have well-established credentials in manufacturing, seasoning and grading.

Preservative Treated Decking 

Treated lumber protects wood from termites and fungi — two of wood’s most destructive enemies. At Requarth Lumber, we stock preservative-treated wood products. We stock both 5/4 x 4 and 5/4 x 6 Premium Southern Yellow Pine (SYP) radius-edge deck boards. Additional lumber materials are available upon request. Please ask your salesperson. 937-224-1141    


Preservative Treated Deck Framing and Timbers  

As the industry converted to above ground contact 2x6, 2x8, 2x10, & 2x12 material in the early 2000s we held strong and kept our treated 2x6, 2x8, 2x10, & 2x12 rated for ground contact because we know this material builds a better, longer-lasting deck.  


Fire Retardant Treated Lumber 

Fire-retardant treated (FRT) wood is commonly specified for projects with stringent fire safety requirements. These include nursing homes, college dormitories, commercial offices, shopping malls and government buildings. Customers typically purchase FRT lumber for sheathing, subflooring, joists, studs, blocking and furring. Additional lumber materials are available upon request.
