These products have been developed to provide a structural wood column option that is much stronger than traditional solid sawn timbers without the natural splitting, twisting and movement experienced with a solid timber. Prime Columns are pressure treated to .23 pounds per cubic foot using a micronized copper azole  wood preservative. The .23 retention is recommended by the ESR-2240 ICC Evaluation Report as the retention for "Critical Structures" and is a much higher treatment level than typical pressure treated products. Additionally, the treated wood is Kiln Dried after treatment to provide stability, durability and an aesthetically handsome structural wood column option.
