Parallam® PSL Columns

Our highest load capacity

Parallam® PSL columns are strong and consistent. Our manufacturing process uses veneer strands, allowing a significant percentage of each log to become a high-grade structural member. Combine their great load capacity with the strength of Parallam PSL beams for additional possibilities.


  • Consistent performance
  • Available in long lengths
  • Excellent connection performance
  • Visually appealing in exposed applications
  • Efficiently uses natural resources
  • Comprehensive product warranty


Eastern Parallam PSL is manufactured at the Buckhannon, WV plant and provides enhanced protection from the elements when it matters most - during construction. You’ll see the difference from the start—thanks to our new and innovative proprietary sealant.
