Laminated columns are manufactured by gluing together multiple individual treated boards under pressure. This process creates a stronger, straighter, more stable post.
Superior Treatment Penetration: With a solid post, CCA (copper-based preservative) treatment cannot fully penetrate to the center. Laminated columns achieve 100% CCA protection because every board is treated before assembly.
Reduced Movement: The lamination process dramatically reduces cracking, splitting, and twisting over time.
Materials: #1 grade lumber, treated for above-grade exposure (though the bottom is also protected by your chosen foundation system).
