Product Description

6x6 x 10' Ground Contact Pressure-Treated #2 Fir Lumber is a heavy structural post and column designed for exterior applications requiring direct ground contact protection and dependable load-bearing support.

This lumber is pressure treated to a CA-C .15 retention level for ground contact use and is incised to improve preservative penetration. The brown-tone treatment provides a uniform exterior appearance while protecting against fungal decay, rot, and termite damage.

Manufactured from fir species and treated for durability, this timber is commonly used for deck posts, structural columns, pergola supports, and other ground-contact framing applications where strength and long-term decay resistance are essential.
