Pressure Treated

Pressure treated Douglas Fir is the most common choice for deck foundations and other structures that need to withstand moisture. This lumber is treated with chemicals that allow it to resist damage from moisture, fungus and insects. It should not be used where people will come into direct contact with it, such as decking, railing, benches, etc. Likewise, it cannot be used for gardens used to grow food. Care should be taken when handling and disposing of pressure treated lumber. Most pressure treated lumber has a green cast. Much of our Doug Fir is treated with Alkaline Copper Quaternary (ACQ)* and has a warm brown color that blends well with untreated wood.
