wood treatment
Lumber preservation process
Wood treatment is the process of applying chemicals, heat, or pressure to lumber to protect it from decay, insects, moisture, or fire.
Treated wood is common in outdoor construction—decks, fences, utility poles—where exposure to the elements would otherwise cause rot.
The deck boards need wood treatment before winter.
Pressure treatment forces preservatives deep into the grain.
