Pressure treated decking types; Douglas Fir has a higher percentage of heartwood than many other species of wood. Manufacturers have to make changes to the preservative to maximize penetration and retention levels. Manufacturers often use an ammonia base as the carrier with preservative and this change increases the corrosive quality of the preservative. This corrosive nature can be short or long term
Pressure treated lumber was most steeped chromate copper arsenate, which is extremely toxic. Since that time, there are safer pressure used treatments are divided into three main types of preservatives: waterborne, creosol and oil-borne. These treatments are much less toxic than CCA.
