The wood from the southern yellow pines typically has a density value between 50 and 55 lb/cu ft (0.80 and 0.88 g/cm 3) when pressure treated. Yellow pine grows across the South and Mid-Atlantic regions, from Texas to New Jersey. [7] [8]
Copper naphthenate sold for pressure treatment of wood is typically supplied as an 8% copper (as metal) concentrate for dilution to 0.5-1.5% copper (as metal) treating solutions.
