Our 90 x 90mm posts are produced from 'No. 1 Select Construction' grade Southern Yellow Pine. This grade is recommended for construction where high strength, stiffness and good appearance is of importance. Small well spaced knots are allowed.
These posts are treated for 'in- ground' use and will last a minimum of 25 years. This is an incredible life expectancy for a fence post and is due to the fact that Southern Yellow Pine reacts exceptionally well to being pressure treated. The unique cellular structure of this species permits deep, uniform penetration of wood preservatives, unlike many other timbers that only allow limited penetration of the preservative. This makes treating the exposed ends of sawn timber unnecessary and gives the timber a long service life..
Sustainable forestry practices ensure that the supply of Southern Yellow Pine will be maintained for future generations. Trees cover about a third of the entire United States and are more plentiful now than they were 75 years ago. In addition, over four million trees are planted every day in America and more are grown every year than are harvested or lost to disease, insects and fire.
