Pressure Treated Pine

The Pressure Treated Pine that we supply is without a doubt the highest grade PTP that is available today. What we sell is a #1 grade DSS (Dense Select Structural) which is at the top of the list in the Southern Pine Inspection Bureau Standard Grading Rules for Southern Pine Lumber. This creates a pine pergola of exceptional strength and durability.

Here are the major advantages of Pressure Treated Pine Pergolas:

#1 DSS (Dense Select Structural) .40 ACQ (Alkaline Copper Quat)

• Cut from a slow grown tree
• Ground contact lumber (meaning that every component of the kit, even the 2×2 top slats, is made with lumber that is designed to be able to be buried in the ground for the life of the lumber without rotting)
• Tighter rings
• Twice the density
• Twice the strength, meaning you can make longer beam and rafter spans between support posts without sagging
• Very few knots
• Very low amount of edge wain. Usually none.
• Not as prone to warping and cracking due to it being cut from a slow grown tree
• This is marine grade lumber for use above the water line
• Safe pressure treatment (does not contain arsenic)
• Insect resistant
