and general outdoor construction uses.

Pressure Treated offers many
benefits over other regular pressure
treated lumber:
• Top-quality lumber all made in the USA!
• Commercial treatments for structural use
• Lighter, more natural wood appearance
improves painting and staining qualities
• Approved for aluminum contact
• The treated wood process has been certified by
SCS as an Environmentally Preferable Product
• Building code compliant ICC-ES, ESR-2240,
third party inspected by SPIB
• National Green Building Standard Certified and
UL Greenguard Gold Certified
• Treated wood warranty programs (See warranty
for details)
Top-quality lumber 2x4 through 2x12 are either #2 Prime grade, #2 &
Better/Appearance grade or #1 grade. Both #2 grades have all the
characteristics, including knot size, of regular #2 grades but are selected
for 4 square edges (very light to no-wane or bark). #2 Prime Grade has
a maximum hole size of ¼”. #1 grade can have more wane (or bark)
and a little larger hole than the #2 Prime or Appearance grades but has
smaller knots, more clear wood, is stronger than #2, and will span
further than #2 grade.
1x4 through 1x10 boards are #2 & Better/Appearance grade,
hand-selected for smaller knots and light to no wane. 1x10 boards are
double grooved on the back side to relieve pressure, reduces cupping,
twisting, and warping of this wider board. This is not found at other
retailers.
5/4x6 decking is wane-free and 15% thicker than others standard
decking and comes with a first season built-in water repellent.
More preservative than regular above ground pressure treated All
2x4 through 2x12 - 18’ and 20’ lengths are treated to .15 pounds of
preservative per cubic foot of wood for ground contact applications,
over twice the preservative of regular above ground treatment!
Commercial grade treatments for critical structural use. All 4x4
and 4x6 timbers 12’ and longer and all 6x6 and larger timbers are
treated to critical structural treatment (.23 pounds of preservative per
cubic foot of wood) vs. most others with “ground contact” (.15 pounds
of preservative per cubic foot of wood). Many municipal and state
building codes require this critical structural treatment when
timbers in a structural use are put into the ground. Examples
include, but are not limited to, structures attached to a home
(decks and porches) and structures that support a roof (pavilions,
pergolas or gazebos).
Lighter, More Natural Color Not only does a lighter color allow
for the natural appearance of wood to show through, but it also
improves staining and painting qualities.
Approved for Aluminum Contact AC2
®
pressure treated
products are approved for aluminum contact while other
treatments available today are not because of their corrosiveness.
Corrosive treatments, such as, ACQ are not only bad for
aluminum but can also prematurely corrode other metal fasteners.
This can result in premature failure, plus more expensive
fasteners must be used for ACQ.
Building Code Compliant ICC-ES, ESR-12240. AC2® pressure
treated products meet or exceed the stringent rules set forth by the
ICC. In addition all AC2® is certified approved by the National
Green Building Standards, UL Greenguard Gold, SCS, and third
party certified by the Southern Pine Inspection Bureau (SPIB) for
quality assurance.
