 Redwood Empire carries a
selection of treated lumber. During the
pressure-treated process, the lumber is put in a
cylinder that is filled with a liquid
preservative. The cylinder is locked and the
pressure is raised inside the cylinder forcing
the preservative into the wood. The result is a
stronger, more disease or rot resistant piece of
lumber for your project.
Pressure
Treated (PT)
Redwood Empire carries a wide
variety of dimensions of Doug Fir and Hem Fir
pressure-treated. Contact one
of our sales representatives to get your quote.
When working with Pressure-treated lumber,
always use gloves and clean up the sawdust and
debris when finished. Do not use
pressure-treated lumber in areas that will come
in contact with food preparation or for the
storage of food. We offer several choices in the
types of preservative used in pressure-treated
lumber:
ACQ:
This is an arsenic free preservative. ACQ
lumber combines tan Alkaline, Quat and 100%
recycled copper to create an environmentally
advanced wood preservative. This is a new
preservative that is considered safe for
playground equipment and garden areas. Available
in green or cedartone color. CA :
Wolman® E preservative (CA) is a preservative
that contains copper and azole. The fact that it is
arsenic free, makes it easier on the
environment. It provides against decay and
termites. This lumber is great for patio,
walkways and decks. Available in green or
cedartone color. ACZA:
Chemonite® (ACZA) treated wood contains arsenic
as an active ingredient to fight insect attack
and decay on Doug Fir. This is used when
strength is a major consideration. From 2x4 to
6x6, we stock it. Call us with your dimensions.
Fire-Retardant
 is processed for use above the ground. Tests
have shown that when this lumber is used, the
flame spread is slower and smoke developing is
less dense. The structure also retains its
strength longer during a fire. This also has
some resistance to decay and termites when used
above ground.
