To our Valued Customers
From our team to yours, we wish you a Thanksgiving filled with the spirit of gratitude that makes this time of year so special.
This month’s newsletter focuses on ACZA Chemonite® wood. If your customer asks for marine treated lumber, we suggest you quote ACZA treated wood. We have summarized below what you need to know about our marine treatment. Please contact our knowledgeable sales staff for a quote or additional information.
Since the 1940s, Chemonite® has been safely and successfully used in commercial and industrial applications. It is leach-resistant in water and ground. Chemonite® is the registered trade name for wood protected by ACZA, ammoniacal copper zinc arsenate, against termites and fungal decay. The treatment was originally developed, and remains today, as a waterborne system which can consistently meet recognized standards of penetration and retention in otherwise difficult-to-treat species such as coastal Douglas fir.
Chemonite® ACZA treated wood offers all of the appealing characteristics and beauty of real wood while enhancing its service life. Chemonite® ACZA preservative protects against the major causes of wood degradation: fungal decay, termites, and marine organisms. Studies indicate it also makes the wood resistant to carpenter ants, woodpeckers, and fire. It has protection both above ground and in ground contact, as well as in fresh and salt water.

May be stored, handled, and worked like untreated wood.
Recognized by model building codes.
Leach-resistant.
Can be painted or heavy-bodied stain.
Leaves surface free of chemical deposits.
Applications
Chemonite® ACZA treated wood is especially appropriate for industrial, utility, marine, and heavy construction applications, where coastal Douglas fir or other refractory species are used, or where longevity is a concern. Typical applications include:
Utility poles — distribution & transmission
Building poles
Foundation piling
Marine piling — fresh or salt water
Sawn timbers or supporting columns used for bridges, barns, homes, or other uses
Agricultural posts
Post frame construction
Highway construction
Railroad crossties
Water wood piping
Bridge framing
Docks
Sea coast walking paths
Guard rail
Glulams
Retaining walls
Use & Handling
Construction: Bracing with round timber piles rather than sawn timbers is recommended for marine construction below high tide. All untreated wood exposed by cutting or drilling should be adequately field treated. Avoid removing the outer shell of wood where treatment is heaviest and decay-resistance greatest. It is recommended that all structures be prefabricated before treatment; minimize problems by specifying framing and boring before treatment whenever possible. Worker Safety: Chemonite® ACZA treated wood can be stored, handled and worked like untreated wood. As with any wood, wear gloves to avoid splinters, wear eye protection and a dust mask when sawing, drilling and sanding. Wash hands before eating or smoking. Dispose of cut ends in a proper landfill. Treated wood should not be burned in open fires or in stoves, fireplaces or residential boilers. Treated wood from commercial or industrial use may be burned only in commercial or industrial incinerators or boilers in accordance with state and federal regulations.
Standards & Codes
ACZA is listed in the American Wood Protection Association (AWPA) Standard P22 (formerly P5) for Waterborne Preservatives. Wood treated with this preservative is accepted in AWPA Standard U1 for applications in Use Categories 1 through 5, that is, from interior applications to saltwater immersion. Within the requirements of the standards, ACZA can be used to treat numerous species of wood, however its ability to penetrate makes it particularly useful in the treatment of coastal Douglas fir, for which it is most commonly used.
AWPA standards are referenced in government specifications and model building codes for treated wood products.
Chemonite® ACZA treated wood is also listed in standards of the Canadian Standards Association (CSA O80).
