What is CCA treated wood?

CCA-treated wood is used in marine facilities (pilings and structures), utility poles and cross arms, pilings for terrestrial and freshwater uses, commercial and agricultural construction (primarily foundations), and highway structures (such as bridge components, guardrails, and posts). CCA has a well-proven history of providing consistent long life to preserved wood products, both through over 50 years of laboratory and field testing as well as successful long-term use of products in challenging environments. Compared to non-wood products, benefits of wood products include lower density, ease of field modification, structural flexibility and durability, aesthetic appeal, and that wood is a renewable resource. CCA preservative adds benefits to wood including proven efficacy, long product life, and low cost. In addition, the treated product is clean, dry, non-slippery, and paintable, low in odor, and has a pleasing appearance.

What is the best chemical to use to fix wood?

The chromium acts as a chemical fixing agent and has little or no preserving properties; it helps the other chemicals to fix in the timber, binding them through chemical complexes to the wood's cellulose and lignin. The copper acts primarily to protect the wood against decay, fungi, and bacteria, while the arsenic is the main insecticidal component, providing protection from wood-attacking insects including termites and marine borers. It also improves the weather resistance of treated timber and may assist paint adherence in the long term.
