Wolmanized® Heavy Duty Pressure-Treated Wood
Protected by CCA preservative
CCA has been used to pressure treat lumber since the 1940s. Since the 1970s, the majority of the wood used in outdoor residential settings has been CCA-treated wood. Pressure treated wood containing CCA is no longer being sold for use in most residential settings, including decks and playsets
. Primary uses for which South Houston Lumber sells CCA-treated wood include pole barns/sheds and laminating columns.
Chromated Copper Arsenate (CCA) is a chemical wood preservative containing chromium, copper and arsenic. CCA is used in pressure treated wood to protect wood from rotting due to insects and microbial agents. In the CCA treatment, copper is the primary fungicide, arsenic is a secondary fungicide and an insecticide, and chromium is a fixative which also provides ultraviolet (UV) light resistance. Recognized for the greenish tint it imparts to timber, CCA is a preservative that was extremely common for many decades.
In the pressure treatment process, an aqueous solution of CCA is applied using a vacuum and pressure cycle, and the treated wood is then stacked to dry. During the process, the mixture of oxides reacts to form insoluble compounds,
providing long service life with minimal leaching.
Wolmanized® Outdoor® wood
Protected by MCA preservative
Micronized Copper Azole (MCA) is the latest generation wood preservative systems. It provides effective resistance against termite damage and fungal decay and is suited for long-term performance in both indoor and outdoor applications. Common uses include decks, playground equipment, picnic tables, etc.
The preservative consists of very small (micron-sized) particles of solid copper, suspended in a liquid carrier, and pressure-injected into wood with azoles as co-biocides for defense against copper-tolerant fungi. By grinding the copper into fine particles, there is no need to dissolve the copper, as is done in traditional copper-based preservatives. The use of solid copper particles, rather than dissolved copper, results in a number of improved characteristics of the treated wood. This wood is a more natural color, among other properties. MCA treated lumber is clean, odorless, and non-irritating to humans, animals and plants. Proper care must still be exercised in handling this wood, as with any building material, during construction and disposal.
The Wolmanized name has long been associated with top-notch performance and industry-leading advancements.
