CCA treated wood has a considerably increased service life because of its effective fungicide and insecticide components. These protect against fungal decay, termites, and wood boring insects. Timber treated with CCA lasts for decades even in extreme environmental conditions. Its main uses include electrical and telephone posts, poles and heads for agricultural use, sawn timber, plywood, and structures in permanent contact with fresh or salt water. CCA is known as one of the most effective wood preservatives available.
