AWPA's Standards are universally specified for wood preservation in the USA and are recognized worldwide.

Staff experts develop state-of-the-art engineering data, technology, and standards for wood products to assure their safe and efficient design, as well as provide information on wood design, green building, and environmental regulations. AWC also advocates for balanced government policies that affect wood products.
