PRESSURE-TREATED WOOD By William G. Krizan, McGraw-Hill Construction | ENR
Industry Sounds Warnings Over Corrosive Effect on Steel
Health concerns that started over the use of wood treated with chromated copper arsenate (CCA) on playgrounds has triggered a revolution in wood treatment. As of Jan. 1, CCA-treated wood only will be allowed for certain industrial uses. In its place are no fewer than four substitute treatments that use other chemicals. But some wood experts now are concerned that builders, specifiers and purchasers are unaware of the higher corrosive properties of some treated wood when selecting metal connectors and fasteners.------------------------------------------- posted 7:04 AM :: reference link ::
