Some have never been used, others have been used so may have nails or screws, some cut. Have been sitting in a garage for a few years. Some better condition than others, see photos. Various sizes. I don't know anything about lumber but tags that are still intact on some say Alkaline copper quaternary and copper Azole. I believe theres over 50 pieces but again, some are cut and they range in width and lengths. The other reclaimed wood is a mixture in the last few photos, some are better condition than others. About 20 or so pieces. Contact me to make a time to take a look sometime next week. I can help load. $280 but offers are welcome. Buyer must take all. I also am going through a lot of reclaimed wood, indoor and outdoor trim and just random boards that need to be sold as well.
