About Us Schroth Industries is a wood treatment plant and lumber yard located in Indiana, Pennsylvania. Walter Schroth III is the owner of the business, which has been in his family for three generations. Established in 1920 by the current owner's grandfather Walter A. Schroth Sr., the yard was originally a sawmill that supplied mine timbers to the booming mining industry at the time. In 1947, the business was passed on to Walter Schroth Jr. who continued sawmill operations and added to the business' scope by expanding it into a retail yard. In 1960 Walter Jr. exited the sawmill industry and in 1970 transformed the yard into a lumber treatment plant while also retaining some retail business through the sales of belts, pulleys, fasteners, and treated lumber.   In 1988, Walter Jr. transferred Schroth Industries to the current owner, Walter Schroth III. Walter Schroth has been involved in the business since his childhood, working for his father as a laborer in his teens and occasionally as a consultant while attending college. In 1992, due to the decline in the mining industry, Walter Schroth III diversified from mining timbers to a high end pressure treated wood product called UltraWood. He is in fact the first person to introduce UltraWood to Western Pennsylvania. Mr. Schroth has a Bachelor's Degree in Forest Management from Colorado State University and a Masters in Business Administration from the University of Idaho.
