In 1950 H. C. Cobern started mining sand and iron ore tailings from local deposits in central Alabama to be used in the surrounding cement plants. This led to his sons purchasing trucks to make the local hauls. Gerald and Bill Cobern founded Woodstock Trucking Company in 1969. Specializing in the transportation of bulk material via pneumatic tanker, today WT is known for its dedication to customer service. In 1979 Gerald and Bill Cobern founded Filler Products Company, Inc, which specialized in mineral processing. Today Filler Products offers portable screening, trans-loading and bulk storage solutions in Central Alabama. The trans-loading facility is located on Norfolk Southern main line and has loading and unloading equipment with 3200ft of rail siding open both north and south. The Cobern brothers formed Alabama Pigments Company in 1993 with emphasis on natural red iron oxide. Through the years APC expanded its product offering and production capabilities. In 2007, Lee and Brent Cobern took over as Managing Partners and upgraded production and warehousing facilities and established a plan to take APC into the future. In 2009 APC opened its new plant for the production of natural black iron oxide, agricultural products and toll processing. 
 

2006, the planning phase of a complex that will house the new corporate offices, lab, warehouse and additional production facilities of APC is under way.
