PABCO Gypsum is one of the leading manufacturers of wallboard in the United States. A division of PABCO Building Products LLC, PABCO Gypsum is one of the companies that make up Pacific Coast Building Products, a privately held supplier of building products and services. Pacific Coast Building Products has more than 3,000 employees and sales in excess of $900 million annually. PABCO Gypsum began manufacturing and shipping from its Newark, Calif., facility in 1972. Five years later, PABCO expanded with the acquisition of a gypsum board plant and gypsum quarry north of Las Vegas. In 1998 and 2005, the Las Vegas plant was expanded and modernized and now these two facilities supply over 1.65 billion annual square feet of gypsum board. PABCO also owns and operates a gypsum face and back paper mill in Vernon, Calif. That mill was acquired in 1984 and modernized and expanded in concert with PABCO s wallboard production increases.
