 ClarkWestern Building Systems has been growing to meet the continued needs of our customers and we bring with us a long and respected history in the steel framing industry.  Clark Steel Framing, located in Middletown, Ohio, has been supplying steel framing products in the eastern United States since 1981.  Clark acquired its second location Delta Metal Products in Dallas, Texas in 1999.  Since that time we have opened a plant in Jefferson, Georgia and Ocala, Florida.  In 2004, Clark Steel Framing acquired Dale Industries which added five more locations to our business.  Most recently we have announced the opening of our newest facility in Rochelle, Illinois.  In 2006, we are completing the final integration of our sister company Western Metal Lath in Riverside, California.  Western has over fifty years of experiences providing quality lath, accessories and framing products to the western United States.  The combination of Clark and Western along with our acquisition of Dale Industries and our new plant openings gives us thirteen facilities nationally..
 ClarkWestern Building Systems has grown to what we are today so we can be closer to our customers while offering them the quality products and service they have come to expect from us over the years.  We continue to expand our product lines.  We now offer industry leading shaft wall framing products and industry preferred and recognized metal corner bead products.  Our engineering division, Clark Western Design, located in Georgia and in California, is quickly becoming the industries preferred resource for light gauge framing design and consultation.  ClarkWestern Building Systems works to bring its years of experience in the industry to our customers through knowledgeable salespeople and a management team committed to the success of our customers.  We recognize that our reputation rests upon quality products competitively delivered when they are needed. What's inside those walls, not only counts it is what we build our reputation on..But, this is only the beginning; we will continue to work to be our customers preferred supplier by adding additional plants and products so that we can be the industries first choice from framing to finishing, coast to coast.
