All About Dun Transportation & Stringing Inc.

Over 100 Years of History

Dun Transportation & Stringing, Inc. is an irregular route Common and Contract Carrier, operating under Certificate of Convenience & Necessity MC 19416 & Subs issued by the Interstate Commerce Commission and regulated by the Surface Transportation Board (STB), a semi-independent agency within the United States Department of Transportation (DOT).

Allen Dunn organized Dunn Bros., in 1910. He began hauling all types of freight with teams and wagons. Dunn Bros. began hauling pipe in 1915 for Lone Star Gas Company. This work began in West Texas and terminated in the Dallas - Ft. Worth area. The beginning of the oil boom in 1917 influenced Allen Dunn to specialize in the service of transporting supplies for the oil fields and to haul pipe to the working locations in West Texas. Dunn Bros. was incorporated in 1950 in the state of Texas. Ernest C. Dunn was President and Ellis E. Dunn was Vice President. Ellis Dunn died in 1973. Ernest Dunn remained President and 100% owner until his death in August 1992. At that time Jewell Dunn became 100% owner and President. On July 31, 1998 Jewell Dunn sold her ownership to then Vice President Gene Johnson (nephew to the Dunn's). Mr. Johnson then became President and changed the name to Dun Transportation & Stringing, Inc.

Dun Transportation & Stringing, Inc. specializes in the shipping, unloading, racking, storing, hauling and stringing of pipe arriving by truck, rail, barges, and ships. When requested we assist in locating facilities for storing and racking of pipe. The company has hauled pipe from pipe mills, coating, or double jointing yards to temporary storage yards, or direct to the pipeline rights of way.

Dun Transportation & Stringing's experience in all phases of this work, sufficient specialized company owned equipment, and experienced personnel enable us to perform this specialized service in a good, safe workman like manner on schedule.
