The higher cost of Byers Pipe originates in the old- 
fashioned puddling operation—slow and laborious, but the 
only known method of producing the highest quality of 
wrought iron. However, to the eye of the layman, genuine 
wrought iron looks much like the cheaper metal, steel. It 
has therefore been necessary for the Byers Company to de- 
vise distinguishing marks for their product, and for more than 
ten years the name Byers in raised letters, followed by two 
figures indicating year of manufacture, have been rolled 
into the metal and repeated each three or four feet on every 
ength of Byers pipe. 
Since early in 1925, an additional marking has been 
provided in the form of a colored stripe which winds around 
each piece of pipe from end to end. It is painted on by 
machinery in the course of the several inspections to which 
the pipe is subjected prior to shipment. This stripe is 
visible from any angle, at distances of 50 feet or more, and 
makes Byers Pipe, either black or galvanized, the most 
zasily identified of any pipe made. Byers nipples are also 
marked with the Byers name and the thickness; that is. 
whether standard or extra heavy weight. 
Among the notable modern structures in which many 
miles of Byers Pipe are in service, are the Woolworth Build: 
ing and the Pennsylvania Hotel, New York; Stevens Hotel, 
Chicago; William Penn Hotel, Pittsburgh; Southwestern 
Bell Telephone Building, St. Louis; Standard Oil Building, 
Baltimore; General Motors Building, Detroit; Dexter-Horton 
National Bank, Seattle; Seville-Biltmore Hotel, Havana; 
Marunouchi Building, Tokio, and many others equally well 
known. 
The Byers Company operates a blast furnace, puddle 
and rolling mills at Girard, Ohio, and puddle and pipe mills 
at Sixth and Bingham Streets, South Side, Pittsburgh. 
These two plants employ from 2,500 to 3,000 men. 
The principal business office of the company is at 235 
Water Street, Pittsburgh, with the general sales office in the 
Union Bank Building, Pittsburgh. Branch sales offices are 
maintained in Boston, New York, Rochester, Philadelphia, 
Pittsburgh, Cleveland, Chicago, St. Louis, Jacksonville, 
Birmingham, Houston, Tulsa and Los Angeles.
