Our History


PTC Alliance is a global leader in the manufacturing and distribution of Drawn-Over-Mandrel Tubing (DOM), Electrical Resistance Welded Tubing (ERW), Cold Drawn Seamless Tubing (CDS), Chrome Plated Tubing and Bar, and Tubular and Bar Machined Components.

Pittsburgh Tube Company, now PTC Alliance Corporation, was founded in 1924 when John P. Gangwisch purchased the small mill next door to his plant in Monaca, Pennsylvania. The distressed plant employed 60 people who manufactured buttweld pipe for iron beds. Mr. Gangwisch was convinced there was a ready market for iron beds and a bright future for a plant capable of fabricating a quality product. With capital improvements and a great sales effort, he believed the company would be successful.

Mr. Gangwisch presented his idea to four friends and business associates and together, these five men completed arrangements to take over the name, business, assets and liabilities of the Pittsburgh Tube Company.

The young company faced challenges early on as other pioneers in the field of welded steel tubing moved in on the iron bedstead tubing markets. Establishing flexibility it never lost, Pittsburgh Tube diligently sought new ways to make buttweld tubing and to find new markets for it. Over the years the company responded to competitive pressures by adding capital equipment when necessary and switching product lines when existing markets showed designs of decay. Expansion and planning has continued at a steady pace at PTC Alliance as the following steps in its growth will attest.
