Triangle Suspension Systems, Inc. - A Marmon/Berkshire Hathaway Company

Since 1919, the TRIANGLE name has been synonymous with steel leaf springs. Originally, the company was located in the “Golden Triangle” section of Pittsburgh, and in 1927, the base of TRIANGLE’s operations moved to DuBois, PA. TRIANGLE’s market share increased through steady organic growth over the years. A series of strategic acquisitions has firmly positioned TRIANGLE as a leader in undercarriage products for heavy-, medium-, and light-duty trucks and trailers in the North American market. Today, TRIANGLE operates as a subsidiary of Webb Wheel Products, strengthening its commitment to quality, innovation, and customer support.
