Quality = Meeting the Customer's Requirements

Above all else, Marmon/Keystone has always been committed to one concept: Quality.

The concept of quality is nothing new at Marmon/Keystone. In fact, for nearly a century we've proven our commitment to this concept. With every order, we give you the expertise of knowledgeable sales people, the selection of a full-range inventory containing over 9,500 sizes and grades of pipe and tubing, on-time deliveries, and our ongoing desire to meet and even exceed your expectations. This commitment to quality has made us a leader in the industry, serving over 30,000 customers worldwide. We have formalized the value-added service that has been our cornerstone all these years. We call it the Quality Improvement Process.

Our Quality Improvement Process

The Quality Improvement Process is a company-wide program that places the responsibility for quality in the hands of each and every one of our employees. All employees are encouraged to be proactive in their attitude toward quality, and this attitude has helped to shape the culture at Marmon/Keystone.
