Bull Moose Tube offers the widest range of Hard Metric Hollow Structural Sections (HSS) among the North American tube producers. Our unique direct form process provides us with the most frequent rolling cycles in the industry. In turn, these fast cycle times allow us to provide a large variety with minimal tooling time and cost. In addition to its ISO9002 certification, Bull Moose Tube holds the only Übereinstimmungsnachweis (Ü-Zeichen) certification among the North American Hard Metric HSS producers. "Ü-Zeichen" certification is required on all products used for construction within Germany to assure consistent, high-quality products designed to uniform standards.
