Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | Basis of Presentation TriMas Corporation ("TriMas" or the "Company"), and its consolidated subsidiaries, is a diversified industrial manufacturer of products for customers in the consumer products, aerospace, industrial, petrochemical, refinery and oil and gas end markets. In the first quarter of 2018, TriMas realigned its reporting structure from four segments to three. While there were no changes to the Packaging and Aerospace reportable segments, the Company combined its previous Energy and Engineered Components reportable segments into a new reportable segment titled Specialty Products. This change was made in connection with recent realignment efforts, providing a more streamlined operating structure and to better leverage resources across the divisions in this segment. See Note 18, "Segment Information," for further information on each of the Company's reportable segments.
