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 global manufacturer and distributor of products for commercial, industrial and consumer markets. The Company is principally engaged in the following reportable segments with diverse products and market channels: Packaging, Energy, Aerospace & Defense, Engineered Components, Cequent Asia Pacific and Cequent Americas. The Company renamed its former "Cequent North America" reportable segment "Cequent Americas" effective in the third quarter of 2012 following an acquisition in Brazil to more appropriately reflect the expanding geography covered by the businesses in this reportable segment. See Note 18, "Segment Information," for further information on each of the Company's reportable segments.
