Segment Reporting [Abstract] |
Segment Information | Segment Information The Company's operating segments are identified on the basis of information that is reviewed by our chief operating decision maker, the Chief Executive Officer, to make decisions about resources to be allocated and assess its performance. The Company reports operating results in three principal business segments: Construction Products. The Construction Products segment primarily produces and sells natural and recycled aggregates, specialty materials, asphalt mix, and construction site support equipment, including trench shields and shoring products. Engineered Structures. The Engineered Structures segment primarily manufactures and sells steel and concrete structures for infrastructure businesses, including utility structures for electricity transmission and distribution, structural wind towers, traffic and lighting structures, and telecommunication structures. These products share similar manufacturing competencies and steel sourcing requirements and can be manufactured across our North American footprint. Transportation Products. The Transportation Products segment primarily manufactures and sells inland barges, fiberglass barge covers, winches, marine hardware, and other transportation and industrial equipment. In August 2024, the Company completed the sale of its steel components business, which manufactured and sold steel components for railcars. See Note 2 Acquisitions and Divestitures. The financial information for these segments is shown in the tables below. We operate principally in North America. Three Months Ended March 31, 2025
