Segment Reporting [Abstract] |
Segment Information | Segment Information 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, and construction site support equipment, including trench shields and shoring products. Engineered Structures. The Engineered Structures segment primarily manufactures and sells steel structures for infrastructure businesses, including utility structures for electricity transmission and distribution, structural wind towers, traffic structures, and telecommunication structures. These products share similar manufacturing competencies and steel sourcing requirements and can be manufactured across our North American footprint. The segment also manufactures concrete utility structures. Historically, the segment also manufactured storage and distribution tanks. In October 2022, the Company completed the divestiture of its storage tanks business. See Note 2 Acquisitions and Divestitures. Transportation Products. The Transportation Products segment primarily manufactures and sells inland barges, fiberglass barge covers, winches, marine hardware, and steel components for railcars and other transportation and industrial equipment. The financial information for these segments is shown in the tables below. We operate principally in North America.
