Segment Reporting [Abstract]

BUSINESS SEGMENTS

BUSINESS SEGMENTS

In the fourth quarter of 2017, the Company's management structure and reporting was changed to reflect management's expectations of the future growth of certain product lines and to take into consideration the expected divestiture of the grinding media business which historically was reported in the Energy and Mining segment. Grinding media will be reported in "Other" pending the completion of its divestiture. The access systems applications product line is now part of the Engineered Support Structures ("ESS") segment and the offshore and other complex structures product line is now part of the Utility segment. The segment financial information have been accordingly reclassified in this report to reflect these changes, for all periods presented.

The Company has four reportable segments based on its management structure. Each segment is global in nature with a manager responsible for segment operational performance and the allocation of capital within the segment. Net corporate expense is net of certain service‑related expenses that are allocated to business units generally on the basis of employee headcounts.

Reportable segments are as follows:

ENGINEERED SUPPORT STRUCTURES: This segment consists of the manufacture and distribution of engineered metal and composite structures and components for lighting, traffic, and wireless communication markets, engineered access systems, and highway safety products;

UTILITY SUPPORT STRUCTURES: This segment consists of the manufacture of engineered steel and concrete structures for the global utility transmission, distribution, and generation applications and on and offshore and other complex steel structures used in energy generation and distribution outside the United States, and inspection services;

COATINGS: This segment consists of galvanizing, anodizing and powder coating services; and

IRRIGATION: This segment consists of the manufacture of agricultural irrigation equipment, parts, services and tubular products and technology for precision agriculture.

In addition to these four reportable segments, the Company had other businesses and activities that individually are not more than 10% of consolidated sales, operating income or assets. This includes the manufacture of forged steel grinding media for the mining industry and is reported in the "Other" category.

The Company evaluates the performance of its business segments based upon operating income and invested capital. The Company does not allocate LIFO expense, interest expense, non-operating income and deductions, or income taxes to its business segments.
