Companies engaged in the steel fabrication and erection industry prepare detailed shop drawings, fabricate and erect structural steel and steel plate weldments, and perform related engineering services for the construction of various facilities. The primary customers for these services include private developers, general contractors, engineering firms and governmental agencies involved in a variety of large-scale construction projects. Historically, these customers have relied on multiple subcontractors to perform various services to complete a single project, primarily because few companies in this industry offer fully integrated design-build, engineering, detailing, fabrication and erection services. Schuff Steel, one of our subsidiaries, is one of the few fully integrated companies in the industry, although our Addison, Bannister and Six subsidiaries offer erection capabilities through subcontractors.
