Industries' Descriptions

@Metal Fabrication (+3.83% weekly)

The industry is involved in value-added processes including creation of metal structures like machines and parts by cutting, bending and assembling, using various raw materials. A fabrication shop often bids on a project/job, and then builds the product if awarded the contract. Robotics and automation are making their way into the industry apparently to fill in skills gap[s19] . RBC Bearings Incorporated, Timken Company and Valmont Industries, Inc. are some of the largest metal fabrication companies in the U.S.

@Steel (+1.65% weekly)

The steel industry includes manufacturers of steel and steel-related products. Companies use iron ore and scrap steel to produce steel. The industry also includes companies involved in mining and marketing of steel products. Along with serving some of the domestic markets, U.S. steel output has, over the years, been used by international economies as well. Competition from imported steel has also increased over time. The industry could be susceptible to business cycles, since the element is an important input in industrial production. Some of the globally-renowned steel behemoths include Nucor Corporation, Vale, and ArcelorMittal SA.
