an array of investments<\/a> that would ramp up steel production in the United States as well as create American jobs.<\/p>\nThe just-bought property is at multiple addresses in eastern Contra Costa County \u2014 including 900 Loveridge Road, 750, 900, and 935 East Third St., 3122 Columbia St., and 2907 Antioch-Pittsburg Highway, all in Pittsburg \u2014 county documents show.<\/p>\n
U.S. Steel Property Holdings took ownership of the 11 parcels that make up the shuttered steel factory\u2019s sites through a quitclaim deed.<\/p>\n
The Pittsburg mill was formerly a 50-50 venture between Pennsylvania-based U.S. Steel and South Korea-based steel company POSCO.<\/p>\n
In 2020, U.S. Steel bought out the 50% interest that POSCO-California Corp. had owned in the East Bay factory. The plant produced cold-rolled sheets, galvanized sheets, tinplate and tin-free steel.<\/p>\n
U.S. Steel \u201cindefinitely idled\u201d steel production at the UPI plant in Pittsburg in December 2023, according to a post on the company\u2019s website.<\/p>\n
In the wake of the Nippon Steel purchase, however, U.S. Steel has announced plans for a big upgrade at an Alabama plant, a restart of a blast furnace at an Illinois plant, and a revamp of a blast furnace at an Indiana plant.<\/p>\n
The shutdown of the UPI steel mill in the East Bay erased 474 jobs at the plant. At the time it suspended operations, the factory was the only West Coast producer of tin plates for the canning industry, along with other products.<\/p>\n
U.S. Steel\u2019s plans for the idled plant weren\u2019t immediately clear; the company did not immediately respond to a request for comment.<\/p>\n","protected":false},"excerpt":{"rendered":"PITTSBURG \u2014 A United States Steel Corp. unit has bought the Pittsburg property where a steel mill had…\n","protected":false},"author":2,"featured_media":62270,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[380],"tags":[1167,78,1168,1173,1161,34933,1162,34934,34935,119,34931,602,1163,1174,154,21558,34932,442,1164],"class_list":["post-62269","post","type-post","status-publish","format-standard","has-post-thumbnail","category-posco","tag-bay-area","tag-business","tag-california","tag-california-news","tag-commercial-real-estate","tag-contra-costa-county","tag-development","tag-east-bay","tag-east-contra-costa","tag-economy","tag-editors-picks","tag-jobs","tag-keywee","tag-latest-headlines","tag-news","tag-pittsburg","tag-pm-report","tag-posco","tag-real-estate"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/62269","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/comments?post=62269"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/62269\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media\/62270"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media?parent=62269"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/categories?post=62269"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/tags?post=62269"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
