The Pennsylvania Supreme Court reversed the Commonwealth Court’s determination of the cost of steel products under the Steel Products Procurement Act. The Steel Act embodies “the policy of the Commonwealth of Pennsylvania that all public officers and agencies should, at all times, aid and promote the development of the steel industry of the United States to stimulate and improve the economic well-being of the Commonwealth and its people.” The Act requires that steel used in any public works project be at least 75% American steel. The Court held that 75% of the cost of the articles, materials, and supplies must be mined, produced, or manufactured in the United States.
