Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company's Condensed Consolidated Financial Statements (Unaudited) as of June 30, 2026 and for the three-month and six-month periods ended June 30, 2026 and 2025 have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial reporting and therefore do not include all information and disclosures normally included in the annual Consolidated Financial Statements. The preparation of these Condensed Consolidated Financial Statements and accompanying notes in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ materially from these estimated amounts. In the opinion of the Company’s management, the Condensed Consolidated Financial Statements reflect all adjustments, which are normal and recurring in nature, and necessary for fair financial statement presentation. Results of operations for any interim period are not necessarily indicative of results for any future periods or for the year. The year-end Condensed Consolidated Balance Sheet data contained in this report was derived from audited financial statements, but does not include all disclosures required by GAAP. These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.
Reclassifications	Reclassifications During 2026, the Company reclassified the presentation of cash flows for the net change in book overdrafts from financing activities to operating activities in the Condensed Consolidated Statement of Cash Flows. Prior period amounts were reclassified to conform to the current period presentation, and in each period that amount is presented as a separate line within operating activities. The reclassification did not impact the Condensed Consolidated Balance Sheets or the Condensed Consolidated Statements of Comprehensive Income (Loss). Additionally, in the first six months of 2025, the Company presented its proceeds and repayments of borrowings under its revolving credit facility (“the Ryerson Credit Facility”) on a net basis as the borrowings had original maturities of three months or less and qualified for net presentation. Later in 2025 and in the first six months of 2026, the Company executed certain borrowings under the Ryerson Credit Facility with original maturities greater than three months and no longer qualified for net reporting. Thus the Company is presenting the borrowing activity on a gross basis in the statement of cash flows and has reclassified prior year presentation to conform with current year presentation for comparability.
Recent Accounting Pronouncements	Recently Issued Accounting Standards—Adopted No accounting pronouncements have been issued and adopted in 2026 that impact the Company's financial statements. Recently Issued Accounting Standards—Not Yet Adopted In November 2024, FASB issued ASU 2024-03, “Income Statement – Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” and in January 2025 issued an update through ASU 2025-01. The amendment requires disclosure in the notes to the financial statements of specified information about certain costs and expenses. The categories required to be disclosed under the amendment include; purchases of inventory, employee compensation, depreciation, and intangible asset amortization, as well as a qualitative description of the amount remaining in relevant expense captions that are not disaggregated quantitatively. Additionally, disclosure is required of the total amount of selling expenses and the entity's definition of selling expenses in the annual reporting periods only. This update is effective for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments may be applied on either a retrospective or prospective basis. The Company is assessing the impact of adoption, but does not expect this guidance to materially impact the consolidated financial statements, other than enhanced disclosures. In September 2025, FASB issued ASU 2025-06, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software”. The amendment changes certain aspects of the accounting and disclosure of software costs. Under the amendment, companies will no longer use the concept of "development stages" in determining the relevant software costs to be capitalized. Software costs will be capitalizable if management, implicitly or explicitly, authorizes and commits to funding a software project and the probable-to-complete threshold is met. This update is effective for annual periods beginning after December 15, 2027 and early adoption is permitted. These amendments can be applied prospectively to new software costs incurred as of the beginning of the adoption period for all projects, prospectively to new software costs incurred only for projects that meet the new capitalization requirements, or retrospectively by recasting comparative periods and recognizing a cumulative-effect adjustment to the opening balance of retained earnings of the first period presented. The Company is assessing the impact of adoption, but does not expect this guidance to materially impact the consolidated financial statements.

The Company's Condensed Consolidated Financial Statements (Unaudited) as of June 30, 2026 and for the three-month and six-month periods ended June 30, 2026 and 2025 have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial reporting and therefore do not include all information and disclosures normally included in the annual Consolidated Financial Statements. The preparation of these Condensed Consolidated Financial Statements and accompanying notes in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported.

Reclassifications

During 2026, the Company reclassified the presentation of cash flows for the net change in book overdrafts from financing activities to operating activities in the Condensed Consolidated Statement of Cash Flows. Prior period amounts were reclassified to conform to the current period presentation, and in each period that amount is presented as a separate line within operating activities. The reclassification did not impact the Condensed Consolidated Balance Sheets or the Condensed Consolidated Statements of Comprehensive Income (Loss).

Additionally, in the first six months of 2025, the Company presented its proceeds and repayments of borrowings under its revolving credit facility (“the Ryerson Credit Facility”) on a net basis as the borrowings had original maturities of three months or less and qualified for net presentation. Later in 2025 and in the first six months of 2026, the Company executed certain borrowings under the Ryerson Credit Facility with original maturities greater than three months and no longer qualified for net reporting. Thus the Company is presenting the borrowing activity on a gross basis in the statement of cash flows and has reclassified prior year presentation to conform with current year presentation for comparability.
