Significant Accounting Policies [Text Block]	1. Summary of Significant Accounting Policies : Nature of Business The Company is a leading U.S. metals service center specializing in the processing and distribution of large volumes of carbon, coated, aluminum and stainless steel, flat-rolled coil, sheet and plate products and tubular and pipe products from facilities throughout the United States. The Company operates in three Principles of Consolidation and Basis of presentation The accompanying consolidated financial statements include the accounts of Olympic Steel, Inc. and its wholly-owned subsidiaries (collectively , the Company or Olympic), after elimination of intercompany accounts and transactions. Accounting Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Concentration Risks The Company is a major customer of flat-rolled coil and plate and tubular and pipe steel for many of its principal suppliers, but is not one 53%, 54% 51% three 2017, 2016 2015, The Company has a diversified customer and geographic base, which reduces the inherent risk and cyclicality of its business. The concentration of net sales to the Company’s top 20 27%, 29% 31% 2017, 2016 2015, 4%, 4% 6% 2017, 2016 2015, 51%, 51% 49% 2017, 2016 2015, Cash and Cash Equivalents Cash equivalents consist of short-term highly liquid investments, with a three Fair Market Value Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the liability in an orderly transaction between market participants on the measurement date. Valuation techniques must maximize the use of observable inputs and minimize the use of unobservable inputs. To measure fair value, the Company applies a fair value hierarchy that is based on three first two Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs other than Level 1 not Level 3 – Unobservable inputs that are supported by little or no Financial instruments, such as cash and cash equivalents, accounts receivable, accounts payable and the credit facility revolver, are stated at their carrying value, which is a reasonable estimate of fair value. The fair value of marketable securities is based on quoted market prices. Accounts Receivable The Company ’s allowance for doubtful accounts is maintained at a level considered appropriate based on historical experience and specific customer collection issues that the Company has identified. Estimations are based upon the application of a historical collection rate to the outstanding accounts receivable balance, which remains fairly level from year to year, and judgments about the probable effects of economic conditions on certain customers, which can fluctuate significantly from year to year. The Company cannot guarantee that the rate of future credit losses will be similar to past experience. The Company considers all available information when assessing the adequacy of the allowance for doubtful accounts each quarter. Inventories Inventories are stated at the lower of its cost or net realizable value with the adoption of A ccounting Standards Update (ASU) 2015 11 January 1, 2017.

If a quantitative fair value measurement is used, the fair value of each indefinite-lived intangible asset is compared to its carrying value and an impairment charge is recorded if the carrying value exceeds the fair value. The Company estimates the fair value of indefinite-lived intangible assets using a discounted cash flow methodology. Management ’s assumptions used for the calculations are based on historical results, projected financial information and recent economic events. Actual results could differ from these estimates under different assumptions or conditions which could adversely affect the reported value of intangible assets. The Company evaluates the recoverability of long-lived assets and the related estimated remaining lives whenever events or changes in circumstances indicate that the carrying value may not may not Income Taxes The Company records, as an offset to the estimated effect of temporary differences between the tax basis of assets and liabilities and the reported amounts in its consolidated balance sheets, the tax effect of operating loss and tax credit carryforwards.

Segment Reporting Disclosure [Text Block]	15. Segment Information: The Company follows the accounting guidance that requires the utilization of a “management approach” to define and report the financial results of operating segments. The management approach defines operating segments along the lines used by the Company ’s chief operating decision maker (CODM) to assess performance and make operating and resource allocation decisions. Our CODM evaluates performance and allocates resources based primarily on operating income. Our operating segments are based primarily on internal management reporting. The Company operates in three ’ assets and resources are shared by the carbon and specialty metals segments and both segments’ products are stored in the shared facilities and, in some locations, processed on shared equipment. As such, total assets and capital expenditures are reported in the aggregate for the flat products segments. Due to the shared assets and resources, certain of the flat products segment expenses are allocated between the carbon flat products segment and the specialty metals flat products segment based upon an established allocation methodology. Through its carbon flat products segment, the Company sells and distributes large volumes of processed carbon and coated flat-rolled sheet, coil and plate products. Through its specialty metals flat products segment, the Company sells and distributes processed aluminum and stainless flat-rolled sheet and coil products, flat bar products and fabricated parts. Through its tubular and pipe products segment, the Company distributes metal tubing, pipe, bar, valve and fittings and fabricates pressure parts supplied to various industrial markets. Corporate expenses are reported as a separate line item for segment reporting purposes. Corporate expenses include the unallocated expenses related to managing the entire Company (i.e., all three ’ expenses, audit expenses, and various other professional fees.

Fair Value Measurement, Policy [Policy Text Block]	Fair Market Value Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the liability in an orderly transaction between market participants on the measurement date. Valuation techniques must maximize the use of observable inputs and minimize the use of unobservable inputs. To measure fair value, the Company applies a fair value hierarchy that is based on three first two Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs other than Level 1 not Level 3 – Unobservable inputs that are supported by little or no Financial instruments, such as cash and cash equivalents, accounts receivable, accounts payable and the credit facility revolver, are stated at their carrying value, which is a reasonable estimate of fair value.

Trade and Other Accounts Receivable, Policy [Policy Text Block]	Accounts Receivable The Company ’s allowance for doubtful accounts is maintained at a level considered appropriate based on historical experience and specific customer collection issues that the Company has identified. Estimations are based upon the application of a historical collection rate to the outstanding accounts receivable balance, which remains fairly level from year to year, and judgments about the probable effects of economic conditions on certain customers, which can fluctuate significantly from year to year.

If a quantitative fair value measurement is used, the fair value of each indefinite-lived intangible asset is compared to its carrying value and an impairment charge is recorded if the carrying value exceeds the fair value. The Company estimates the fair value of indefinite-lived intangible assets using a discounted cash flow methodology. Management ’s assumptions used for the calculations are based on historical results, projected financial information and recent economic events. Actual results could differ from these estimates under different assumptions or conditions which could adversely affect the reported value of intangible assets.
