Business Description and Basis of Presentation [Text Block] | 1. Basis of Presentation: The accompanying consolidated financial statements have been prepared from the financial records of Olympic Steel, Inc. and its wholly-owned subsidiaries (collectively, Olympic or the Company), without audit and reflect all normal and recurring adjustments which are, in the opinion of management, necessary to fairly state the results of the interim periods covered by this report. Year-to-date results are not necessarily indicative of 2015 annual results and these financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. All significant intercompany transactions and balances have been eliminated in consolidation. Commencing with the first quarter of 2015, the flat products segment has been separated into two reportable segments; carbon flat products and specialty metals flat products. Prior year financial information has been recast to reflect the new segment reporting structure. The Company now operates in three reportable segments; carbon flat products, specialty metals flat products, and tubular and pipe products. 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 segments), including payroll expenses for certain personnel, expenses related to being a publicly traded entity such as board of directors expenses, audit expenses, and various other professional fees.
