Accounting Policies [Abstract]
Background and Summary of Significant Accounting Policies	1. BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business - The Company is managed based primarily on the geographies in which it operates and reports results of operations in two reportable segments. The reportable segments are Domestic and International. Historically, sales of the Company’s products have been higher in the first and second quarters of each fiscal year due to favorable weather and longer daylight conditions accelerating construction activity during these periods. Seasonal variations in operating results may also be impacted by inclement weather conditions, such as cold or wet weather, which can delay projects. Basis of Presentation - 10-K/A 10-K/A”). 10-K/A.

Fair Value Disclosures [Abstract]
Fair Value Measurement	3. FAIR VALUE MEASUREMENT The fair value measurements and disclosure principles of ASC 820 - Fair Value Measurements and Disclosures define fair value, establish a framework for measuring fair value and provide disclosure requirements about fair value measurements. These principles define a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity has the ability to access as of the measurement date. Level 2 — Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 — Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. When applying fair value principles in the valuation of assets and liabilities, the Company maximizes the use of quoted market prices and minimizes the use of unobservable inputs. When active market quotes are not available for financial assets and liabilities, the Company uses industry standard valuation models. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including credit risk, interest rate curves, foreign currency rates and forward and spot prices for currencies. In circumstances where market-based observable inputs are not available, management judgment is used to develop assumptions to estimate fair value. Generally, the fair value of Level 3 instruments is estimated as the net present value of expected future cash flows based on internal and external inputs.

The accelerated depreciation was included in Loss (gain) on disposal of assets and costs from exit and disposal activities. One facility closed in the third quarter of fiscal 2017, and ADS reduced production at the other facility in the fourth quarter of fiscal 2017. A third facility, which is part of the Company’s South American Joint Venture, is also planning on reduced production.

Related Party Transactions [Abstract]
Related Party Transactions	4. RELATED PARTY TRANSACTIONS ADS Mexicana - Occasionally, ADS and ADS Mexicana jointly enter into agreements for pipe sales with related parties. There were no such sales in either the three and nine months ended December 31, 2016 or 2015. However, outstanding receivables related to such sales from prior periods were $0.3 million as of both December 31, 2016 and March 31, 2016. In April 2015, ADS Mexicana borrowed $3.0 million under a revolving credit facility arrangement with Scotia Bank and loaned that amount to ADS. The loan was repaid in May 2015. In June 2015, ADS Mexicana borrowed $3.9 million under the Scotia Bank credit facility and loaned it to an entity owned by a Grupo Altima shareholder, and such loan was repaid in July 2015. The applicable interest rates for the loans were 2.15% and 4.81%, respectively. ADS does not guarantee the borrowings from this facility, and therefore does not anticipate any required contributions related to the balance of this credit facility. The Company is the guarantor of 100% of a second credit facility for ADS Mexicana, and the Company’s maximum potential payment under this guarantee is $12.0 million. There were no borrowings outstanding under this facility as of December 31, 2016 or March 31, 2016. South American Joint Venture - ADS and the South American Joint Venture have shared services arrangements in order to execute the joint venture services. Included within these arrangements are the lease of an office and plant location used to conduct business and operating expenses related to these leased facilities. In addition, the South American Joint Venture has entered into agreements for pipe sales with ADS and its other related parties, which totaled $0.2 million and $0.7 million for the three and nine months ended December 31, 2016, respectively, and $0.2 million and $1.1 million for the three and nine months ended December 31, 2015, respectively. In December 2016, a fire destroyed approximately $1.1 million of finished goods inventory at one of the facilities of the Company’s South American Joint Venture. The Company’s portion of the inventory loss was recorded in Equity in net loss of unconsolidated affiliates. While the Company expects that the loss is recoverable through insurance proceeds, the amount of the recovery is not currently determinable. Once the amount of recovery is determinable, the Company’s portion will be recorded in Equity in net loss of unconsolidated affiliates. BaySaver - ADS and BaySaver have entered into shared services arrangements in order to execute the joint venture services. Included within these arrangements are the lease of a plant and adjacent yard used to conduct business and operating expenses related to the leased facility. Occasionally, ADS and BaySaver jointly enter into agreements for sales of pipe and Allied Products with their related parties, which were immaterial for the periods presented.

Commitments and Contingencies	7. COMMITMENTS AND CONTINGENCIES Purchase Commitments- Litigation and Other Proceedings- No. 1:15-cv-05955-KPF), 10b-5 On August 12, 2015, the SEC Division of Enforcement (“Enforcement Division”) informed the Company that it was conducting an informal inquiry with respect to the Company. As part of this inquiry, the Enforcement Division requested the voluntary production of certain documents generally related to the Company’s accounting practices. Subsequent to the initial voluntary production request, the Company received document subpoenas from the Enforcement Division pursuant to a formal order of investigation. The Company has from the outset cooperated with the Enforcement Division’s investigation and intends to continue to do so. While it is reasonably possible that this investigation ultimately could be resolved unfavorably to the Company, the Company is currently unable to estimate the range of possible losses, but they could be material. The Company is involved from time to time in various legal proceedings that arise in the ordinary course of its business, including but not limited to commercial disputes, environmental matters, employee related claims, intellectual property disputes and litigation in connection with transactions including acquisitions and divestitures. The Company believes that such litigation, claims and administrative proceedings will not have a material adverse impact on its financial position or its results of operations. The Company records a liability when a loss is considered probable and the amount can be reasonably estimated. In management’s opinion, none of these proceedings are material in relation to the Company’s consolidated operations, cash flows, or financial position, and the Company has adequate accrued liabilities to cover its estimated probable loss exposure.

These principles define a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity has the ability to access as of the measurement date. Level 2 — Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 — Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
