Presentation The accompanying condensed consolidated balance sheet as of February 28, 2019 , which was derived from audited financial statements, and the unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete consolidated financial statements. These financial statements should be read in conjunction with the audited financial statements and related notes for the fiscal year ended February 28, 2019 , included in the Company’s Annual Report on Form 10-K covering such period. Our fiscal year ends on the last day of February and is identified as the fiscal year for the calendar year in which it ends. For example, the fiscal year ending February 29, 2020 is referred to as fiscal 2020. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, which are necessary to present fairly the financial position of the Company as of November 30, 2019 , the results of its operations for the three and nine months ended November 30, 2019 and 2018 , and cash flows for the nine months ended November 30, 2019 and 2018 . These interim results are not necessarily indicative of results for a full year. Reclassifications Certain prior fiscal year balances in the condensed consolidated statements of cash flows have been reclassified to conform to the current fiscal year presentation. In particular, payments for employee taxes related to net share settlement of equity awards and proceeds from the issuance of shares under the Company's Employee Stock Purchase Plan have been reclassified from operating activities to financing activities. Such reclassifications were not material. Recently Issued Accounting Pronouncements In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instrument s (“ASU 2016-13”), which modifies the measurement of expected credit losses of certain financial instruments, including the Company's accounts receivable and contract assets. The Company will adopt ASU 2016-13 in the first quarter of its fiscal 2021 utilizing the modified retrospective transition method. Based on the composition of the Company’s accounts receivable and contract assets, current market conditions, and historical credit loss activity, the adoption of ASU 2016-13 is not expected to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract ("ASU 2018-15"), which aligns the accounting for implementation costs incurred in a hosting arrangement that is a service contract with the accounting for implementation costs incurred to develop or obtain internal-use software, in order to determine the applicable costs to capitalize and the applicable costs to expense as incurred. The Company will adopt ASU 2018-15 in the first quarter of its fiscal 2021. The standard can be applied either prospectively to implementation costs incurred after the date of adoption or retrospectively to all arrangements. The Company intends to adopt ASU 2018-15 using the prospective approach and the adoption is not expected to have a material impact on its consolidated financial statements.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes The Company’s quarterly provision for income taxes is measured using an estimated annual effective tax rate, adjusted for discrete items that occur within the quarter. The following table presents income tax expense and the effective tax rate for the periods (in thousands, except percentages): Three Months Ended November 30, Nine Months Ended November 30, 2019 2018 2019 2018 Income tax expense $ 8,835 $ 3,342 $ 16,932 $ 10,511 Effective tax rate 28.6 % 17.8 % 22.3 % 19.9 % The calculation of the Company's tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across the Company's global operations. Generally accepted accounting principles in the United States of America ("GAAP") states that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. The Company may (1) record unrecognized tax benefits as liabilities in accordance with GAAP and (2) adjust these liabilities when the Company's judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the Company's current estimate of the unrecognized tax benefit liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information is available. A reconciliation of the beginning and ending balance of total unrecognized tax benefits for the nine months ended November 30, 2019 is as follows (in thousands): November 30, 2019 Balance at beginning of period $ — Tax positions taken in current period: Gross increases 3,899 Lapse of statute of limitations $ (1,548 ) Balance at end of period $ 2,351 After a review of its deferred tax balances as of August 31, 2019, the Company recorded unrecognized tax benefits of $3.9 million within other long-term liabilities related to the amortization of goodwill and certain book reserve balances incorrectly deducted in prior years. The amortization relates to the Company deducting more expense than permitted for tax purposes. The total unrecognized tax benefits, if recognized, would reduce income tax expense and the Company’s effective tax rate. During the three months ended November 30, 2019, the Company released $1.5 million of this unrecognized tax benefit upon the lapse of the applicable statute of limitations. Additionally, as a part of this review of its deferred tax balances, the Company corrected other current and deferred income tax expense amounts related to prior periods which netted to $1.4 million and were recorded as a tax benefit in the nine months ended November 30, 2019. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. Accrued interested and penalties included in the non-current income tax payable related to penalties and interest for prior periods was $1.1 million as of November 30, 2019. Certain prior year tax returns are currently being examined by taxing authorities in the United States. The Company believes that it has provided adequate reserves for its income tax uncertainties in all open tax years. As the outcome of the tax audits cannot be predicted with certainty, if any issues addressed in the Company's tax audits are resolved in a manner inconsistent with management's expectations, the Company could adjust its provision for income taxes in the future. The Company has operations and taxable presence in multiple jurisdictions in the U.S. and outside of the U.S. in Canada, the Netherlands, China, Poland and Brazil. The tax positions of the Company and its subsidiaries are subject to income tax audits by multiple tax jurisdictions around the world. The Company currently considers U.S. federal and state and Canada, to be significant tax jurisdictions. The Company’s U.S. federal and state tax returns since February 28, 2017 remain open to examination. With some exceptions, tax years prior to fiscal 2017 in jurisdictions outside of U.S. are generally closed. The statute of limitations for fiscal year end 2017 will expire in December 2020. The Company anticipates it is reasonably possible that a decrease of unrecognized tax benefits up to approximately $1.1 million may occur in the next 12 months, as the applicable statutes of limitations lapse.

Stock-based Compensation

Stock-based Compensation	9 Months Ended
	Nov. 30, 2019
Share-based Compensation [Abstract]
Stock-based Compensation	Share-based Compensation The Company has two share-based compensation plans, the 2014 Long Term Incentive Plan (the "2014 Plan") and the Amended and Restated 2005 Long Term Incentive Plan (the “2005 Plan”). The 2014 Plan provides for broad-based equity grants to employees, including executive officers, and members of the board of directors and permits the granting of restricted shares, restricted stock units, performance awards, stock appreciation rights and other stock-based awards. The maximum number of shares that may be issued under the 2014 Plan is 1.5 million shares and, as of November 30, 2019 , the Company had approximately 1.3 million shares reserved for future issuance under this plan. The 2005 Plan permitted the granting of stock appreciation rights and other equity-based awards to certain employees. This plan was terminated upon the effective date of the 2014 Plan and no future grants may be made under the 2005 Plan. There were stock appreciation rights granted under the 2005 Plan prior to its termination that remain outstanding, and if exercised, such awards will be settled from the balance of shares available for issuance under the 2005 Plan. As of November 30, 2019 , there were 0.1 million shares available for issuance under the 2005 Plan. The 2005 Plan will be formally retired when all remaining outstanding stock appreciation rights are exercised, forfeited or expire. All outstanding stock appreciation rights will expire on or before March 1, 2021. Restricted Stock Unit Awards Restricted stock unit ("RSU") awards are valued at the market price of our common stock on the grant date. Awards generally vest ratably over a period of three years but these awards may vest earlier in accordance with the Plan’s accelerated vesting provisions. RSU awards have dividend equivalent rights (“DERs”), which entitle holders of RSUs to the same dividend value per share as holders of common stock. DERs are subject to the same vesting and other terms and conditions as the corresponding unvested RSUs. DERs are accumulated and paid when the underlying shares vest. A summary of the Company’s non-vested restricted stock unit award activity (including DERs) for the nine month period ended November 30, 2019 is as follows: Restricted Stock Units Weighted Average Grant Date Fair Value Per Share Non-vested balance as of February 28, 2019 146,532 $ 48.93 Granted 87,092 43.77 Vested (81,069 ) 54.73 Forfeited (5,893 ) 45.76 Non-vested balance as of November 30, 2019 146,662 $ 44.46 Performance Share Unit Awards The Company grants performance share unit ("PSU") awards to certain employees, which also include DERs as described above. These PSU awards have a three year performance cycle and will vest and become issuable, if at all, on the third anniversary of the award date. The PSU awards are subject to the Company’s degree of achievement of a target annual average adjusted return on assets during these three year periods and, in certain circumstances, vesting is based on the relative performance of a predetermined group of peer companies. In addition, these PSU awards may have vesting conditions or certain vesting multipliers, which are based on the Company’s total shareholder return during such three years in comparison to a defined specific industry peer group. The Company estimates the fair value of PSU awards with performance and service conditions using the value of the Company's common stock on the date of grant. The Company estimates the fair value of PSU awards with market conditions using a Monte Carlo simulation model on the date of grant. A summary of the Company’ non-vested performance share unit award activity (including DERs) for the nine month period ended November 30, 2019 is as follows: Performance Weighted Average Grant Date Fair Value Per Share Non-vested balance as of February 28, 2019 83,125 $ 50.33 Granted 49,228 46.19 Vested — — Forfeited (22,417 ) 57.47 Non-vested balance as of November 30, 2019 109,936 $ 47.55 The PSU awards in the table above are presented at the face value of the respective grants. However, the number of PSU awards that may ultimately vest can vary in a range 0% to 250% of the face amount of such awards depending on the outcome of the performance or market vesting conditions. Stock Appreciation Rights Stock appreciation rights ('SARs") are granted with an exercise price equal to the market value of our common stock on the date of grant. These awards generally have a contractual term of 7 years and vest ratably over a period of three years although some may vest immediately on issuance. These awards are valued using the Black-Scholes option-pricing model. A summary of the Company’s SARs activity for the nine month period ended November 30, 2019 is as follows: SARs Weighted Average Exercise Price Outstanding as of February 28, 2019 98,184 $ 44.46 Granted — — Exercised (2,965 ) 44.58 Forfeited — — Outstanding as of November 30, 2019 95,219 $ 44.58 Exercisable as of November 30, 2019 95,219 $ 44.58 The average remaining contractual term for SARs outstanding and SARs that were exercisable as of November 30, 2019 was 1.11 years, with an aggregate intrinsic value of less than $0.1 million . Employee Stock Purchase Plan The Company also has an Employee Stock Purchase Plan ("ESPP"), which allows employees of the Company to purchase common stock of the Company through accumulated payroll deductions. Offerings under this plan have a duration of 24 months (the "offering period"). On the first day of an offering period (the “enrollment date”) the participant is granted the option to purchase shares on each exercise date at the lower of 85% of the market value of a share of the Company's common stock on the enrollment date or the exercise date. The participant’s right to purchase common stock under the plan is restricted to no more than $25,000 per calendar year and the participant may not purchase more than 5,000 shares during any offering period. Participants may terminate their interest in a given offering or a given exercise period by withdrawing all of their accumulated payroll deductions at any time prior to the end of the offering period. The fair value of the estimated number of shares to be issued under each offering is determined using the Black-Scholes option-pricing model. The Company issued 51,438 shares and 73,702 shares from the ESPP during the nine month period ended November 30, 2019 and 2018, respectively. Share-based Compensation Expense Share-based compensation expense and related income tax benefits related to all the plans listed above were as follows (in thousands): Nine Months Ended November 30, 2019 2018 Compensation expense $ 4,904 $ 3,335 Income tax benefits $ 1,030 $ 700 Unrecognized compensation cost related to the Company's employee equity grants at November 30, 2019 totals $8.9 million and is expected to be recognized over a period of 2.50 years.

Acquisitions

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	Acquisitions In April 2019, the Company completed the acquisition of all the outstanding shares of K2 Partners, Inc. (“K2”) and Tennessee Galvanizing, Inc. ("Tennessee Galvanizing"), two privately held companies. K2 provides powder coating and electroplating solutions to customers in the Midwest and Southeast from locations in Texas and Florida. Tennessee Galvanizing provides galvanizing solutions to customers throughout the United States. These acquisitions expand the Company's geographical reach in metal coating solutions and broaden its offerings in strategic markets. The goodwill arising from these acquisitions was allocated to the Metal Coatings segment and is not deductible for income tax purposes. In August 2019, the Company completed the acquisition of the assets of NuZinc, LLC, a privately held plating company in the Dallas-Fort Worth area. The acquisition will increase the Company's footprint in electroplating solutions within its Metal Coatings segment. The goodwill arising from this acquisition was allocated to the Metal Coatings segment and is deductible for income tax purposes. In September 2019, the Company completed the acquisition of all the assets of Preferred Industries, Ltd. ("Preferred"), a privately held company based in the Dallas-Fort Worth area. Preferred provides powder and e-coating solutions to the automotive, HVAC, marine, transportation, medical, industrial, and plastics industries. The acquisition broadens the Company's offerings and expand its network of surface technology plants. This acquisition will be included in the Metal Coatings segment. The fair values of the net assets acquired, including property, plant and equipment, intangibles and goodwill may be subject to change as additional information is received and finalized. Accordingly, the provisional measurements of fair value for these items are subject to change. The Company expects to finalize the valuation as soon as practicable, but not later than one year from the acquisition dates. The Company paid approximately $ 60.6 million for these acquisitions, net of cash acquired, and expensed $0.4 million of acquisition related costs. The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed, in aggregate, related to these acquisitions as of the date of each respective acquisition (in thousands): Assets Accounts receivable $ 4,737 Inventories 1,728 Prepaid expenses and other 22 Property, plant and equipment 3,599 Intangibles 19,325 Goodwill 36,443 Liabilities Accounts payable and other accrued liabilities (1,574 ) Contingent consideration (1,791 ) Deferred income taxes (1,861 ) Total purchase price $ 60,628 The goodwill resulting from these acquisitions consists largely of the Company’s expected future product sales and synergies from combining the products and technology with the Company’s existing metal coatings portfolio. In addition to the initial cash payment upon closing for the K2 acquisition, contingent consideration of up to $2.0 million is payable based on the achievement of specified operating results over the three year period following completion of the acquisition.

New Accounting Pronouncements	Recently Issued Accounting Pronouncements In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instrument s (“ASU 2016-13”), which modifies the measurement of expected credit losses of certain financial instruments, including the Company's accounts receivable and contract assets. The Company will adopt ASU 2016-13 in the first quarter of its fiscal 2021 utilizing the modified retrospective transition method. Based on the composition of the Company’s accounts receivable and contract assets, current market conditions, and historical credit loss activity, the adoption of ASU 2016-13 is not expected to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract ("ASU 2018-15"), which aligns the accounting for implementation costs incurred in a hosting arrangement that is a service contract with the accounting for implementation costs incurred to develop or obtain internal-use software, in order to determine the applicable costs to capitalize and the applicable costs to expense as incurred. The Company will adopt ASU 2018-15 in the first quarter of its fiscal 2021. The standard can be applied either prospectively to implementation costs incurred after the date of adoption or retrospectively to all arrangements. The Company intends to adopt ASU 2018-15 using the prospective approach and the adoption is not expected to have a material impact on its consolidated financial statements.
