| Presentation | |
| The accompanying condensed consolidated balance sheet as of February 28, 2014, 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, 2014 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 ended February 28, 2014 is referred to as fiscal 2014. | |
| In the opinion of management, the accompanying unaudited 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 August 31, 2014, the results of its operations for the three and six months periods ended August 31, 2014 and 2013, and cash flows for the six month periods ended August 31, 2014 and 2013. These interim results are not necessarily indicative of results for a full year. | |
| New Accounting Pronouncements | |
| In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, issued as a new Topic, Accounting Standards Codification (ASC) Topic 606. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The premise of the guidance is that a Company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU is effective for us beginning in fiscal 2018 and can be adopted by the Company either retrospectively or as a cumulative-effect adjustment as of the date of adoption. We are currently evaluating the effect that adopting this new accounting guidance will have on our consolidated results of operations, cash flows and financial position. | |
| In April 2014, the FASB issued Accounting Standards Update 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”). The update changes the criteria for reporting discontinued operations and enhancing convergence of the FASB’s and International Accounting Standard Board’s (IASB) reporting requirements for discontinued operations. ASU 2014-08 is effective for a) all disposals or classifications as held for sale of components of an entity that occur within annual periods beginning on or after December 15, 2014 and interim periods within those years and b) all businesses or nonprofit activities that, on acquisition, are classified as held for sale that occur within the annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted, but only for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. We do not expect the adoption of ASU 2014-08 to have a significant impact on our condensed consolidated financial statements. |

| Stock-based Compensation | |||||||||
| The Company has one share-based compensation plan, the 2014 Long Term Incentive Plan (the “Plan”). The purpose of the Plan is to promote the growth and prosperity of the Company by permitting the Company to grant to its employees, directors and advisors various types of restricted stock unit awards, stock appreciation rights and options to purchase common stock of the Company. The maximum number of shares that may be issued under the Plan is 1,500,000 shares. As of August 31, 2014 the Company has approximately 1,484,000 shares available for future issuance under the Plan. | |||||||||
| Restricted Stock Unit Awards | |||||||||
| Restricted stock unit awards are valued at the market price of our common stock on the grant date. These awards generally have a three year cliff vesting schedule but may vest early in accordance with the Plan’s accelerated vesting provisions. | |||||||||
| The activity of our non-vested restricted stock unit awards for the six month period ended August 31, 2014 is as follows: | |||||||||

| Non-Vested Balance as of August 31, 2014 | 87,651 | $ | 40.28 | ||||||
| Stock Appreciation Rights and Option Awards | |||||||||
| Stock appreciation rights and option awards 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. | |||||||||

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 our 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. For the six month period ended August 31, 2014, the Company issued 35,582 shares under the Employee Stock Purchase Plan. | |||||||||

| Unrecognized compensation cost related to stock appreciation rights, restricted stock units and the employee stock purchase plan at August 31, 2014 totals $4,625,220. | |||||||||
| The Company’s policy is to issue shares required under these plans from the Company’s authorized but unissued shares and treasury shares. The shares under the plan were registered on Form S-8, filed with the Securities and Exchange Commission on July 9, 2014. | |||||||||

| Acquisitions | |||||||||||||||||
| Zalk Steel & Supply Co. | |||||||||||||||||
| On June 30, 2014, we completed our acquisition of substantially all the assets of Zalk Steel & Supply Co. (“Zalk Steel”), a Minneapolis, Minnesota-based galvanizing company, for a purchase price of $10.5 million and the assumption of $0.3 million in liabilities. The Company recorded $2.9 million of goodwill, which has been allocated to the Galvanizing Services Segment, and $3.8 million of intangible assets associated with this acquisition. The intangible assets associated with the acquisition consist primarily of trade names, customer relationships and non-compete agreements. These intangible assets are being amortized on a straight-line basis over a period of 19 years for customer relationships, 19 years for trade names, and 5 years for non-compete agreements. The acquisition of Zalk Steel was made to expand our existing geographic footprint in North America. | |||||||||||||||||
| Unaudited pro forma results of operations assuming this acquisition had taken place at the beginning of each period are not provided because the historical operating results of Zalk Steel were not significant and pro forma results would not be significantly different from reported results for the periods presented. | |||||||||||||||||
| Aquilex Specialty Repair and Overhaul, LLC | |||||||||||||||||
| On March 29, 2013, we completed our acquisition of all of the equity securities of Aquilex Specialty Repair and Overhaul LLC, a Delaware limited liability company (“WSI”), pursuant to the terms of the Securities Purchase Agreement dated February 22, 2013 (the “Purchase Agreement”). WSI provides the energy industry with specialty repair and overhaul solutions designed to improve mechanical integrity and extend component life. WSI offers services to a diverse base of blue-chip customers in the nuclear, fossil power, refining, chemical processing, pulp and waste-to-energy industries, serving clients that place a high value on reliability, quality and safety. WSI's offering is differentiated through advanced proprietary tooling and process technologies delivered by a uniquely skilled specialized workforce. The acquisition is part of our strategy to expand our offerings in the Energy Segment to enhance our presence in the power generation market. | |||||||||||||||||
| The Purchase Agreement provided for AZZ's acquisition of all equity securities of WSI for cash consideration in the amount of $275.7 million, which is comprised of $271.8 million as cash paid at closing and $3.9 million subsequently paid in connection with a purchase price adjustment based on working capital pursuant to the Purchase Agreement. | |||||||||||||||||
| The following consolidated supplemental pro forma information assumes that the acquisition of WSI took place on March 1, 2013 for the income statements for the three and six month periods ended August 31, 2013. These amounts have been calculated after applying the Company’s accounting policies and adjusting the results of WSI to reflect the decrease in interest expense that would have occurred under the new credit agreement entered into in connection with the acquisition of WSI and to reflect the decrease in depreciation and amortization expense that would have occurred assuming the fair value adjustments to property, plant and equipment and intangible assets had been applied on March 1, 2013, together with consequential tax effects. In addition, supplemental pro forma earnings were adjusted to exclude approximately $3.2 million of acquisition related costs incurred the three and six month periods ended August 31, 2013. | |||||||||||||||||

| Using the acquisition method of accounting, the total purchase price was allocated to WSI's net identifiable assets based on their estimated fair values as of March 29, 2013, the date AZZ acquired control of WSI. The excess of the purchase price over the net identifiable assets was recorded as goodwill. The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition: | |||||||||||||||||

| All of the $87.1 million of intangible assets acquired are assigned to customer related intangibles and technology. The goodwill recorded in connection with the acquisition is primarily attributable to a larger geographic footprint and also synergies expected to arise. These intangible assets are being amortized over 14 years for customer related intangibles, 19 years for tradenames and 3-9 years for technology on a straight line basis. Goodwill of $109.6 million arising from the acquisition has been allocated to the Energy Segment and will not be deductible for income tax purposes. During the six month period ended August 31, 2013, we expensed $3.2 million in acquisition costs related to the acquisition of WSI. | |||||||||||||||||
