Subsequent Events [Abstract]
Subsequent Event	Subsequent EventOn June 23, 2022, The Company and Fernweh Group LLC ("Fernweh"), jointly entered into a definitive agreement whereby AZZ will contribute its AZZ Infrastructure Solutions Segment (“AIS”) to AIS Investment Holdings LLC (the “AIS JV”), and sell a 60% interest in the AIS JV to Fernweh at an implied enterprise value of AIS of $300.0 million. The sale is expected to result in cash proceeds to AZZ of approximately $228.0 million, subject to certain customary purchase price adjustments. As part of recognizing the AIS as held for sale in accordance with GAAP, the Company is required to measure AIS at the lower of its carrying amount or fair value less cost to sell. The Company will complete this assessment during its second quarter of fiscal year 2023. The Company expects the assessment will result in a non-cash loss on disposal of approximately $35 to $65 million. The loss on disposal will be recorded as part of discontinued operations in the Company’s financial statements. Following the close of the transaction, the Company anticipates that the AIS JV will be deconsolidated and the Company's 40% joint venture investment will be accounted for under the equity method of accounting. The transaction, which is subject to certain closing conditions, is expected to close before the end of fiscal 2023.
