Retirement Benefits [Abstract]
Defined Benefit Pension Plan	In the Company's AZZ Precoat Metals segment, certain employees participate in a defined benefit pension plan sponsored and administered by the Company. The pension plan calls for benefits to be paid to eligible employees at retirement, based primarily upon years of service and compensation rates near retirement. The plan is closed to new participants, while those participants already in the plan continue to accrue benefits. In conjunction with the acquisition of Precoat Metals, the Company assumed an accumulated benefit obligation in excess of related plan assets associated with the defined benefit pension plan of $32.7 million, which is included in "Other long-term liabilities" in the consolidated balance sheets. See Note 2 for a discussion of the acquisition of Precoat Metals.
