Plant Restructuring and Asset Impairments [Abstract]
PLANT RESTRUCTURING AND ASSET IMPAIRMENTS	NOTE 3 — PLANT RESTRUCTURING AND ASSET IMPAIRMENTS As a result of the market downturn which began in fiscal 2008, we implemented a phased process to resize and realign our manufacturing operations. The purpose of these activities was to close some of our least efficient facilities and to retool certain of these facilities to allow us to better utilize our assets and expand into new markets or better provide products to our customers, such as insulated panel systems. As a result of actions taken in our restructuring, certain facilities in our engineered building systems and metal components segments are being actively marketed for sale and have been classified as held for sale in the Consolidated Balance Sheets. During the first quarter of fiscal 2010, we recorded an additional $1.0 million impairment for one of our facilities in the engineered building systems segment related to facilities classified as held for sale as a result of deteriorating market conditions. In determining the impairment, the fair value of assets was determined based on prices of similar assets in similar condition, adjusted for their remaining useful life. We plan to sell these facilities within the next 12 months. In addition, during the three and nine month periods ended August 1, 2010, we incurred $0.6 million and $1.9 million, respectively, in restructuring costs primarily related to idle facility costs. We did not incur significant similar costs related to our restructuring in the three or nine month periods ended July 31, 2011 and do not expect to incur significant similar costs resulting from this restructuring plan in the future. However, we did record a $0.6 million recovery in the three and nine month periods ended July 31, 2011 as a result of a legal settlement for a closed facility.

NOTE 3 — PLANT RESTRUCTURING AND ASSET IMPAIRMENTS

As a result of the market downturn which began in fiscal 2008, we implemented a phased process to resize and realign our manufacturing operations.
