Lead Lined HM Door Frames

El Dorado's lead lined door frames are manufactured from cold rolled 16 gauge steel. 14 gauge and 12 gauge lead lined door frames are available upon request. We offer either fully welded frames or knock-down frames although knock-down door frames are not recommended for use with pivot hinges. Lead lined door frames shall be suitably reinforced for closers, brackets and all other surface applied hardware. Drilling and tapping of surface hardware is typically done in the field by the installer. Our lead lined door frames are painted with a coat of rust inhibiting primer paint prior to delivery.
