Facilities for processing steel. One facility includes a line for producing packages; a plurality of stackable cassettes for receiving packages; a splitter subfacility; automated transfer apparatus; and an automated overhead crane. The line may be a slitting line with the packages being coils of steel, or a cut-to-length line with the packages being stacks of steel sheets. A premises of the facility comprises a loading area in which packages from the line are loaded into cassettes, a storage area in which cassettes are stored, and a transition zone including at least one transfer position. The automated transfer apparatus moves packages and/or cassettes between the transfer position and the splitter subfacility. The automated overhead crane moves cassettes between the storage area, the loading area, and the transition zone.

An aerial advertising display apparatus includes a support base for placing on a support surface, a lift mechanism mounted on the support base and being actuatable to change the elevation of an upper end of the lift mechanism above the support surface, and an attachment mechanism supported by the upper end portion of the lift mechanism. The attachment mechanism includes a rearward component attached to the upper end portion of the lift mechanism and a forward component attached to an advertising display mounting frame. The rearward and forward components are linkable to couple and decouple with and from one another so as to correspondingly attach and detach the advertising display mounting frame to and from the upper end portion of the lift mechanism.
