Abstract
A roll-up overhead door assembly which is selectively moved up and down to open and close an opening and which is guided along sides of the opening by columns, the door having an open position, a closed position and a cleaning position. The door includes a drum positioned proximate the top of the opening, a flexible door panel connected to the drum and a drip guard. The door panel is attached to the drum such that when the door assembly is in an open position the door panel is wound around the drum. The drip guard partially surrounds the drum and is positioned and sized to catch residue falling from the drum or door panel overhead. The door panel is sized such that in the closed position the door panel is connected to a point on the drum so that the panel does not significantly overlap the drum. The door further includes columns on opposed sides of the opening and surrounding the guides. Each column comprises a backplate and, respectively, a cover plate removably attached to each backplate wherein one of either the backplate or the cover plate has side wall. The door assembly further includes a drainage trough for collecting moisture falling from the door. The drainage trough has a first end and a second end and is attached to a bottom edge of the door panel, and is configured such that drainage flows toward at least one end of the trough.
