A bracing system for a door having a height, a width, a periphery and adjacent surrounding structure. The bracing system includes a first anchor positioned adjacent the periphery and fixed to the surrounding structure. The bracing system also includes an anchor surface positioned on the surrounding structure adjacent the periphery substantially opposite of the first anchor. The bracing system further includes a beam fixed to the first anchor and having a distal end configured to be engaged with the anchor surface. The bracing system still further includes an actuator drivingly engaged to the beam. The actuator and the beam are configured such that activation of the actuator causes movement of the distal end with respect to the anchor surface.
