WAREHOUSE ROLLER DOOR REPAIRS. This Roller Door in the loading dock area has been hit by a Forklift going underneath, when the clearance height of the Door was inadequate. As you can see by the corrugations, the Curtain (door) has clearly been stretched out of shape. In most cases our Skilled Technicians can panel beat the damaged Door back into being operational again. Although some damage is permanent after being impacted, this is a more cost effective option, at least initially, rather than a total Door replacement. Warehouse Door Repairs.
