Commercial Loading & Overhead Dock Door Installation DFW

Another possibility is the scissor door design in which bars unfold in a crisscross fashion to form a barrier. This type of door has the advantage of allowing visibility inside, and it is often used in places visible from the street or sidewalk. If necessary, security personnel and patrolling police can see what is going on inside at a glance. The scissor bars unfold into a track running along the floor, but this folds out of the way during the day. A common design for a loading dock door might be a series of steel sections rolling onto an overhead rolling mechanism. A variation on this design is the sectional overhead door in which larger panels roll upward to be stowed flat overhead. Both of these styles provide a strong door when one is needed, but the door completely disappears from the loading area to allow unimpeded entry.
