One option out there is the scissor door model, which employs strong bars that open into an X-shape to create a blockade. The bars run on a floor track and is easily moved out of the way so that work flow is not interrupted. This design affords the advantage of visibility inside, and is regularly utilized in locations where foot traffic is fairly common. This way, law enforcement or security officers can easily see inside if there is any suspicion of trouble at the site. Another choice, a sectional
overhead door, is rolled into the space atop the door frame and like the scissor design offers a formidable barricade but can also be opened and moved out of the way easily. Usually opening into warehouses featuring high ceilings, the sectional door is one that can typically be installed quickly and without the need for significant changes to the building or doorway. If overhead space is limited, the scissor style or a side panel door could be just the thing for your business. These designs can also be installed with minimum intrusion on work flow.
