Roll-up doors offer reliable protection from unauthorized entry as well as adverse weather conditions.  Made from connected strips of material (often metal) that are easily rolled up into a compact coil, they are available to suit any size opening and budget; and are also available for special applications (fire rated, high speed, insulated, etc).  
Suitable for both interior and exterior entryways for a variety of different building types, roll-up doors are a versatile solution, and generally include the benefit of reduced maintenance (and reduced maintenance cost) when compared to other types of doors.  They are also highly durable and will last for many years when used as intended.
Additionally, the small footprint required for a roll-up door simplifies the tasks of mounting and installation.  Roll-up doors are normally mounted directly to the wall above their associated opening, and do not require connection to the ceiling or roof structure of the building; as is required, for example, with sectional-style garage doors.
Roll-up doors are offered in several different material selections and finishes to suit a wide range of applications. They can be manually operated by a pull-chain or powered by a motor for ease of use.  
Versatile, durable, and low maintenance; roll-up doors are an excellent choice when considering the available options for overhead doors in your facility or residence.  Although they are most commonly seen in industrial and commercial applications, they can be an ideal choice for some residential applications as well.
