Several major factors must be considered when choosing an overhead door in an industrial setting. These include:
Overhead Door offers a full selection of doors to satisfy all the important requirements of industrial applications.
The first criteria of an industrial application are the size and design of the overhead doors. For new sites, the architect will set the specifics and either ask for custom made doors or will pick a readily available one that can be sized properly. Existing applications may need to replace an old or damaged door, or may need a new type of door to satisfy a repurposed application. Doors can be made in many sizes. Sectional doors available in heights and widths that depend on section size, whereas rolling doors are more amenable to non-standard sizes. There are practical limits on the weight of overhead doors such that an architect will specify multiple units to fill large spaces. Doors that are over 40 feet wide are available, but after that, doors may become too heavy, slow and unwieldy for many applications.
Door aesthetics may be very important in applications for showcase and commercial applications, but most industrial doors are not seen by the general public. Still, architects will want good-looking doors that complement the surrounding facility and that have the desired light infiltration characteristics. In some cases, the application will require maximum visibility and call for clear-panel doors made of tempered glass, Lexan or other transparent material. Other locations may want complete privacy/security and use doors with no lites at all. Door color may be a consideration, but fancy hardware is usually not used in industrial settings. However, if an industrial setting has public function, such as a winery with a public tasting room, fancier doors may be used in the areas visible to the public.
Many industrial overhead doors see little action. They are opened in the morning, stay open all day and then closed in the evening. In facilities that run 24-hours a day, these doors may seldom be closed. Secondary doors may be used infrequently and remain closed most of the time. In these situations, standard-cycle springs will suffice, and the door may be operated by chain hoist or manual lift. At the other extreme are doors that are constantly being opened and shut due to environmental or security concerns. These doors will require a high-cycle design and motorized openers. They also may need to open and close rapidly. The facility may have a central control unit at which all doors can be operated, or each door or grouping of doors may have separate controls. High usage industrial doors may require heavy gauge metal construction and premium moving parts that can withstand constant operation.
Many industrial applications face serious environmental challenges and require doors with special characteristics:
- Climate Control: Applications involving refrigeration require heavily insulated doors, as do sites in which the external prevailing temperatures differ substantially from the internal ones. The Overhead Door Model 850 uses advance Thermacore technology to provide an R-value of 26, perfect for food and beverage storage facilities, agricultural buildings, pharmaceutical plants and other heavy-duty applications. These doors are heavily insulated
- Weather and Wind: In many situations, applications may call for high wind pressure doors and/or doors that are tightly sealed against water and air infiltration. These types of doors require flexible weather seals and thermal breaks to support superior performance.
- Sound Attenuation: Doors may require heavy insulation to attenuate sounds entering or leaving the application, especially in mixed-use developments.
