Lower Rolling Hangar Door

A well-designed hangar door system will remain functional in conditions that prevent other structures from moving. High winds, heavy snowfall, and power outages that interfere with other structures are easily overcome with a high-quality roll-up door.


A high-quality bottom roll-up hangar door is the strongest and most reliable door system available.

Design Options:

  • Flexible and easy to customize for virtually unlimited design options.
  • Unlimited size, maximum insulation, truck doors, pilot access doors, air chambers or filter banks, hatches, fairings, glazing, rear panels, unlimited options.
  • Manual doors are operated as opposed to electric motors to reduce complexity and cost.
  • Electric motor operators can be integrated into your system to meet your specific needs.

Other benefits:

  • Lowest life cycle cost of any design.
  • Flexible panel operation. The panels do not require any force to move them.
  • Long-lasting components that require very little maintenance.

Types of lower roller doors

All mobile panels

A configuration of roll-on-bottom hangar doors is known as All Moving due to the fact that the panels are not restricted in which direction they slide and are operated individually. This hangar door configuration is typically chosen for applications that require maximum flexibility in larger hangars, allowing for multiple aircraft without the use of stacking pockets. Simply move all the panels to the side of the shed that doesn’t need to be open. In northern countries, all mobile setups may require heated rails.

All hangar doors can be equipped with a variety of options to meet your needs. The doors can be operated manually or with an electric motor. Manual operation is popular in this configuration due to the fact that the operator does not have to push all the panels at once and can push one at a time with almost no effort. If the panel is chosen to be powered by an electric motor, the price tends to be a bit more expensive than the other configurations. Each panel is equipped with a motor and control panel and power is fed to each panel through the carriage duct power system along each rail. Other options are recommended with that option, such as safety edges along both edges and collision avoidance limit switches on each panel.

Individual stackable panels

Simply stackable bottom sliding hangar doors that can be installed in virtually any type of building to save money and space. The single stack door system has been specified for aircraft hangars, T hangars, industrial and agricultural buildings and even floating barges! When manually operated, these doors slide the same way as all moving doors, except they close in one direction and open in the opposite direction. They are “stacked” at one end, which is recommended to be a side wall or section built out of the building to store the doors while using the full width of the shed for the opening. In cases where space is not available on both sides of the opening, a wall is needed to stack the doors with the door open.

Two Partition Panels

The latest bottom roll up hangar door configuration is a very elegant design when space is not an issue. This door configuration hits in the middle and half of the panels open on one side while the other half open on the other side. This design requires an even number of panels and can be operated manually, but is usually powered by electricity, which means two motors are needed; one for half and one for the other half. This configuration has the same stacking requirements as a single stack configuration, but for both sides. Be prepared to give space to these doors. This setup really works great for reducing space inside and outside the building. An example is that instead of 6 panels on their own separate rails, they can now be placed on 3 separate rails, saving the space that the other two rails would take up. This is a game for some hangar owners.

multi-leaf doors

Named in part due to its principle of operation. In southern countries, the rails are protected from ice and snow in cold climates by a built-in pocket in the building that keeps the rails protected. The rails are also protected by the physical orientation of the panel stack, leaving no exposed rails in the closed position.

The layout of the rails only affects the location of the rails relative to the building; a north layout can be chosen for Biparting and Single Stack configurations.

South Lane Layout

Named in part due to its principle of operation. The rails remain outside the walls of the buildings because snow and ice are not as much of a concern in the south and the face of the panels on the outside of the building allows more space to be used for the customer.

Solar Powered Electrically Operated Gates

In some configurations, power roll-up hangar doors have unique power and control issues, which we have solved with our “solar option”. Solar panels are appropriately sized and installed on the exterior cladding or door cladding. Plate energy charges a battery installed in the door. The battery bank provides an uninterrupted power source for the motor that opens or closes the gate. The door works normally, even if power to the rest of the building is cut off! This solar option is available on all the different new door models.
