Help choosing between our Bottom Rolling Door and the Higher Power hydraulic door.

Paul Blake

We give you the pro’s and con’s for these two big hangar door systems commonly used in commercial jet and military environments.

When we talk about hangar doors that are wider than 90 feet it’s a well known fact that the bottom rolling door is king. Take a look out of your oval window 60-seconds before the wheels touch the asphalt and most aircraft hangars you see will utilize “the slider”.

But the bottom rolling door is no longer your only choice of door for a big opening. You might also consider the Higher Power Door which is our number one selling vertical lift door system. This door can significantly reduce the cost of your building, has an option to revert to DC power, and it requires no pocket space.  The majority of door sales for this hydraulic door system are considerably smaller (in opening size) than your average bottom rolling door, but don’t let that put you off – this door has some great features!

What to look for from your hangar door:

  1. A door that limits the width of the building.
  2. A door that limits the height of the building.
  3. A door that limits the number of motor operators needed for door operation.
  4. A door that can be operated without power if necessary.

Differences

Bottom Rolling Door Advantages
Over Higher Power Door

MANUAL DOOR OPERATION.
Door leafs can be opened or closed manually.

TAIL DOOR, FUSEULAGE OPENING ETC
Our bi-parting configuration can include a tail door or a fuselage opening. Options like this offer a reduction in building costs and maximize the size of jets that can fit inside of the hangar.

DOOR OPERATION
You do not need to be concerned with obstructions outside because the door doesn’t swing out over the apron. There’s no risk to any lighting, water pipes or cranes because the door does not swing back inside the building.

RETAIN HEAT OR COOL AIR
Only open as much of the door as you need to. This will limit how much heat or cool air is lost from inside the hangar.

SAFETY
Safety edge will stop the door if it comes into contact with something.

LEAD TIME
Less than 90 days.

MILITARY GRADE
Explosion proof specification available.

Higher Power Door Advantages
Over Bottom Rolling Door

NO BOTTOM RAIL.
You don’t need to prepare the slab for a track.

NO POCKET SPACE REQUIRED
Needs no additional space outside the width of the opening.

THIS IS A SINGLE LEAF DOOR
Could argue this has a greater insulation value.

Similarities

Common Strengths

DOOR LOADS
Both doors are ground bearing so only apply wind load into the existing structure

LOW MAINTENANCE
Both doors are ultra simple with few components that need adjustment.

ADA COMPLIANT
ADA compliant openings can be included.

WALK DOOR | WINDOWS
Both doors offer walk door accessibility and window frames to let light into the hangar.

Common Weaknesses

GALVANIZING
The standard doors do not include galvanised structural members. If you need galvanising you may pay more and should discuss it with your estimator.
