The Aircraft Hangar Building is only as good as it's "Door"
The door you choose is a huge decision, let Schweiss help you make this Choice. Explore the different
hangar door designs. Schweiss is willing to share with you the detailed door comparison of each
design so you can make the correct decision and select the door that works for you.
If you're thinking about buying a door for your aircraft hangar we are about to educate you on many
important features and decisions you have control of! There are no insider secrets with Schweiss
Hydraulic Doors we put all our cards on the table.
Did you know that a custom built door for your aircraft hangar does not cost as much as the hangar
itself? The word custom can be deceiving. The major hangar manufacturers quote the price of the door
included in the overall building quote. Have your building company separate the door package prices
from the building quote. Schweiss wants you to have an affordable new hangar building with a
beautiful automatic hydraulic or bifold door of your choice. You do not want to find out later that you
could of bought the exact same hangar from the same manufacturer less the door and saved
thousands. When someone is overcharging you Thousands $$$ for the door alone! Do your
home work on door shopping!
Like a customer once told us, "And to make matters worse, I found out
that...I was never given a door Choice!"
Some building designs may be under built and end up costing the end user of door and building more
money. Schweiss provides the building manufacture and door owner with a full set of detailed Spec
Sheets that provide the weights and moments that your door applies to the building. It's important to
build the building endwall / sidewall to accept the door of your choice. Before fabrication of the hangar
building, Schweiss can provide the building manufacturer with the Spec Sheets. Take no short cuts! Do it
Right the first time! Like a customer once told us, "And to make matters worse, I found out that... The
building endwall was not designed for the door"
Knowing about different door and building designs that can save you thousands of dollars. For
example, did you know that you can put a high quality hydraulic door in your aircraft hangar and save
thousands on your building cost alone!
Schweiss is also going to show you detailed pictures and technical drawings of doors so you will better
understand the hangar door yourself and save thousands when buying your prefabricated building.
Most airplane hangar building manufacturers will only tell you about the door, they happen to sell. And
guess what...You may end up buying a door that doesn't fit your needs!
Most people only know about one or two designs or they talk to a salesman who tries to sell them a
specific door regardless of whether it's the best suited for their specific situation. Each door is different
and each has it's place. Each door has a different price.
Don't get caught up in buying to low of a side wall building height, yes it's great to save money, but it's
also important to have some wiggle room when it comes to clear opening height. If you max the building
out and need more headroom at a later date--you'll find it hard trying to elevate the building because
your rafters are not high enough from the start. Think about headroom and plan for the future.
We're about to discuss the two different airplane hangar door designs. Schweiss manufactures the best two superior door designs available. Each have advantages and differences and some are better suited for specific climates and applications than others. Let us explain the many advantages and facts. This will give you a helpful overall guide to selecting the door of your choice to accommodate your building with the intention of getting the most for your dollar with the best door design money can buy.
The hydraulic door is one of the most recent door designs available. This "one piece" door

ram on each side of the door. The Schweiss hydraulic door is one of the best automatic door
designs available today. Schweiss has always offered people choice's and our superior hydraulic door

Door Completely open, door is cantilevered outward,laying flat Your building opening is 12' and your door opening will be 12' clear. Example : Lets say you building opening is 12' clear, and you need a door clear opening 12' To maintain a 12' clear opening, you need to attach the door 5" higher than the clear opening.
Hydraulic doors attach to your end wall / side wall of your building. The weight of the hydraulic door is cantilevered outward, requiring a strong door frame integrated into the aircraft hangar to support the weight and stress. Schweiss includes the specs with each door, provides the weights / forces and hinge locations.

Warning:
All doors equipped with remote operators should have a warning system
to alert persons in the immediate area that the door is moving.
Hydraulic doors that are "One Piece" and swing out when opening requires more open ramp space in front of the airplane hangar for the door to open. You can't park a vehicle or aircraft close to the door. Schweiss recommends you install a window within the hydraulic door so the door operator can view the doorway before operating the door.
P.S. If you park your plane or equipment to close to your hydraulic door opening
you may hear some expensive noises when opening the door
It's important to have a truss at the bottom of the hydraulic door to keep the door from sagging when it's opened...This same truss when located on the front side of the aircraft hangar door can collect debris and snow. Snow and debris must be kept clear from the front sides of the hangar for the doors to be able to open. Multiple truss options are available through Schweiss hydraulic doors to give you the clean look. Schweiss custom builds each door!
Door when opening, cantilevers outward, lying perfectly flat in the open position Do not keep the hydraulic door open during heavy winds, snowing or raining conditions.

Let us explain the many advantages and facts, let it be a helpful overall guide to selecting the door of your choice to accommodate your building with the intention of getting the most for your dollar with the best design money can buy.
The vertical bifold door hinges horizontally in the middle and is operated with an electric motor which
spools the straps to lift the door. Vertical bifold is the most popular design for hangar doors.
Surprisingly the vertical bifold door has been the people's door choice for many years and continues
to be....
Listed below are many advantages and facts that we'll share with you.
IT'S A FOLDING WALL - Clean, Neat Looking Door
Maintenance Free - Operation is relatively maintenance free
Less Moving Parts - with the new "Lift Straps" Gone are the pulleys and cables to service
Premounted electric motorized drive line attached to the bottom door panel
When in the open position bifold doors protrude out half the distance, exerting less forces to your
building structure and also less potential for wind or snow damage when open.
When a bifold door opens the door frame folds into a V ( sideways ) or a wedge acting as a huge truss
supporting each of the 2 piece bifold door sections. The larger the door wedge the less stress it exerts
onto the building structure.
Because these doors are so large, the fact that they fold in half instead of just swinging out together takes much of the stress off the front of the building.
Lift Straps are rated for 29,000 pounds and are used to raise the two section folding door frame. Bifold doors have multiple lift points through out the width of the door frame to evenly distribute the loads of the door across the building door header putting less stress on the hinges & door frame.
Double sets of heavy duty hinges support the folding door frames, 2 sets are better than 1.
Auto Locks Included - Powered by the drive motor to lock and secure the door
Automatic operation makes opening and closing easy and painless.
The fact that they fold in half instead of just swinging out, Bifold doors allows more open ramp/vehicle
space in front of the hangar for the door to open.
Allows the full use of the width of the hangar, make the entire end wall all door.
Bifold doors form a canopy when open, that provides shade and another important feature is it allows moisture to run off the open door canopy.
Zero Headroom Required - Lower your building cost, this alone will save you thousands.
Bifold doors folds in half and are slightly angled to allow rain or snow to drain off the front of the door
and not collect on top of it.
Bifold doors lift up when opening ( do not swing out ) -- Ice and snow is never a problem
Bifold doors do not require floor tracks that can fill up with debris or ice.
Best sealing door on the market - top / center / bottom gaskets
Requires electricity to operate lifting motor. If the aircraft hangar loses power, the door can be operated with a manual Hand Crank
Door Completely open, the door folds into a 24" wedge
Example: Lets say you building opening is 12' clear, and you need a door clear opening 12'
To maintain a 12' clear opening, you need to attach the door 24" higher than the clear opening.
Lose No Headroom, your building opening is 12' and your door opening will be 12' clear
The new " Lifting Straps " that raise and lower bifold doors has virtually made the bifold doors trouble free. Straps increase the speed of the door as it is opening. Straps will lift your door evenly at all times no adjustment needed. Your straps will never have uneven spooling, binding, jumping, moving and straps are self contained which are fully guarded for safety. Straps are safe rated for 29,000 pounds each ( cables 7000 are only pounds ea. ). Straps are a superior to cables. Your new lift strap bifold door will work for many trouble free years of use.
Schweiss includes the specs with each door, provides the weights, forces and hinge locations. Bifold door forces are less on the building structure because the door frame when open sticks out 1/2 the distance, and the bifold doors have multiple lift points ( 4 ) that evenly distribute the weight of the door across the building structure
Schweiss automatic locks are a one step process. You hold the button to open the door and the autolatches release automatically and the door opens. Autolatches let you operate the door from one side of the door opening, saving costly mistakes. Unlike manual latches where people forget to unlatch before hitting the open button.
Bifolding doors are made up of 2 equal door frames that hinges horizontally in the middle and at the top of the door. Bifold doors allows the door frame to be shorter in closer to your building in the open position. The farther the door frames are away from the building structure the greater stresses are to your building. With a Bifold door the stresses are minimal, because a bifold door hangs our half the distance also the double set of hinges share the weight of your door which all equates to longer door life.
