Our Door Features & Advantages

1) No loads on the building when operating

2) No header loads

3) No horizontal loads. Door is partly inside and outside the building.

4) Only lose 8" of height below header or truss when open

5) Probably safest door in the industry with solenoid check valves in cylinder bases so our door will not come down due to hydraulic line, hose or fitting failure.

6) Our system only runs motor 1/2 the time because gravity for closing saves electricity.

7) Factory installed system, no problems with contractor, owner installations and door manufacturer.

8) All doors custom designed for your specific project.

Bi-Fold Doors

1. Bi-Fold Doors are the oldest style of door (other than sliders).

2. Overall costs could be more than our door.

• a. The building has to be heavily re-enforced to carry both header and horizontal load.
• b. The wedge design when opened reduces significantly the net height.
• c. When considering the added building costs to strengthen the structure to carry the door loads the bi-fold door is always more expensive in the end.
• d. Another hidden cost of the bi-fold is the reduced net height when opened.

So if you need 12' clearance the building has to be several feet taller that with our door because out door loses 8" when opened.

Standard Hydraulic Doors

1. This style of doors only advantage is it doesn't lose any headroom, because it can be hinged at or slightly above header. It also can be installed in Quonset style building if building is strong enough without losing much width.

2. Disadvantages

• a. Very heavy horizontal loads add significant cost to building.
• b. Header loads add building costs to project.
• c. There is no safety mechanism in system to stop the door from falling if hydraulic line or fitting fails. They usually only have flow restrictor in hydraulic line, but the door will come down!

Our door has two valves (one in each cylinder base) that are always closed unless we send signal from panel or remote to open. Door will not come down from hose or fitting failure.
