What People Are Asking



Have a project looking for a door for an airport hangar. Need price and weight of door. The hangar has tilt-up concrete panels.


need quote on a bifold. 45'x18' Building has tilt up concrete panels for Schweiss Doors.


Good afternoon, I am looking for pricing with estimated freight for three bi-fold liftstrap doors (size below) with sheeting if that is an option. This will be a new build and the building is a tilt-up concrete panel wall building. Thank you


I am looking at using your patented Schweiss bifold heavy-duty strap doors in a cement storage warehouse. It looks like most of your pictures are overhead doors that open upward. I am looking at using these for a door. Along with this the straps will have to be located on the inside but there will be cement dust on the inside. Also the electrical motors  will need to lock the door shut and be able to hold a wall of cement (17 ft high at 80 PCF) without opening. The doorway opening is 20 ft wide by 15 ft high. Currently we are looking at putting two equal size doors (10 ft wide by 15 ft high). 


Need (2) - 9' wide x 8' tall bifold doors with door frame and flashing for an insulated concrete form wall. The tip up concrete panel bifold door should be  8" thick and the foam on both inside and outside are 2.75" thick for a total wall thickness of 13.5". Would prefer to also have some sort of Schweiss door backup system in case of a power outage. Have you done that before? Also need a personnel door in the face of one of the doors. Need to be able to insulate them well to match the insulation capacity of the ICF system. The inner and outer steel flashing has to wrap around and over the edge of the foam to protect it about 3" of overlap. 


Planning a 56'w x50' deep building will need tilt up concrete panel doors. 14' walls and a 4.5 to 12 pitch truss roof. I want a 42'x 14' Schweiss strap bifold /manual latch door on the building. Quote on the door delivered to Alaska and door design specs  on the door header. With my pitch there is room to mount door hinge location up on the face of the gable to allow for a clear door opening of 14' in the open position. Double door truss at the gable will meet the load, but I would like specific design info from you. I'll install bifold commercial door. 


I need a heated shop door and I'm interested in a 38 foot x 15 ft. thermal insulated bifold liftstrap door going on a tilt up concrete panel shop with 18 foot walls. Also price your automatic bifold door latching system. 


Need 60 x 18 bifold tilt up concrete panel door in a 50 x 90 x 18 concrete building. End wall is open now. Tilt up concrete panels were poured 6 weeks ago and are now ready for door installation.


I was looking for a bifold tilt up concrete panel door 24' wide 16' high open height with a walk door on the left end. Supply a 4"x 4" square tube industrial strength door frame for this unit.

I am a developer in Vancouver B.C. Canada. I am buiding an 84,000sf commercial hanger building with 7 strata units at the Langley Regional Airport.

All door openings are 19' high to underside of concrete header. 4 doors are 60'wide; 1@50'wide; 1@45'wide and 1@75'wide. Structure is engineered for hydraulic door reactions and loads. All doors are to be insulated and pre-painted. Please also provide delivery schedule. I also have some questions regarding the operation of your doors that I could not find answers to on your web site. Could you please have a sales person contact me by phone which I have listed above. Thanks Best Regards, Ed


We are designing an airplane hanger inside an existing tilt up building. The exterior walls are concrete, 8" thick. We are interested in having two 51'-0" x 14'-0" openings with bi fold doors. We are interested in stability, ease of opening, the potential for remote operation, appearance and durability. Our location is Hawthorne Airport in Hawthorne, CA. We are in the design phase now and would like to address concerns and opportunities early in the process and also obtain a preliminary cost quote. How do we arrange for shipping and installation? Please contact me at the email above or feel free to call our Seattle office. Thank you, J. Steven G.
