185: STRUCTURAL ENGINEERS CHOOSE HYDRAULIC DOORS

Hello, We are currently planning on the door design for a new building that should be built this year in France. The building is industrial type and is planned for aviation activities. While there are several door designs that could be suitable, the bifold offers some advantages that we are interested in. We saw that you delivered doors in Europe in the past. Could you provide a rough quotation for two bifold doors of 75x18ft including shipping to "Vannes, France" (an other identical building will be built at the same place for an other company). Best regards, Bastien Le Roux

We had one of your doors installed on our building by your professional Schweiss Door installation team. There are a set of paper manuals that were with the door, but in the past year have some rain damage to them. Do you have electronic copies on your Schweiss Doors web site that I could down load or could you send them to me? Strap Auto Side Latch Install Instruction Manual 600 (903.3), Bifold Door Installation Manual 100 (325), Safety Decals Placement Guide Manual 50 (311), Bifold Electrical System 820 Manual BW-2-1-208/240, Column Followers Instruction Manual 440 (950), Splicing Doors Instruction Manual 450 (850), Top Override Safety Switch Instruction Manual 510 (885), Auto and Manual Wind Pins Instruction Manual 410 (925/930), and Bifold Safety Information and Operations Manual 10 (300). Thank you, our structural engineers stand by your patented Schweiss bifold doors. They are outstanding.

Our structural engineers would like to use the Schweiss hydraulic doors for a mixed use project in Seattle to open up the large glazed end walls of a long 3 story galleria for ventilation and for air supply during a smoke exhaust scenario in connection to the fire alarm system. We want to confirm your one-piece door product is appropriate for our application. The doors are fully glazed and sit in steel portal openings 17' wide by 18'-10" high surrounded by structural glazing.

I am a structural engineer, need quote for a 42 wide by 20 foot clear door opening for a large industrial strength hydraulic door. Can I get Schweiss AutoCAD door drawings to better understand and explain to my client.
