101: Wind Load


Q: Good afternoon! I am interested in 2 of Schweiss  doors for a project in Mexico, I need price and put in El Paso, Texas, weight and delivery time I need 1 door 15 'high x 70' wide, the door is open on a minimum of 30 seconds because it is for the airport fire department. I need 1 door 18 ' high x 75' wide. Very important for both doors need to be very resistant to strong air currents. Both doors (bifold/straps) also need to know if I can buy just the door frame and the price, weight and delivery time, look forward to your reply.


Q: Need a price for a 40 X 16 Schweiss liftstrap bi-fold door. Wind speed 10.44 PSF F.O.B. Options I want are: insulation package, weather kit, 3 windows and auto-latch straps.


Q: Looking for a Schweiss Bifold strap door that is rated 130 mph exp C wind 100 psf roof and ground snow door will have 0-4 inch thick insulated panels on it 3# psf


Q: Not sure where u r located but I live near Pocahontas, Iowa. Had tornado come through last April and no one has had time to replace my roll up door, Guess I will never buy another roll-up, anyway I was looking into your Schweiss bi fold strap doors, let me know price and if u can get here before summer is here. Can you wind rate your doors. 


Q: Need a quote on a Schweiss Bi-Fold with liftstraps and autolatches that is rated for 130 mph windload. I also need lift straps and auto-latches priced. Do I need to provide you with the Florida wind codes?   Good day, 




Q: I need a price for a bi-fold door 40'-0" X 10'-0" clear. The door is going in Texas with a wind speed of 120 mph. I also need the technical info that goes with the door. Please add lift straps to the bid as well. Thank you, Harold


Q: I'm planning to build a 35 x 45 garage. I need one door with 14'w and 14' clearance. The other 12'w and 8' clearance. Are the door measurements the size of the physical door or the opening. The building will be re-bar reinforced poured concrete. Insulated Concrete Forms (ICF) is being considered. Since it is new construction, I can pour the columns and header to support any load for Schweiss hydraulic doors but favor bi-fold depending. After watching half the bible belt being blown away by tornados I'm going poured concrete for the high wind load. Which of your overhead doors, one piece or two piece, can be made to the highest wind loading? Do you have (hint - giving away a million dollar idea here) a 12 inch wide x 14 feet high "hinged door" that rests against the outside of the building on both sides of the Schweiss bi-fold or hydraulic door, that can be flipped (swung, closed, etc.) 180 degrees to cover the side edge of the door. This should be a manual operation and be able to be locked in position. This would provide a wind/rain seal to both sides of the door and provide strength to the door edges for a higher wind loading. I'm sure you already have temporary pole braces from the header to the floor to brace the door every so many feet along it's width. A common thing on garage doors here in Florida. I'm still in the planing stage. I have not, yet, found a contractor who does ICF in south west Florida. How can we work together on this project? Calvin


Q: Could you please send me tech info on a 44'-6" wide X 18'-0" High bi-fold strap door, insulated, with a 15'-0" clearance. Windrated for Florida. Remote opener and autolatch system.  Thanks


Q: I'm requesting a price on a 40x12 Schweiss Doors bi fold with a walk door in it. There was already a bifold door on it (not a Schweiss door) but a tornado blew it over the roof and bent it in half. This time I'm looking at something a little more sturdy. What kind of wind speed can your door handle.
