DESIGN CRITERIA
Specifications and Important Design Criteria: What you need to make your door and building a perfect fit.
GENERAL / WIND LOAD DESIGN CRITERIA
The bi-fold hangar doors can be designed to the same loading requirements for live, dead and wind loads as the hangar building, to resist all anticipated loads without sagging, bowing or conflicting with its smooth and efficient operation. Your door design can be approved and sealed by a professional engineer registered in the state where the project is located with the proper wind loading and exposure.
IMPORTANT
The Customer, Contractor, Owner or Building Manufacturer
When your Bi-Fold Door is in the full open position, the Bi-Fold Door tends to pull away from the building at the hinge line, exerting considerable horizontal loads on the
building structure in the open position. Your building header design must meet standard deflection and strength criteria, both in vertical and horizontal directions to support
the Bi-Fold Door in all positions.
GENERAL / BUILDING DESIGN CRITERIA - Helpful Ideas
| • | The building header shall be designed to accommodate horizontal and vertical building deflections to support the bi-fold door in all positions (with the proper lateral bracing) |
| • | The buildings door columns must be framed of the proper design and size to reinforce the opening (with lateral bracing )and to carry all loads and vibrations imposed thereon. |
| • | Schweiss provides the A-1 , A-2 , A-3, and A-4 Spec’s Sheets : Read through & understand them and have your building designed for our door. The Bi-fold should have solid footing / sill directly underneath the door frame and extending beyond the door frame outward from the door to provide a base for the door’s base weather seal also prevent.flow of water (into or Under) the door installation. |
| • | The finished floor / asphalt of the building should be designed to prevent flow of water (into or Under) the door installation, Sills shall have a slight slope outward of the bi-fold door to prevent.flow of water under the door installation. |
WIND LOAD / GENERAL DESIGN CRITERIA
| • | Wind loaded doors: To meet standard local codes |
| • | Extra heavy wind loading requirements available. |
| • | Wind Pins: Furnished on door frames to increase the wind load strength & provide a sturdy installation. |
| • | Wall Pins: Are incorporated into the door frame to provide additional wind load when needed. |
ELECTRICAL DESIGN CRITERIA / GENERAL / FOR EACH DOOR INSTALLATION
Customer / Electrician Must Provide:
| • | Proper voltage & electrical service to the door's power unit. |
| • | Proper wire from the service panel to the up/down/stop switch on our door. |
| • | Install any electrical conduit. |
| • | Electrical components place on the door must meet the requirements |
