Talk About Free Standing Headers
 |
Schweiss Bi-Fold Doors manufactures the entire free standing header. You may retrofit it to your building endwall or sidewall. The free standing header is a quick and easy way to prepare your building for a bi-fold door. It consists of two side columns and the main header frame. |
|
The free standing header must be attached to the building and the building must be able to support the vertical and horizontal weights of the bi-fold door. You must tie the header and side columns to your building and provide a solid footing under the legs of the free standing header. |
| WHY USE A FREE STANDING HEADER? | |
 |
It's a nice easy way to prepare an existing building for a Bi-Fold Door. |
|
It provides a clean,flat,flush surface to attach your bi-fold door too. |
|
The free standing header will offer extra strength. |
|
It provides a nice straight and level place to attach your door to -especially on those older buildings. |
|
It's a quick fix -It's easier than remodeling the existing end wall for a bi-fold -and many times cost effective! |
|
It's a trade off -You would have to build a header up to your existing end wall and that's not free (Labor and material?) |
|
Free Standing Headers are made out of 4"x 4"x11ga tubes (2 across the full width, 2 legs and base plates). |
|
Larger free standing headers are made out of larger member sizes. |
|
The header comes all welded together -you must field weld or bolt both of the legs on. |
INSTALLATION OF THE FREE STANDING HEADER |
|
|
Installation is easy;attach the legs to your side columns and tie the header back into your existing building. |
|
Anchor the base plates to your concrete footing with anchor bolts. |
|
If there are no footings for smaller doors, just attach the side columns to your building posts or columns. |
|
We provide a step by step installation manual that is very easy to follow. |
|
If you want to build your own header we will provide you drawings on how to build it your self. |
|
Take pictures to send to the factory of your large opening, especially for larger header questions. |
IMPORTANT: |
|
|
The customer, contractor/owner and the building manufacturer are responsible to ensure that the building's structural design is capable of handling all the imposed loads that the bi-fold door exerts to your door header,endwall,and building. |
|
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. |
|
Schweiss Bi-Fold Doors will provide you with those loads that are applied to your building and door.We will provide you with our A-1, A-2, A-3, and A-4 Spec sheets for your actual measurements, movements, weights, and hinge locations.
