Free Standing Headers

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.
