Challenges of Oversized Large Doors

When considering a door larger than normal (that might be referred to as an enormous door) many challenges arise for the architects, designers, millworks, builders and installers. Some of the most common problems associated with big doors include:

Warped Door

If the door is taller than seven feet tall and wider than four feet then the door will warp. Warped doors are a common occurrence associated with large doors. This can be annoying for the end user due to the constant maintenance calls required for dealing with the warping door (though it is good for the door service business).

Big Doors Are Heavy

If a door is large you are going to have a lot of weight to deal with. This excess weight causes many issues associated with the building, transporting, installing and maintenance of the door from inception and throughout the service life of the door.

Big Doors are Expensive

Heavy building materials require more time, manpower, resources and equipment to make the door and the result is a big door that is overweight. Heavy doors are expensive to deal with; expensive to crate, ship/transport, offload, finish, store and install.

Overweight doors require more expensive hardware, and the added stress on the frame and the structure requires more regular maintenance over time.

Modular = Newest Development in Large Doors

Sing Core technology has advanced to a completely new level by introducing the modular large doors for combating even more challenges associated with large doors; by creating doors that are shipped as individual components and assembled on-site.

These extremely large doors would cost thousands of dollars to ship (if not impossible due to their large size) but if made in modular components, the large door can be shipped flat-packed and sent by traditional shipping methods reducing shipping costs tremendously. And, the resulting big door can still be guaranteed not to fail!

True Flat Technology Goes Modular

Long known for the largest non-warping doors, Sing Core takes modular huge doors to the next level while still making their 50 year non-warp guarantee. The components are shipped separately and assembled on-site for the biggest doors that can still be fully insulated, operable and manageable without the heavy maintenance required for other big doors. Many connection methods are available for these large door projects including making components using our T Slot Panels as individual components that can be perfectly aligned on site.

Free Large Door Consultation

Of course, building such a door up to 50 feet wide is an art in itself. Each door is designed for its intended purpose. Some of the questions our specialized doors creators ask might include: Will your large door be underwater, in outer space, exposed to extreme weather, need to be bullet-proof, waterproof or soundproof? Also, “What kind of door will you need?” A large sliding door, pivot door, French door or other type of door, etc…

Commercial trade professionals are encouraged to contact us for a Free Large Door Consultation, so that you, your clients and the world at large can know what it is like to own an non-warping large door of any size.
