I have a client wishing me to build 2 garage doors.
I need to make them lightweight, non-warping.
The sizes of each door is about 12 ft. height, and each about 5 ft. width..
(maybe more....not measured yet)
I would like to do a honeycomb pattern...I did see sing panels online.
I would like to make these at home also...in my shop.
Cedar 1x6 on the exterior in a sun burst pattern...
1/4 " marine ply interior.....foam 1 1/2" filler
Just trying to come up with a workeable idea.
I have built doors like these in the past, and realize the issues involved.
I would like to use a frame of Cedar or.......2x4 or 2x6....with a channel
to accept the 1x6.....
I also have used threaded rod, to hold panels together.....
Just throwing out a light of thoughts, and wondering if there is any
direction that one may know?
Thank You

After Hurricane Andrew tore up a major piece of South Florida,
overhead garage doors were developed that could withstand
a 2"x4"x96" being used as a projectile fired from a compressed
air cannon.
The result was the fiberglass skin over urethane foam core
panel.
I've done a lot of this type of fiberglass work, but would not
attempt to build them when commercial product is so relatively
available.
Once you have the base panel, you could add whatever you like
to decorate using 3M 5200 as an adhesive.
Good luck.

Doubt either of the above meets basic spec.

A quick search of "fiberglass garage doors" produced these people.

Might be worth talking to them.
BTW, stainless is exactly that, it stains LESS.
Anything other than 316L isn't going to cut it.
Bronze is a better choice for a marine application.

+10 (or X10) on that.

A torsion box? I like them for a lot of things but it's going to make
a pretty heavy door.

Well, "lightweight" is a relative term.

What "spec" is that?
--
Very helpful, and I had similar ideas although using engineered 2x material
sounds good.
I would aim for lighter also. Using cement board will increase weight
although it is very durable.
Also one can get 1.5 " foam insulation.
I may hold the doors together with threaded rod.
On my web page I made "Huge Doors" and I mean quite large......
They held up very well.
So, with the video, and more thoughts, I am still in the process of
developing a strategy that will work.
Thank You.

For doors this size, and I assume hinged at the outside, I would strongly
consider going with a steel u-channel on the outside, with z-channel or more
u-channel on the inside with foam tight in between the angles. Then skin
them with sheet metal, glued and pop riveted, then coat them with the wood
decoration on the outside. Weight will be the key, and you simply can not
build as lightly with wood as you can with steel, and still meet the
torsional rigidity that a door of those dimensions only supported at one
side will require with anything but a two sided structure.

Any reason you couldn't make them bifold? Then each panel is only half
the width so the rigidity issue is much easier to solve.
If you're talking threaded rod, anyways, I don't see why could build in
a diagonal tension cable that would be much lighter than rod and
certainly more than strong enough. 3/32" SS is almost 1000# breaking
strength even though its derated for aviation use by 5X, it would
certainly be more than adequate for the purpose here...
