I was looking at just using Corten steel sheets (the pre-rusted ones) for the exterior walls since I'm obsessed with forest fires (surviving, not causing) and then I found out they are also available as preformed panels.
This kind of look is all the rage in modernist buildings right now (and also to recreate the old "cabin in a mining town look") but my primary concern is a fire proof exterior.
This is one example of the panels.

Anyone every used this before, or something similar?

So it is basically tin siding right? If so I see nothing wrong with that at all. Less maintenance also and yes it will help in case of a fire.

Hi I haven't used that same product but their are many types of metal cladding. I used metal roofing on my cabin and the high gable ends are done with same metal. I never wanted to back up there to paint or stain so metal was the answer. The rest of my cabin is log siding. When I had the chief fire fighter out to inspect he told me the worst fire deficiency for my place and most every cabin is they don't have any skirting. He told me the ashes will drift under the cabin and find something to start.
So this fall I installed skirting and it made a huge difference in my cabin heating as well. I skirted one inch from ground level and back filled with crushed rock. In the winter I bank the snow up around skirting which helps as well
In saying this I did the normal things like cutting brush and cutting crowns off the spruce up to seven or eight feet from the ground . I thinned out my stand of trees in a three hundred foot radius of the cabin as well so it will only support a ground fire. I also have a holding tank outside for my grey water because it's mandatory but this can be pumped around cabin using sprinkler system to make a green belt which will stop ground fire
The one problem I have is they will close the highway that runs by my place if their is a forest fire in the area. His happened to me last year and they wouldn't let me pass. I told them I needed to go and protect my property but they wouldn't budge. Now I call the fire station every morning to get a update of lightning strikes and where existing fires are and what's happening. They promise to protect my place and I believe them

They used it on a nearby job once. Seems to be the real deal, an expensive alloy that will fall out of fashion and be replaced long before its service life is over. Did you want an unbiased opinion?

Actually, it's steel not tin. I was thinking of using it because the rust naturally forms a protective layer on the metals surface and prevents further deterioration. The steel can last anywhere up to 50 years.
Another option would be to use Galvalume for the siding.

On a wall why not recycle rusty roof metal?

If you like and want the look, sure, but why not a Hardiboard type of siding for fire prevention? Hardiboard comes in a variety of styles. I'm contemplating Hardiboard lap siding and Hardiboard "stucco" styles.

While metal siding/roofing doesn't burn it does conduct heat quickly and can cause the wood beneath to catch fire. Borate fire protective layers come in 3 foot rolls and lessen this possibility.
I've never seen this particular product, but it looks hard to install around windows, etc. It seems to have a curled water drip edge on 4 sides. So what if your panel is 2" too long? I'd research installation with this carefully. On a small cabin you have a lot of windows, doors, penetrations etc. whereas on a large commercial installation (which this is used for mostly, I guess) you have large expanses of wall with no penetrations, making installation easy.

This has become standard building code in Alberta, at least on exterior sheathing. There are other varieties of this product now, but this is the one I know and I believe they were the original inventors of the product:
http://www.pinkshield.ca/
Have a read through the website, but some useful bits of info are found here: http://www.pinkshield.ca/why-protect.html & http://www.pinkshield.ca/installation.html Both touch on "Flames Spread values", etc...
In addition, during our floods of 2013, many homes which were built with this product, sustained much less mold/rot/warping damage as opposed to those homes built without. The product didn't allow water to penetrate the wood nearly as much, and also had an unexpected benefit in that it didn't allow mold to grow as much.
Again, there are now other products that are similar, but this is the one I know of first hand. It's very evident when driving through a new community and seeing bright pink houses everywhere before they get their home-wrap installed and exterior finish of choice. I saw it featured/demonstrated on two separate episodes of "Holmes on Homes" and have had it mentally bookmarked ever since. The other nice thing is that it can be painted on after the fact if you don't buy the pre-coated wood products. Thus, easy to retrofit, or add as an afterthought. Potentially very useful to those of you whom are in the forest in fire-prone areas.
