House entrance with curved roof

Earlier I inquired at a company that works with aluminum and from which I had the impression they could do something like this, but the quick response was: "here a welded construction is required, which is then anodized or powder-coated" One difficulty seems to be that even professionals do not necessarily immediately recognize what they have in front of them. The part is quite simple in its construction. The shape is created from two flat surfaces joined together at the center seam – practically automatically. In one direction, the material always remains straight. The surface is not bent in 3 dimensions. Brilliant, I say.

Certainly, there are companies that can bend sheets of this size (1.50 x 2.50 meters), but how do you find someone like that? I have already searched the internet for quite a while. 99% can bend narrow materials and profiles, but 1.50 meters wide... I have not found that one percent yet.

Hi

Here on the coast, I would look in shipbuilding, but that area will not be so easy to find in Hessen.

Shipbuilding? ... I probably won't find anything around the corner anyway. At the moment, it's primarily about the possibilities ...

Meanwhile, I am considering using several thin sheets instead of a 3 or 4 mm thick sheet, which you can’t bend yourself (because you can’t heat it), and riveting them together in the desired shape. I always like (well, mostly) making such things myself. Here, the experiment would be bigger than I normally "dare." If it goes wrong, a lot of material will be wasted. Here I have again 2 pictures of the paper model, without the house. This might make the shape easier/different to recognize.

I hope to be able to weld or solder the edges – of several thin, overlapping, and riveted sheets. I would also find the seam in the middle most elegant if welded, but in my mind, getting the sheets so tightly together at that spot that they can be welded well is difficult. The alternative would be an angle profile, which is flattened from 45° at one end to 0° at the other, then riveted from above on the right and left. The difficult part is “hitting” the right angle at the right place.

I would also weld the rivet spots from above if possible, so that water doesn’t get in.

Well... all this now only has a tangential connection to house building... but I enjoy it

Hello again

if it only needs to be rounded in one dimension, the matter is quite simple.
My approach would be: have two 3mm aluminum sheets rounded, you can surely find a metal construction company or a sheet metal worker for that. You could then cut the sheets to size and prepare them for welding, create the flange for attachment to the house, have it welded, finish the seam and cut edges, and then have it coated.

All that stuff with wooden construction, various substructures, multiple layers, and the like makes the thing look too heavy and bulky.
