Build a carport. Instead of wooden posts, is flat iron possible?

Hello!

I am new here and hope that someone might be able to help me.

We want to build a carport directly onto our house. Dimensions approximately 10 m long and 2.70 m wide. The width is limited because then the neighbor’s wall begins.

To avoid wasting space in width, I would like to attach flat iron to the wall and attach the carport roof to it. So no usual wooden posts. Is something like this generally possible?

The wall is about 1.80 m high. For the carport I need a height of about 2.80 m (for a caravan). So the flat iron would have to bridge about 1.00 m in height. On the other side (at the house), a beam could be mounted normally at the height on the house.

Maybe someone can give me a tip.

Hi,

I can't answer your primary question. Sorry.

But you should perhaps clarify one point beforehand: The wall is on the neighbor's property. Does your neighbor know what you intend to do and has he agreed to it?

The geometric disadvantage of a flat steel in St37 is correspondingly dimensioned and not a problem. Maybe you can weld another sheet vertically, which stiffens it enormously. If you could do that on the neighbor's side with their consent, you wouldn't even have wasted space.

Thank you for the quick responses. The wall and the neighbor are not a problem. At the moment, the wall does not exist yet. I have agreed with the neighbor that we can build the wall completely on his property. This way I can use my entire 2.70 m.

The fact that it works with a flat steel already reassures me.

I can probably find out from the locksmith what dimension is required to replace, for example, a 10 cm wooden beam, right?

Well, I call that a nice neighborhood! If you are not related, I would get that in writing.

As I already wrote: it's all a matter of design. Properly dimensioned and constructed, you could even build a beam out of papier-mâché. Do you know the moments and (weight) forces that the beam and its support have to withstand? Flat steel is structurally not particularly bending stiff, you should take that into account. Without knowing the load that the part has to carry, no one will be able to tell you what you need. How many beams do you want to use? What does the whole thing weigh? Are wind/snow loads known? How exactly should the beams be fastened?
