Diablo11215 Feb 2014 19:26Hello!
I’m new here and hope someone might be able to help me.
We want to build a carport directly attached to our house. The dimensions are about 10 m long and 2.70 m wide (approximately 33 ft long and 8 ft 10 in wide). The width is limited because the neighbor’s wall starts right there.
To avoid wasting any width, I would like to attach flat steel bars to the wall and mount the carport roof to them, instead of using the usual wooden posts. Is this generally feasible?
The wall is about 1.80 m (6 ft) high. For the carport, I need a height of about 2.80 m (9 ft 2 in) to accommodate a camper. That means the flat steel would have to span about 1.00 m (3 ft 3 in) vertically. On the other side (at the house), a beam could be mounted at the required height in the usual way.
Maybe someone can give me some advice.

When properly sized, the geometric disadvantage of a flat steel bar made of St37 is not an issue.
Perhaps you could weld another sheet vertically on it, which would significantly increase its stiffness.
If you could do this on the neighbor’s side with their approval, you wouldn’t even be wasting any space.

Diablo11216 Feb 2014 00:12Thanks for the quick responses. The wall and the neighbor are not an issue.
At the moment, the wall does not exist yet. I have agreed with the neighbor that we can build the wall entirely on his property. This way, I can use the full 2.70 m (9 feet) width.
Knowing that it works with flat steel is already reassuring.
I can probably find out from the metalworker what dimensions are required to replace, for example, a 10 cm (4 inch) wooden beam, right?

I can probably find out from the metalworker what size is needed to replace, for example, a 10cm (5 inch) wooden beam, right? As I already mentioned: it’s all a matter of structural design. Properly sized and designed, you could even make a beam out of papier-mâché. Do you know the moments and (weight) forces the beam and its supports need to withstand? Flat steel is not particularly stiff in bending due to its shape, so you should consider that. Without knowing the load the part must carry, no one can tell you what you need. How many beams do you want to use? What is the total weight? Are wind and snow loads known? How exactly should the beams be fastened?
