We want to attach a fairly heavy glass entrance roof to an already built lightweight concrete wall and received a suggestion to fabricate steel brackets according to the attached image. The material would be 50 x 50 x 3 mm square profiles or similar. The attachment would be done with two threaded rods in the vertical part. "Fästmassa" would be used in the wall, and a bolt would be used on the other side of the profile.
However, the company that was supposed to weld the bracket was very skeptical. Not about the steel construction but whether the attachment to the wall will hold. The glass that will rest on the brackets weighs approximately 200 kg, and that weight will be distributed over four brackets, meaning 50 kg per bracket.
Every suggestion you get regarding lightweight concrete is essentially: drill a hole through the wall and attach a plate on the inside. Unfortunately, this is not entirely straightforward for us since the wall is already built and the ceiling and everything inside is finished.
Therefore, I'm wondering if there are any other smart solutions?

Yes, even though it is glass, snow will probably be able to stick to the roof, so you are absolutely right.
Actually, I was looking for a seriously over-dimensioned attachment so that you don't even have to worry about snow and the like.
