I have built a construction that will be hung under the ceiling with lights etc. I have made it from MDF and it weighs about 20-25 kg. The size is 1 x 2 meters. It will be attached to the ceiling with 6 plugs. One plug in each corner and one plug in the middle on each long side. The idea is some kind of hook where the plug is attached with a chain that is about 20 cm long. The load per plug will then be approximately 3-4 kg per plug. It must not fall on my head because then it would probably be the end. As you can see in the pictures, the ceiling is made of soft concrete with reinforcement. I don't remember what this type of ceiling is called.
What type of plug should I use to make sure it holds securely?
I would have used something similar to this. Hanging something heavy in just a plug, even though there are good plugs for aerated concrete, I would not do. [link]
