We are doing kitchen remodel project. Our cooktop is on island in middle. Kitchen height goes from 10 feet to 14 feet high across width of 22 feet. We want to create hanging/suspending structure as shown in the picture on top of island. This will help us hide hood and will fill up the open space. My question is "what is the best way to fabricate this structure?". We have done necessary changes to roof structure to carry weight of about 3000 lbs. Hood weight is about 100 lbs. And other fixtures at best about 100 lbs. What material should be use to fabricate? should be use pipes or steel cable rope to suspend? Please help.
