Looking to use space above bathroom for storage, its 2.8 wide (beam length) and about 4m long
Currently has 3x2 "beams" at 18" centres holding up the bathroom ceiling - so its not really usable for storing stuff
Plan is to add 6x2 C16 joists with 47x147 hangers bolted to the walls - slight overkill maybe, but plan to store books and stuff, so don't want to under engineer. Plus that keeps the 9" of insulation under the boards
Not sure what bolts to use, was planning on M10 Thunderbolt, but do I need 2 per hanger or 4? Or something else?
