Thanks for your reply.
From some alteration we made in another part of the flat , I know for sure that the contractor has used plasterboard with a metal stud structure
However I can only presume it is a metal stud that I have hit whilst drilling as I can not see behind the wall.
Hello,
I am installing some shelves (ikea Algot 650mm wide) in a 665wide cupboard.
My flat is in a new build where walls are made of plasterboard with metal studs.
I started installing Super Toggle fixings on one side without problem ... But unfortunately when drilling the wall to place...
