Hi I plan to partition my garage which is now free my cars. I want to put up a timber framed wall as exists in most timber framed houses in Australia.(90 x
45 mm and clad with gyprock on both sides).However, along the ceiling where I want to place my partition is a huge steel 'I' beam along the exact line of the proposed partition. Do I attach the wooden frame to this beam say with self tapping screws or otherwise. Or do I leave it free at the top for fear of drilling into the beam will cause it to rust.
