Hello. I have a 140 mm x 65 mm concrete lintel over a 2.4m window. and would like to hang tiles on the wall but not sure if it will take the extra weight. There is only one bar through it but plenty of bearing ie over 150mm each side. There are concrete blocks above but not that many on one side as its tha gable of a bungalow.
Cheers.
