Hi all
I'm completely uneducated in civil engineering of any sort so please forgive my ignorance.
I'm having a large garage built with doors measuring 2.7 meters wide and 2.7 meters high, with roller shutter doors fitted.
The lintels the builder has fitted are concrete pre stressed 75mm (3inch) thick and are supporting one course of concrete block above them. The roof will be made of that corrugated plastic so NO heavy tiles etc.
Are these lintels adequate as a number of people have expressed concern?
Many thanks in advance.
