Heavy duty bi fold door track

[bs0716]

Hi,
I've created a set of bi-fold doors with two quite heavy glazed doors into a wide opening. I bought a track from B&Q but it isn't man enough and the doors drag on the floor. any help as to where to get a better track etc... sliding doors are not an option btw.
many thanks

Hafele springs to mind. I've used their folding gear on furniture in the past and it's good. Certainly not cheap but good quality. They do folding gear for most sizes and applications. Something like this might do your job? You'll have to check the weight of the doors though.
