Roller garage door installation in sectional concrete garage?

[Oggi]

Hi guys,

Looking for ideas on how to mount a roller door to my new sectional concrete garage that arrives soon. I'm concerned that as the panels are concave on the inside I'm not going to have enough (flat) surface to mount the rails and roller mounting brackets...
Someone mentioned fitting 8x2 wood to the area where mounts are reqd but I'm not sure how you'd fix the wood effectively (the concrete panels are notorious for being tricky to drill) plus I'd rather not introduce any wood at all into the garage having just specified as a low maintenance UPVC version (kinda defeats the object....)
Garage is a Leofric Moreton and the door will probably be a Gliderol mini.

Any (sensible) suggestions welcome from people who may have faced a similar issue before.

Thanks in advance.

I must be the only person to have thought about this judging by the lack of replies, either that or the only person dim enough to consider it
