Which roof kit are you all using? We've been using K2 and like it but are struggling to get regular supplies - what do you prefer??

@dansk,
Are you on bulk discount with Hilti?
Despite the looks, design etc, it comes out between 30% and 50% more expensive than other systems we use, and it doesn't have any speed of install advanatges to make that difference up that we've been able to find.
Also their minimum order quantities on some items mean thay you need to committ to them for a significant number of jobs other wise you'll have a shed load of unwated bits.
Unless you've got some kind of special deal?
Schletter, SEN, Azur (oh and Click-Fit sometimes ) we also spec exactly what's needed for each job, and make sure that there's a couple of spares each time, - We'll soon have enough to do the mounting system of our 10kWp upgrade for free, (could probably do it now if we mixed it all up!)
We also buy all our stainless coach bolts, setscrews etc from fix8.co.uk - tell Laurence I sent you there.
We've also developed relationships with a local wholesaler who has extended his range just for us, - we use them for our commercial installs (just panels and mountings) so he was happy to add on extra mountings. For trapezoidal steel roofs the system we get from him (he's the only UK stockist) is so simple it cuts out install time down dramatically - it's not suitable for much else though.
If your having trouble getting K2, I'll speak to him tomorrow and see what his reaction is.
