I have never done a suspended ceiling myself. I am not a trader. It was easy enough.
Very fragile tiles break if you even look at them!!
I purchased these tiles to replace a number in a suspended ceiling that had been water damaged. The tiles were easy to fit and matched the existing tiles well.
A couple had damaged corners, presumably through transit. I used these for those that needed cutting up. They cut easily with a pad saw.
Saved a lot of money using the 1200s instead of 600mm pad. Good quality and about 30% cheaper than all the other quotes I recieved.
