1200×600 ceiling tiles are one of the most common used in ceiling grid installation. Funnily enough, although they are called 1200×600 ceiling tiles, they actually measure 1195×595 millimetres. The small difference is down to the ceiling grid module which has to be slightly larger than the ceiling tile and measures the full 1200x600mm.. You can find our full range of 1200mm x 600mm below.
