1200×600 ceiling tiles and ceiling panels are the most commonly used in ceiling grid installation. Funnily enough, although they are called 1200×600 ceiling tiles, the ceiling panels 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 ceiling tiles and ceiling panels by 1200mm x 600mm below.
