DLF glass sheet: 3210 × 2250 mm
A DLF sheet of glass is 3210 × 2250 mm, 7.22 m². It weighs 72.2 kg at 4 mm, 108.3 kg at 6 mm and 180.6 kg at 10 mm. Float glass weighs 2.5 kg per m² per millimetre of thickness (2500 kg/m³, EN 572-1), and toughened glass weighs the same. DLF, 3210 by 2250 mm, is cut from the jumbo of 6000 by 3210 mm that the float line produces, and it is what most merchants stock and deliver: the practical unit for a shop without a crane. Below it come the half sheet, 2550 by 1605, and the quarter, 1605 by 1275.
