Clear Float Glass 2mm~ 19mm Size: 1220x914mm/1830x1220mm/1830x2440mm 3300x2134mm/3210x2250mm Float glass is made by high-quality sand, natural ores and chemical materials by mixing them and melting them at high temperature; the molten glass flow into tin bath where the float glass is spread, polished and formed on the molten tin . The float glass has smooth surface, excellent optical performance, stable chemical capability, and high mechanism intensity. It is also resistant to acid, alkali and corrosion.
