Tempered Glass: Float glass that is heated and then cooled rapidly to make it several times stronger than annealed glass. Tempered glass is safer than annealed glass because when it is broken it falls into pebble-like pieces without sharp edges.Features With high strength, good thermal stability and safety. No sharp edges on broken fragment.Performance Comparison Between Tempered Glass and Normal GlassTest Item6mmFloat Glass6mmTempered GlassBending-resistance strength50Mpa>150MpaImpact-resistance strength227g steel ball dropped from 750mm high, glass is broken1040g steel ball dropped from 1000mm high, glass is unbrokenThermal stability70 - 100broken25O - 327unbrokenBroken chipaSharp edges, can cause damagePebble-like pieces without sharp edge, safeSpecificationFlat tempered glass : Thickness4-19mm Max Glass Size:5200X2440mm Min Glass Size:250X150mmFlat tempered glass : Max Glass Size:5200X2440mmStandardGB/T9963-1998 Tempered Glass GB 17841-1999 Tempered Glass and Heat-strengthened Glass for Curtain WallApplicationTempered glass is mainly used for glass curtain walls, up-scale shopfronts, shower rooms, escalator rails, windows and doors on balcony, glass partition and areas where glass may have great potential in causing human damages such as public stadium where people are crowded.Products The treatment process of tempered glass is as: When heating glass close molten point, to carry out furnace and rapid cooling treatment on the surface of glass to produce compression stress while it is tension stress inside the glass, thus enhancing the strength and thermal stability. The glass will break into cellular pieces when the external force exceeds its strength. It is hence a highly safety glass. Max. Size (mm) :2400×6000 Min.
