Toughened glass, also known as tempered glass, is a type of safety glass that the strength is higher and usually broken into small pieces when breaking. It is used widely for commercial constructions and residential buildings.
1. Strength: It has 3-5 times higher strength than float/annealed glass.
2. Safety: Tempered glass broken to small particle fragment after breaking.
3. Special functions: Printing paint before tempering will be Permanent.
4. With Lanjing advanced tempering furnace, we have the ability to make the jumbo size tempering.
The max length can be 13000mm, height 3000mm.
| Parameter | Tempered Glass | Annealed Glass |
| Cooling Process | Rapidly cooled (quenched) after the heating process. | Slowly cooled after the heating process. |
| Durability | More durable as it has a higher tensile strength and excellent weather resistance. | Relatively low due to low tensile strength. |
| Cost | More expensive as specialised equipment and modern technology are used in manufacturing. | Less expensive, therefore, it serves as an affordable solution for projects with limited budgets. |
| Breakage Pattern | Leaves small, blunt fragments which helps reduce the risk of injury during or after breakage. | When broken, it leaves sharp fragments that increase the risk of injury. |
| Strength | Four to five times stronger than annealed glass | Weaker |
| Noise Reduction | Has better noise resistance due to increased glass density. | Limited sound reduction due to lower density and sound transmission class (STC) ratings. |
| Energy Efficiency | Higher as it minimises heat transfer. | Lower as it has a higher thermal conductivity, resulting in more heat transfer. |
| Lifespan | Longer | Shorter |
| Fabrication | Cannot be cut after tempering and specialised cutting tools are required. | Can be cut using standard glass cutting tools. |
| Heat and Thermal Resistance | Higher as it does not crack or break even in sudden temperature changes. | Lower; thus, it may crack or shatter with sudden temperature changes. |
| Impact Resistance | High as it cannot break easily, reducing the chance of break-ins and intrusions. | Limited |
| Suitability | Safety-critical applications | Decorative elements and non-structural applications |
| Clear, Low Iorn, Tinted, Coated, Silk Screen, Digitally Printed | |
| Glass Thcikness | Tempered: 3-19mm, Heat Strenthened: 4-12mm |
| Glass Standard | EN12150, ANSI2208,ASTM C1048,GBT15763.4,GBT15763.2GBT17841, 5 years warranty |
| Glass Size | MIN 300*300MM, MAX 13000*3000MM |
| Monthly Output | 50,000SQM |
