SGG 4MM CLEAR TEMPERED GLASS- CE EN12150 / BS 6206 /CCC Standard Quality

4mm Clear Tempered Glass is cut 4mm clear float glass into customized size, then pass them into tempered furnace, which the heating  to near glass softening point of 700 degrees, then rapidly cooled, which let the outer surface of the glass in a state of high compression, and the core or center of glass in compensating tension. This production process make 4mm clear tempered glass to be a safety glass that 4-5 times stronger than ordinary annealed glass, that is why 4mm  tempered glass also called 4mm safety toughened glass.
Please note that the glass can not cut any more after tempered, even grinding edges, or other processing. Thus all design details of toughened glass must be confirmed before mass production. Like edge polishing, drilling holes, cut outs, etc.

Tempered  process: 

1. physical tempered glass, also known as hardened tempered glass/strengthened tempered glass. The glass is internally tension, externally stressed and when locally damaged, stress is released and the glass is broken into numerous small pieces that do not have sharp edges and corners. 

2. chemical tempered glass by changing the glass surface of the chemical composition to improve the strength of the glass, the general application of exchange for tempered glass. 

Degree of tempered: 

1. Full tempered glass: tempered degree = 2 ~ 4N / cm, tempered glass surface stress α ≥ 95Mpa;
2. Half tempered glass: tempered degree = 2N / cm, semi-tempered glass surface stress 24Mpa ≤ α ≤ 69Mpa;


1, high impact strength, 5 times higher than ordinary glass

2.bending strength, 5 times higher than ordinary flat glass

3.thermal stability, can withstand temperature changes of 200℃ 

4.safety glass, In case of super impact damage, the debris was scattered small granular, no sharp edges and corners, it is also known as safety glass. 


Tempered glass is safety glass. Widely used in high-rise building doors and windows, glass curtain wall, interior partition glass, ceiling, elevator access, furniture, glass railing and so on. Usually tempered glass can be used in the following industries:

1.construction, building, decoration industry (such as: doors and windows, curtain walls, interior decoration, etc.)

2. furniture manufacturing industry (glass coffee table, furniture, etc.)

3.appliance manufacturing industry (TV, oven, air conditioning, refrigerators and other products) 

4. daily-use products industry (glass cutting board, etc.)

Differences between Annealed Glass and Tempered Glass

1. Clear tempered glass 4mm reduces the risk of injury due to its nature of breaking into small, circular pieces instead of sharp, jagged shards.

2. Clear tempered glass 4mm is ease of clean-up if they ever do break.

3. Clear tempered glass 4mm is 5 times strength than 4mm  clear float glass.
