Semi-toughened glass is produced by a process similar to that of toughened glass, but the cooling rate is slow, so the surface stress of semi-toughened glass is slightly less than that of toughened glass. Semi-toughened glass is superior to ordinary annealed glass in mechanical strength, wind pressure resistance, impact resistance and thermal shock resistance, and is more suitable for glass curtain wall. Semi-toughened glass does not belong to safety glass.
Haocrystalline glass has great advantages and competitiveness in processing 12-25mm thick semi-toughened glass, whether in processing output or quality control.
