  Tempered Glass 
   
 

Tempered glass is made by heating float glass to just below its softening temperature and suddenly chilling it with jets of cold air. It results the outer skins under powerful compressive stress and the interior with severe tensile stress. In consequence, the impact applied to the glass will be overcome by the compressional stress on the surfaces to assure safety of use.
 
 
FEATURES:
  • 5 times harder than ordinary float glass.
  • Once breakage occurs, the glass disintegrates into small cubical fragments, which are relatively harmless to human body.
  • It withstands abrupt temperature change of 220°C.
  • Sizes are produced per customer request, once tempered, cannot be cut down.
  • The appearance, thickness deviation and transmittance are almost identical with ordinary annealed glass.
  • The degree of curvature is 0.03%, which is only the 1/10 permitted value of international standard.
 
 

APPLICATION:

  • External use in general construction and buildings.
  • Glass doors and tables.
  • Various types of plates and cookware.
 
 
SPECIFICATION:
  • Thickness: 4mm-19mm
  • Sizes: From 300 x 300mm to 2440 x 6000mm. 
 
 

CAPACITY:

  • Can produce up to 25,000m2 tempered glass per month that will make us one of the biggest tempering production facilities in Malaysia.
