Toughened Glass in Kolkata
Toughened glass is heat-strengthened safety glass that's 4-5 times stronger than ordinary glass and shatters into small, blunt granules instead of sharp shards. In Kolkata, it's widely used for shop fronts on Park Street and Burrabazar, office partitions, glass doors, railings, table tops, shower screens, and balcony glazing. Common thicknesses are 8mm, 10mm and 12mm, with clear, frosted, or tinted finishes available.
Because toughening must be done before cutting or drilling, accurate measurements and edge/hole details matter at the order stage. When buying in Kolkata, check for proper edge polishing, BIS/IS 2553 compliance, and a clean toughening stamp.
