Tempered glass

Tempered glass is a kind of prestressed glass, in order to improve the strength of the glass, usually use chemical or physical methods, the formation of compressive stress on the surface of the glass, the glass to withstand external forces first offset the surface stress, thereby improving the bearing capacity, enhance the glass itself resistance to wind pressure, cold and heat, impact and so on. Tempered glass is used in building exterior walls, curtain walls, doors and Windows, partitions, stair handrails, etc., because of its high strength and impact resistance, it can provide better safety performance.
