Tempered glass is made by heating flat glass to near its softening point and rapidly cooling it on the glass surface, causing compressive stress to be distributed on the glass surface and tensile stress to be in the central layer. Due to the strong compressive stress, the tensile stress generated by external pressure is offset by the strong compressive stress of the glass, increasing the safety of glass use. The feature adopts horizontal tempered steel, so there are no hanging holes. The strength of tempered glass is about 5 times that of ordinary glass. When glass is damaged by external forces, it becomes particles larger than beans, reducing the harm to the human body. Can withstand rapid temperature changes, such as 5mm tempered glass, which can withstand temperature differences of approximately 200 degrees Celsius. Tempered glass, due to the risk of instantaneous rupture, should undergo a heat soak test to ensure safer use. Usage: Automobiles, trains, ships. Architecture, furniture, automatic doors, escalators, fireplaces, etc.
