Is tempered glass thicker, better quality?

Sources:Website | PublishDate:2021.07.12

Many people think that the thicker the tempered glass, the better. In fact, this is not the case. The thickness only affects the overall shape. The important thing is the tempering degree of the tempered glass. Many small manufacturers use semi-tempered glass or hot-bent glass in order to reduce costs. These glasses are susceptible to external factors. Thermal expansion and contraction are likely to burst. The broken glass ballast will have sharp edges and corners, which can easily hurt people. The safety performance of tempered glass produced by regular manufacturers is very high.

It is difficult to judge the quality of tempered glass from the perspective of glass material, because its appearance is the same as ordinary glass, and it is difficult to distinguish with the naked eye. Therefore, when buying tempered glass, you must choose a large scale, high reputation, and after-sales service. Only guaranteed brands and merchants can guarantee the purchase of assured products. Generally speaking, the quality of tempered glass that has passed national certification can be guaranteed. As long as you know the exact name of the tempered glass manufacturer or manufacturer, you can check whether the product has passed the certification from the official website of the National Certification and Accreditation Administration Commission.
