The Reasons Cause Glass Shatter
Date Posted:1 October 2014
Toughened glass is a fragile item. Even it is about four times stronger than ordinary annealed glass, it's still glass subcategory, made from silica. not as strong as metal. I have some customer think toughened glass is very strong and never break. and install them roughly.
Actually, the mean advantage of toughened glass is when it's broken, it shatters into thousands of tiny pebbles—this practically eliminates the danger of human injury caused by sharp edges and flying shards.
There are many potential causes for toughened glass shattered, The most common is damage to the edges of glass. Chips to the edges that occur when the glass is being packaged, shipped, or installed onsite.While such damage may not be readily apparent, stress concentrations around these imperfections can occur as the glass expands and contracts in response to in-service temperature changes, wind load, building movement, and other environmental factors. Ultimately, when those stresses cause the glass to break, the action may appear to have been spontaneous when, in fact, the circumstances for failure had been put in place months or even years earlier.
