Heat-Strengthened Glass
A Balanced Choice for Clarity and Strength
Heat-Strengthened Glass is produced using a process similar to that used for tempered glass, but with a slower cooling process. This creates lower surface compressive stress than fully tempered glass. As a result, this product offers performance between ordinary annealed glass and fully tempered glass. It provides a good balance of strength, flatness, and optical clarity. Its excellent flatness helps provide clear and accurate images. This makes it suitable for applications where clear sightlines are important. Our company has more than 30 years of experience in glass processing. We have focused on glass technology since 1995. Our quality team regularly inspects raw materials and finished products to ensure that every batch meets our quality standards. When our Heat-Strengthened Glass breaks, cracks generally extend to the edges of the glass, while the broken pieces remain in the frame. They are less likely to fall out immediately. This feature is particularly important for applications such as building curtain walls and skylights. The glass also has good resistance to thermal stress, which helps reduce the risk of thermal breakage. It is about 2–3 times stronger than ordinary annealed glass. It also has a lower risk of spontaneous breakage than fully tempered glass, making it a reliable option for many building applications.
Global Projects and Custom Support
We have supplied glass for many projects in different markets around the world. Our Heat-Strengthened Glass has certifications and complies with relevant Chinese, American, and Australian standards. These certifications help our products meet demanding international requirements. For custom orders, we can work from your drawings, specifications, or models. Our production equipment has been continuously upgraded over the years and can accommodate a wide range of glass sizes. If you have special size requirements, our technical team will evaluate your specifications and confirm whether production is possible. We also have a dedicated after-sales service team to answer your questions and help resolve problems promptly. We follow up on each issue until it is properly addressed. This provides reliable support throughout your cooperation with us.
