Zhejiang Jingtai Glass Technology: Deeply rooted in the forefront of tempered glass, empowering diverse application scenarios with technology and quality upgrades.

The new standard addresses long-standing industry problems such as spontaneous explosions of curtain walls in winter; it also introduces new requirements for acid mist resistance, requiring no corrosion after 240 hours of exposure in environments with a pH of 2 to 11, expanding the application range of tempered glass to harsh environments such as chemical plants and coastal buildings.

In terms of application expansion, the new national standard includes, for the first time, curved tempered glass with a curvature radius of not less than 400mm, better adapting to the growing design needs of curved curtain walls in modern buildings; it also relaxes the application restrictions on glass thicknesses of 8mm and above in super high-rise buildings, providing a wider range of choices for curtain wall glass selection in super high-rise buildings. Furthermore, the new standard explicitly requires edge grinding and chamfering (radius not less than 0.5mm), effectively reducing the risk of edge breakage, which is estimated to reduce the breakage rate by approximately 40%; wind pressure resistance has been upgraded from a qualitative description to a quantitative indicator, requiring 6mm thick glass to withstand wind pressure of not less than 1.5kPa and undergo 3000 cycle tests. These systemic upgrades mean that the technological threshold for tempered glass companies will be significantly raised. Only companies with advanced tempering equipment and mastery of precise process control will gain a first-mover advantage in the new standard arena.

High-end production lines empower superior product strength. Since its establishment in 2007, Zhejiang Jingtai Glass Technology Co., Ltd. has consistently focused on the research and development and manufacturing of special glass deep processing. The company covers an area of ​​60.16 acres and has over 20,000 square meters of modern standard factory buildings. It is equipped with advanced domestic horizontal roller tempering production lines, fully automated insulated glass production lines, and bulletproof glass production lines, among other core equipment. Its products cover tempered glass, Low-E insulated glass, laminated glass, fireproof glass, smart dimming glass, and bulletproof and shatterproof glass, making it a professional and diversified high-tech enterprise specializing in the deep processing of special glass.

In tempered glass processing, stress spots are one of the important implicit indicators of quality. Stress spots arise from uneven cooling in different parts of the glass during tempering, leading to variations in stress distribution. These variations can manifest as noticeable "rainbow patterns" under certain lighting angles, affecting the glass's aesthetics and visual transparency. Industry practice shows that new-generation tempering furnaces, through optimized temperature control systems and upgraded cooling fan structures, can significantly improve the flatness and optical uniformity of tempered glass, effectively mitigating the visual impact of stress spots. Zhejiang Jingtai Glass Technology continuously focuses on and invests in refining and optimizing its tempering process, striving to achieve higher levels in key dimensions such as lightweighting, high flatness, and stress uniformity, providing customers with tempered glass products that offer more stable quality and greater visual transparency.

From a production process layout perspective, tempered glass deep processing encompasses all stages, including cutting, edging, drilling, screen printing, tempering, and lamination or hollow assembly. The company possesses a complete deep processing production chain, with organic integration and closed-loop quality control between each process. The company has established a provincial-level engineering technology R&D center and has accumulated numerous national authorized patents, covering multiple technical dimensions such as glass preparation processes, production equipment improvements, and product testing methods. Our products have passed the China Building Materials Testing and Certification Center's "CCC" certification and the EU's CE certification, serving the diverse needs of domestic and international customers with superior product quality.

From construction to home appliances, the application scenarios of tempered glass continue to expand. The core advantages of tempered glass—high strength, impact resistance, and thermal shock resistance—have led to a continuous expansion of its application boundaries. Construction and infrastructure projects remain the most important application scenarios. Engineering needs focused on safety, energy conservation, and aesthetics are driving the continuous upgrading of glass from ordinary transparent sheets to ultra-clear glass, larger panels, higher flatness, more stable optical consistency, and composite structures such as laminated or hollow glass. At the same time, applications in home appliances and furniture panels, shower enclosures, commercial displays, and some industrial and transportation applications are also spurring the continuous expansion of deep processing capabilities such as "high surface quality, easy cleaning, scratch resistance, and customized openings and printing." Especially in the fields of fine decoration and high-end residential prefabrication, high-quality tempered glass, which combines safety protection and aesthetic performance, is increasingly becoming the common choice of designers and homeowners.

At the forefront of industry technology, China's glass industry is accelerating its development towards high-end, intelligent, and green directions. In April 2026, at the 35th China International Glass Industry Technology Exhibition, innovative achievements such as precision curved multi-curved tempered glass and a new generation of intelligent temperature control systems for tempering furnaces were showcased. The combination of bending steel forming technology and 3D modeling enabled the structural precision of complex curved glass to reach the millimeter level, meeting the growing demand for curved designs in modern architecture. Meanwhile, technological breakthroughs in the photovoltaic field were equally noteworthy—ultra-thin chemically tempered glass has been industrialized in photovoltaic modules, possessing excellent impact resistance, weather resistance, and light transmittance, while significantly reducing module weight, providing key material support for the large-scale promotion of lightweight photovoltaic modules. The industrialization and promotion of these cutting-edge technologies are injecting a continuous source of innovation into the tempered glass industry.

Regarding green manufacturing and sustainable development, with the continued implementation of the "Work Plan for Stabilizing Growth in the Building Materials Industry (2025-2026)" jointly issued by six departments, the operating revenue of green building materials is expected to exceed 300 billion yuan in 2026, and the scale of the green building materials and advanced inorganic non-metallic materials industries continues to grow. Tempered glass plays an indispensable role in the green building industry chain, serving not only as a fundamental component of curtain walls and windows but also as the supporting substrate for functional glass such as Low-E insulated glass and energy-saving components.
