Tempered Glass FAQs: Professional & Technical Answers
Q1: What are the core materials used for high-quality tempered glass bulk products?
Soda-lime float glass, with SiO2 content ≥ 70%, and optional low-iron ultra-clear formulations for high transparency projects.
Q2: Which ISO/ANSI standards does tempered glass for sale commonly comply with?
Most products follow ISO 12543 (Safety Glass), EN12150 (Tempered properties), ANSI Z97.1, and (when required) FDA/CE for architecture and food industry.
Q3: What is the typical surface compression value, and why does it matter?
90–180 MPa (per EN12150); higher surface compression ensures safety, resistance to shatter upon localized impact.
Q4: How does the thickness choice affect performance?
Thicker panels (e.g., 15/19mm) provide greater impact strength & thermal resistance, but may raise installation loads. Selection depends on application: 8–12mm common for doors/partitions, 15–19mm for heavy industry/petrochemical.
Q5: Which edge and shape options are available?
Available with seamed/flat/polished/circular edges, CNC-cut shapes (incl. notches/holes), and customized silk-screen/printed designs.
Q6: What installation standards apply for certified projects?
Installer should follow ASTM E1300 (Structural Glass), EN 12600 (Pendulum impact), local building codes, and use manufacturer-issued technical datasheets for anchor/load calculations.
Q7: What is the guaranteed lifespan of quality tempered glass for sale products?
With proper installation and maintenance, expected service life is ≥ 35 years, with a 10–15 year manufacturer’s warranty as standard.
