How Is Tempered Glass Made? — Stepwise Manufacturing Process

1. Glass Cutting & Edge Processing Sheets cut, edges grinded/polished for stress relief
2. Pre-Inspection Surface flaws detected (ISO 12543, ANSI Z97.1 standards)
3. Heating Oven-heated to ~650°C until softening point; uniform temperature critical
4. Quenching Rapid air cooling produces compression on surface & tension inside: result is tempered structure
5. Quality Testing Bending/flexural, fragmentation, clarity & dimensional checks (ANSI/EN/ISO/CE/FDA where required)

Material, Technology, and Certification Standards

  • Raw Material: Top-grade soda-lime float or low-iron glass; SiO2 content ≥ 70% for strength and clarity;
  • Processing: Options including precision CNC cutting, edge polishing, drilling, screen printing, plasma/laser shaping;
  • Thermal Tempering: Fully automated lines ensure uniform quenching and stress profile;
  • Testing: Adherence to:
    • EN12150-2: Fragmentation & surface stress
    • ANSI Z97.1: US Safety Glass
    • ISO 9001, CE, CCC, SGS, TÜV certification

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.
