Tempered Glass for Doors: field notes, specs, and what actually matters
If you’re speccing a storefront or upgrading a lobby, Doors Tempered Glass has quietly become the baseline material of choice. To be honest, I resisted the hype a few years back—until I walked a couple of remodels and saw how far impact strength and optical quality have come.
Industry trend snapshot
Three things are steering demand: code-driven safety, cleaner sightlines (frameless doors, anyone?), and faster lead times. Many customers say the breakage behavior—granular, pebble-like fragments—feels reassuring in high-traffic entries and retail.
What it is (and how it’s made)
Tempering takes ordinary flat glass close to its softening point (≈600–650℃), then blasts it with cool air (quenching). That locks in surface compressive stress and internal tensile stress, boosting bending and impact resistance roughly 3–5× over annealed. In fact, that stress profile is why it dices into small fragments on failure.
- Materials: low-iron, clear float, tinted, or coated glass per design.
- Process: cut → edgework → wash → heat (600–650℃) → quench → optional heat soak.
- Testing: EN 12150 fragmentation, ANSI Z97.1/16 CFR 1201 impact, GB 15763.2; real-world use may vary.
- Service life: ≈25–30 years with proper installation and edge protection.
Product specifications at a glance
| Thickness options | 6, 8, 10, 12, 15, 19 mm |
| Max size | ≈3300 × 9000 mm (check handling limits) |
| Surface stress | ≥90 MPa typical (per EN 12150 methods) |
| Flatness / roller wave | ≤0.3 mm (8 mm ref.), real projects vary |
| Edgework | Seamed, flat polished, arrised; CNC cutouts |
| Options | Heat-soaked, low-iron, ceramic frit, IGU, laminated |
Applications that make sense
Frameless swing doors, sliding systems, automatic entrances, mall storefronts, shower enclosures, and insulated glass door leaves. For coastal or high-security doors, pair Doors Tempered Glass with lamination.
Test data and certifications
- Fragmentation: >40 particles per 50×50 mm (EN 12150).
- Impact: Class A per ANSI Z97.1/16 CFR 1201 (typical doors).
- Heat soak (optional): EN 14179 to mitigate NiS risk.
- Plant QA: ISO 9001; China CCC; project docs on request.
Vendor comparison (quick and honest)
| Vendor | Lead Time | Certs | Heat Soak | Price Index |
|---|---|---|---|---|
| Wangmei Glass (Yushui, Shahe, Hebei) | ≈7–15 days | ISO 9001, CCC, EN, ANSI test reports | Available (EN 14179) | $ (competitive) |
| Domestic Mill A | 10–20 days | Partial | Limited | $–$$ |
| Import B (EU) | 20–35 days | EN/CE, broad scope | Standard | $$–$$$ |
Real projects (short and sweet)
Retail entry, Jakarta: 10 mm low-iron Doors Tempered Glass, heat-soaked; reduced callbacks to zero over 12 months. Facility manager said, “surprisingly clear even under LED strips.”
Hotel lobby, Dubai: 12 mm fritted panels for privacy bands; ANSI and EN reports cleared in one submittal round. I guess the rapid sample turn helped.
Why this supplier
Origin matters: Yushui Economic Development Zone, Shahe City, Hebei Province, China—arguably the densest glass ecosystem on earth. Short supply lines, fast parts, realistic pricing. For doors, Doors Tempered Glass with optional heat soak is my default spec unless a project mandates laminated-first.
