If you’re chasing that crisp, contemporary façade with a natural edge, irregular blue quartz (and its cool-toned cousins) has quietly become the architect’s cheat code. Funny thing: most buyers land on a “white quartzite” page first, then ask for a blue tone. That’s fine—quartzite quarries typically yield a spectrum. DFL Stones, based at 1111-1112, Sinotrans Building, No.368 North Youyi Street, Shijiazhuang 050071, China, openly supports the blue selection as a customization path. To be honest, color stability and split-texture are the real reasons specifiers keep coming back.
- Thin, split-face panels (around 10–20 mm) for fast installs and lower dead load.
- Cooler hues—blue-gray, ocean-slate—paired with black window frames. Works outdoors and, surprisingly, in reception feature walls.
- Verified test data. Many customers say they’ve been burned by pretty samples with no ASTM proof. Can’t blame them.
| Model | DFL1308HWPB |
| Material | Quartzite (White standard; Blue tone selectable by lot) |
| Surface | Split-face, natural cleft |
| Size (panels) | 60×15 cm; 15.2×61 cm; 18×35 cm; irregular modules; custom on request |
| Thickness | ≈ 10–20 mm (real-world use may vary) |
| Applications | Exterior cladding, interior feature walls, selective floors |
- Materials: dense quartzite blocks selected for blue-white tonality and lower porosity.
- Methods: block trimming → slab slicing → split-face dressing → calibration → optional mesh backing → sealing (if specified) → final sort by hue.
- Testing & standards: ASTM C97 water absorption (target ≈ 0.2–0.6%), ASTM C170 compressive strength (≈ 150–200 MPa), ASTM C99 flexural strength; EN 1469 for cladding, freeze–thaw per EN 12371 for cold regions.
- Service life: 25–50 years with proper fixing and joint design; marine sites may need more frequent sealing. I guess that’s just good practice.
- Colorfast: mineral color, not a dye. UV-stable.
- Tough: high compressive and abrasion resistance; good for busy lobbies.
- Safer underfoot: the split texture gives natural slip resistance.
