Material Science & Technical Advantages
Exterior Landscape Slate Paving Stone leverages high-density, metamorphic origin slate produced via thermal and geological deformation. This results in tightly interlocked grains (density ~2.81 g/cm³), minimal water absorption (<0.6%), and exceptional freeze-thaw resistance. Advanced CNC cutting and ISO 9001:2015-certified finishing ensure tight dimensional tolerances and uniformity in grey slate paving stones and custom slate coping stones profiles.
-
Compressive Strength: 55-68 MPa, outperforming generic outdoor tiles by over 20% (see chart below).
Flexural Strength: >15 MPa, optimal for heavy-traffic zones. - Slip Resistance: R11-R12 per DIN 51130 and ANSI A326.3, safe even when wet. (Industry requirement R10+ for walkways)
- Weather Resistance: No significant spalling or warping after 200 freeze-thaw cycles (ISO 10545-12).
- Corrosion Resistance: Chemically inert—ideal for petrochemical, wastewater, and industrial flooring where acids or salts are present.
- Versatility: Conforms to custom tolerances & aesthetics—available in natural split, honed, bush-hammered, and flamed finishes.
- Lifespan: 50+ years with minimal color fading or surface erosion.
- Environmental Impact: Contains zero VOCs, 100% recyclable, and generates lower carbon emissions compared to concrete alternatives (Source: IGS Sustainability Report 2023).
