Premium 20mm Natural Stone Flooring
Unmatched Durability & Timeless Design
Crafted from solid marble, these tiles offer a robust 20mm (3/4") thickness, engineered for high-traffic residential and commercial areas. The substantial build provides exceptional structural integrity and longevity, making it a permanent investment in your property's value. Each piece showcases the deep, cosmic black background and dramatic crystalline veining unique to this natural stone.
Versatile Prefabricated Sizes & Shapes
Available in a comprehensive selection of standard dimensions to fit diverse project specifications.
Standard Tile Dimensions:
- 12-inch Series: 12"x12", 12"x24".
- 16-inch Series: 16"x16".
- 18-inch Series: 18"x18".
- 24-inch Series: 24"x24", 24"x36", 24"x48".
- Metric Options: Including 30x60 cm, 60x60 cm (600x600 mm), and 90x90 cm.
Available Shape Profiles:
Choose from classic squares and rectangles to decorative patterns like herringbone, hexagon, subway tile layouts, mosaic sheets, and feature medallions. The inherent strength of the material allows for flexible application on both floors and walls.
Complete Customization Capabilities
Tailor every aspect to meet precise design requirements.
Surface Finish Selection:
While polished to a high-gloss sheen by default for maximum light reflection, alternative finishes are available:
- Honed/Matte Finish: Delivers a smooth, contemporary surface with minimal reflectivity.
- Textured Finishes: Includes tumbled, brushed, or flamed surfaces that enhance slip resistance and add rustic character.
Specialized Edge Profiles:
Upgrade installations with custom-milled edges for seamless transitions:
- Beveled Edge: A clean, angled detail.
- Bullnose Edge: A fully rounded edge ideal for stair treads or curbless showers.
- Ogee Edge: An elegant S-curve profile for sophisticated trim work.
These profiles ensure perfect junctions with other flooring materials like wood or carpet.
Core Advantages
- Superior Load-Bearing Strength: The full-body thickness prevents cracking under heavy loads.
- Inherent Natural Beauty: No two tiles are identical; each features its own organic veining pattern.
- Adaptable Aesthetic: Compatible with modern minimalist designs as well as traditional opulent interiors.
- Low Maintenance Luxury: Properly sealed marble is stain-resistant and easy to clean with pH-neutral products.
Quality Assurance & Inspection Guidelines
We uphold rigorous standards from quarry selection through final fabrication. This guide outlines key inspection points to verify product integrity while acknowledging the natural characteristics of genuine marble.
Defining Acceptable Natural Variation
Marble is an organic material. The following are inherent traits that contribute to its authentic beauty:
Expected & Acceptable Characteristics:
- Color Tone Variance: Subtle shading differences between tiles or within a single slab are normal.
- Unique Veining Patterns: The white and gold calcite veins will vary in prominence and distribution.
- Micro-Fissures: Superficial hairline textures that do not affect structural stability.
- Minor Pitting & Crystalline Formations: Small surface voids or visible crystal clusters are natural occurrences.
Identifying Unacceptable Defects
The following issues relate to fabrication quality or handling damage:
Critical Non-Conformities:
- Structural cracks that compromise tile integrity.
- Significant chips or breakage on edges or corners.
- Dimensional inaccuracies exceeding tolerance (e.g., thickness outside of ±1mm for a nominal 20mm tile).
- Noticeable warping or bowing preventing flat installation.
- Inconsistent surface finishing (e.g., dull patches, deep scratches not consistent with the specified polish).
Recommended Inspection Protocol
For thorough verification during pre-shipment inspections:
-
Material Authentication:
- Visually confirm the stone matches the "Cosmic Black" marble specification—deep black base with distinct crystalline veining.
-
Dimensional Verification:
- Measure thickness at multiple points across a statistical sample of tiles.
- Check length/width against ordered sizes using calibrated tools.
- Use a straightedge to test for surface flatness along edges and diagonals.
-
Finish & Surface Examination:
- Inspect under bright light for uniform polish across the entire surface area.
- Identify any unacceptable polishing marks, epoxy fill repairs, or cloudy residues.
-
Structural Integrity Check:
- Gently tap tiles to detect hollow sounds indicating potential lamination issues (rare at this thickness).
- Conduct a visual scan for penetrating cracks on all surfaces.
-
Packaging & Documentation Audit:
- Verify secure packaging with adequate corner protection and interlayer separation within crates/pallets.
- Confirm all shipping labels accurately list product description (20mm Cosmic Black Marble), finish type, lot number, and quantity.
-
Sampling Methodology:
- We recommend employing an ANSI/ASQ Z1.4 AQL sampling plan using random selection from multiple pallets throughout the shipment load—not just top-layer crates—to ensure representative quality assessment.
