Material Properties & Technical Standards
Sintered stone is an engineered architectural surfacing material composed of 100% natural inorganic minerals, including feldspar, quartz, silica, and mineral oxides. The raw blend undergoes high-pressure compaction exceeding 36,000 metric tons, followed by thermal firing in automated kilns at temperatures above 1200°C. This sintering process eliminates internal voids and creates an ultra-dense, non-porous structure without polymer resins, differing fundamentally from resin-bound surfaces or sedimentary stones.
- High-Density Impermeability: The non-porous surface blocks liquid absorption (≤ 0.05\%), preventing oil, acid, and wine staining without requiring chemical sealers.
- Extreme Thermal & Fire Resistance: Graded Class A1 non-combustible; direct contact with hot cookware or direct flames produces no scorch marks, smoke, or toxic emissions.
- Mechanical Surface Hardness: Rated at Mohs hardness 6 to 7, providing high resistance to scratch damage from metal utensils and heavy foot traffic.
- Zero Resin & UV Immunity: The inorganic mineral formulation remains stable under ultraviolet radiation, preventing surface yellowing or thermal degradation in exterior wall installations.
| Technical Parameter | Standard Testing Method | Value / Performance Metric |
| Bulk Density | EN ISO 10545-3 | ≥2.40g/cm3 |
| Water Absorption Rate | EN ISO 10545-3 | ≤ 0.05%(Impervious) |
| Modulus of Rupture (Flexural Strength) | EN ISO 10545-4 | ≥50MPa |
| Mohs Hardness | EN 101 | Grade 6 – 7 |
| Thermal Shock & Fire Classification | EN 13501-1 | Class A1 (Non-combustible up to 1200°C) |
| Chemical & Stain Resistance | EN ISO 10545-13 / 14 | Class GA / Class 5 (Resistant to acids, alkalis, and solvents) |
| Thickness Specifications | Precision Caliper Gauge | 6 mm, 9 mm, 12 mm, 20 mm (±0.5mm tolerance) |
| Standard Slab Dimensions | Calibrated Edge Routing | 3200*1600mm, 2400*1200mm, 2700*1200mm |
We provide factory-applied surface textures for diverse design specifications:
- Polished Finish:
Diamond-buffed mirror finish with a gloss rating above 90°, accentuating deep mineral veining for interior walls.
- Honed / Matte Finish:
Smooth, non-reflective surface with a low-glare texture for high-traffic flooring and vanity tops.
- Silk / Soft-Touch Finish:
Satin surface delivering a tactile touch with anti-fingerprint properties.
- Bush-Hammered & Carved Textures:
Micro-structured relief mimicking split rock for exterior facades and non-slip paving.
Precision Cut-to-Size & Custom Fabrication
Fabricating sintered stone requires controlled cutting parameters and specialized diamond tooling to relieve internal material tension. Our production lines use 5-axis CNC bridge saws and multi-axis dynamic waterjets to execute custom cut-to-size orders without micro-fissuring or edge spalling.
Our workshops maintain strict tolerance control on custom fabricated units:
- Linear & Diagonal Tolerance: Maintained within ±0.5 mm per linear meter using optical alignment sensors.
- Miter Edge Profiling: 45-degree mitered apron cutting with high-strength structural epoxies for waterfall island countertops.
- CNC Cutout Execution: Calibrated CNC routers mill undermount sink openings, cooktop recesses, and faucet holes with radiused inside corners to distribute structural loads.
- Mechanical Facade Preparation: Pre-cut anchor kerf slots and back-drilled undercut anchors for ventilated curtain wall systems.
Key Commercial Application Scenarios:
- Kitchen Worktops & Waterfall Islands: 12 mm and 20 mm slabs engineered for residential kitchens and food service counters requiring certified food-contact safety.
- Exterior Ventilated Rainscreens: Lightweight 6 mm and 9 mm large-format panels mounted on aluminum subframes for building envelopes, providing higher UV stability than natural quartzite slabs or composite panels in architectural projects.
- Large-Format Floor & Wall Coverings: 1200*2400mm and 1600*3200mm wall panels that minimize grout joints in hospitality lobbies and elevator vestibules.
- Bathroom Vanities & Integrated Basins: Precision-glued sink basins fabricated from identical slab batches for color harmony.

Quality Control & Packaging Standards at Yigong Stone
Exporting large-format sintered stone slabs requires strict quality verification and heavy-duty structural packaging to prevent transit damage.
- Planarity & Camber Verification:
Each slab is tested using multi-point electronic leveling gauges to ensure surface camber stays strictly within ≤0.2%, preventing lippage during panel installation.
- Surface Defect Scanning:
High-lumen inspection lines check for micro-pinholes, glaze variations, and dimensional deviations prior to crate loading.
- Reinforced Steel A-Frame Racks:
Full-size slabs (3200*1600mm) are secured onto structural steel A-frames fitted with rubber isolation pads, perimeter timber clamps, and heavy-duty steel tie-rods.
- Heavy-Duty Fumigated Wooden Crates:
Custom cut-to-size countertops and tiles are packed inside ISPM-15 certified solid timber crates, lined with 15 mm EPE shock-absorbent foam and heat-sealed waterproof plastic wrap.
- Container Weight & Balance Optimization:
We configure container loads to comply with port road-weight limits (21 to 27 metric tons per 20GP/40HQ container), preventing cargo movement during ocean shipping.
Sintered Stone FAQ
Q: How does Yigong Stone prevent edge chipping and cracking during custom cut-to-size fabrication?
A: We utilize water-cooled diamond blades specifically engineered for sintered compacts, paired with programmed stress-relief lead-in passes on our 5-axis CNC saws and waterjets. This controlled tension-release process prevents corner micro-fractures during cutout milling and 45-degree miter edge profiling.
Q: What are the primary performance differences between sintered stone and engineered quartz surfaces?
A: Sintered stone contains zero polymer resins, providing complete fire resistance up to 1200°C and total UV stability for outdoor wall installations. Unlike quartz, sintered stone does not discolor under direct sunlight, resists thermal shock from hot pans, and provides higher chemical resistance.
Q: What is your MOQ and standard container loading capacity for sintered stone slabs?
A: Our standard MOQ is 100 square meters per pattern or one full container load. A 20GP container holds approximately 84 slabs of 12 mm (3200*1600mm, ~430 m²) or 160 slabs of 6 mm (~820 m²), packed securely on heavy-duty steel A-frames.
Q: Can you produce book-matched or continuous-vein sintered stone panels for large feature walls?
A: Yes. We manufacture mirror-image book-matched sets (Patterns A & B) and continuous multi-slab vein layouts. Each production batch is indexed to verify pattern continuity before high-definition scanning, ensuring precise grain alignment across adjacent panels for large interior installations.
