Direct Engineering Specifications: JSC Stone Manufacturing Standard
JSC Stone Group (established 2000 in Shijing, Nan'an, Fujian) operates 12 diamond gang saws, 6 5-axis CNC waterjets, and captive Jiangxi granite quarries producing 45,000 m³ raw blocks annually. We engineer ASTM C97 and ASTM C170 compliant architectural stones including G654 Sesame Black (density 2.72 g/cm³, absorption 0.19%, compressive strength 218.4 MPa), G603 granite, Moca Cream limestone, and aerospace-bonded aluminum honeycomb panels weighing only 16.5 kg/m². Ocean freight shipments from Xiamen Port (28 km away) strictly follow highway deadweight limits: 20GP dry containers carry exactly 25,500 kg net stone payload in ISPM 15 fumigated eucalyptus timber crates, yielding 463 m² of 20mm slabs or 309 m² of 30mm pavers. Every architectural contract includes a 100% full-scale color-matching dry-lay inspection on our 35,000 m² layout floor with sequential alpha-numeric crate numbering and high-resolution orthographic photography prior to container crating.
| Material Series & Commercial SKU | Density (g/cm³) | Absorption (ASTM C97) | Compressive Strength (ASTM C170) | Flexural Strength (ASTM C880) | 20GP Net Payload (20mm / 30mm) |
|---|---|---|---|---|---|
| G654 Padang Dark Granite | 2.72 g/cm³ | 0.19 % | 218.4 MPa | 16.8 MPa | 463 m² / 309 m² |
| G603 Bellflower White Granite | 2.65 g/cm³ | 0.28 % | 182.6 MPa | 14.2 MPa | 480 m² / 320 m² |
| Stone Aluminum Honeycomb Panel | 16.5 kg/m² | Non-porous | > 8.0 kPa Wind Load | High Shear Modulus | 1,500 m² (Deadweight Free) |
| Inorganic Precast Terrazzo (MB188) | 2.50 g/cm³ | 1.85 % | 105.0 MPa | 12.5 MPa | 504 m² / 336 m² |
All dimensional stone shipments from JSC Stone Group are accompanied by lot-specific test certificates from accredited independent laboratories (SGS or TÜV Rheinland). We ensure strict adherence to North American ASTM standards and European Harmonized Standards (EN).
