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 |
JSC Stone Group (Xiamen Jin Sheng Da Industrial Co., Ltd.) was established in 2000 in Shijing Town, Nan'an City, Fujian Province—the heart of the world's natural stone processing hub. Over 26 years of disciplined industrial growth, JSC has transformed from a primary stone sawing workshop into an integrated multinational architectural stone fabricator, quarry owner, and high-performance composite panel innovator.
Our Industrial Manufacturing Complex
Our operations span 57,000 m² of modern industrial manufacturing space divided into two specialized facilities in Shijing (Xiabian and Houpu Port Hubs) alongside our captive granite quarry concession in Jiangxi Province. We manage 12 heavy-duty diamond gang saws, 4 continuous automatic leveling lines, 8 16-head resin polishing lines, and 6 specialized 5-axis CNC waterjet routers capable of sub-millimeter precision milling.
Global Track Record: 300+ Landmarks in 50 Countries
From Kengo Kuma's monolithic broken-face black granite facade for the Kadokawa Culture Museum in Tokyo to 12,000 m² of frost-resistant paving at Helsinki's Mall of Tripla, JSC Stone Group has partnered with the world's most exacting architects and commercial general contractors.
