China G3401 Shanxi Black Granite Manufacturer, Factory
Product Description
Products Information
- Supply Advantages: Mineral purity and stable reserves, specialising in premium-grade materials. Annual production capacity meets overseas high-end orders of 500,000 square metres. High ore yield with no fissures or impurities, ideal for intricate carving and large-format slab processing.
- Logistical Convenience: Proximity to Tianjin and Qingdao ports facilitates containerised sea freight and break-bulk shipping to major European, American, Middle Eastern, Japanese, and Korean ports. Customs clearance assistance provided in compliance with regulatory requirements.
- Export Mainstays: Core G3401 grade boasts purest hue and finest texture, prioritised for premium projects and bespoke memorials; Dingxiang County secondary quarry material offers superior value for money, suitable for premium municipal and landscape paving, both meeting international export stone quality standards.
- Base Colour: Pure jet black/Imperial Black, with rich, uniform colouration and virtually no colour variation. Exceptional batch consistency delivers a pure black texture far surpassing ordinary black granite.
- Grain: Free from noticeable impurities or chaotic patterns, featuring a fine, dense texture. Premium grades exhibit subtle silver-grey veining (a hallmark of Tai Bai Qing), enhancing premium aesthetics without appearing jarring or disordered. Absent sesame spots or yellowish patches, this distinguishes it from G654's sesame grain, forming the core identifier of pure black stone.
- Comparison with G654 (Sesame Black): G3401 exhibits pure black without speckles, whereas G654 features a deep grey-black base with white sesame-like specks. G3401 boasts superior hardness and finer texture, targeting the premium market; G654 focuses on cost-effective projects, suitable for large-scale installations.
- Gloss: Polished finish achieves ≥95° gloss, delivering a mirror-like high-gloss effect with deep, translucent black. Flamed/Lychee surfaces exhibit uniform matte jet black without discolouration, offering slip resistance, a dignified texture, stain resistance, and easy maintenance.
| Parameters | Typical Values | Engineering Value |
|---|---|---|
| Density | 2.72–2.78 g/cm³ | Exceptionally dense structure minimises deformation during transport, hoisting, and dry-hanging, making it ideal for large-format slabs. |
| Water Absorption Rate | ≤0.12% | Ultra-low water absorption coupled with superior freeze resistance, seawater corrosion resistance, and stain resistance renders it suitable for coastal regions, frigid northern climates, and premium interior applications. |
| Compressive Strength | 230–250 MPa | Compressive strength significantly surpasses standard black granite, enabling use in high-end bridges, heavy-duty premium plazas, and airport VIP zones. |
| Flexural Strength | 22–28 MPa | Exceptionally high safety factor for dry-hanging installations, resistant to fracture and detachment, suitable for high-rise premium building facades. |
| Mohs Hardness | 7–7.5 | High abrasion resistance and scratch resilience, ideal for luxury hotel lobbies, premium residential flooring, and high-end countertops with no visible wear over extended use. |
| Acid/Alkali/Weather Resistance | Excellent (ASTM C615, CE EN 1341, SNI) | Maintains colour integrity for 50 years outdoors without fading, weathering, or degradation, withstanding intense Middle Eastern UV exposure, Southeast Asian acid rain, and severe European/American cold climates. |
| Radioactivity | Class A Stone (Non-radioactive) | Certified completely safe for interior applications, children's areas, food zones, and luxury residences. |
