Microstructural Profile of G368 Wulian Red Granite
An authoritative engineering analysis of Shandong's premier magmatic stone reserve.
G368 Granite, commercially recognized worldwide as Wulian Red Granite (or Five-Lotus Red), is a coarse-to-medium grained intrusive igneous rock belonging to the Precambrian granite formations of the Shandong peninsula, China. Characterized by its vibrant pinkish-red to deep salmon hue interspersed with subtle quartz matrix flecks and dark biotite clusters, G368 offers an optimal synthesis of aesthetic warmth and structural fortitude.
From a petrological perspective, G368 consists primarily of potassium feldspar (45%-55%), quartz (25%-35%), plagioclase (10%-15%), and minor accessory minerals including biotite and hornblende (<5%). The crystalline interlocking structure formed via slow deep-crustal cooling gives Wulian Red an exceptional microstructural density. This eliminates internal cleavage planes, rendering the material immune to atmospheric weathering, acidic rain erosion, and extreme freeze-thaw cycles common in northern hemisphere architecture.
Material Performance Comparison Matrix
Architectural specifiers must balance compressive load capabilities, flexural tolerances, and environmental degradation risks. Below is the certified lab testing comparison according to ASTM C615 and EN 1469 standards:

|---|---|---|---|
| Density (g/cm³) | 2.68 | 2.61 | ≥ 2.56 |
| Compressive Strength (Dry, MPa) | 162.4 | 135.0 | ≥ 131.0 |
| Compressive Strength (Wet, MPa) | 148.2 | 118.0 | ≥ 131.0 |
| Flexural Strength (MPa) | 15.8 | 11.2 | ≥ 8.27 |
| Water Absorption Coefficient (%) | 0.24 | 0.45 | ≤ 0.40 |
| Abrasion Resistance (Ha) | 42.5 | 35.0 | ≥ 25.0 |
Macro-Industry Engineering Solutions
How wholesale G368 Wulian Red Granite powers large-scale municipal, transit, and commercial envelope developments worldwide.
High-Density Transit Hub Hubs
Railway concourses, metro station platforms, and international airport terminals demand stone cladding capable of enduring continuous dynamic point loads and heavy foot traffic. G368 flamed slabs provide R11 slip-resistance and non-skid surfaces without degradation under heavy equipment roll-over.
Rainscreen Architectural Facades
Modern high-rise developments utilize open-joint ventilated curtain wall systems. Wulian Red's high flexural strength (15.8 MPa) allows for thinner cut-to-size slabs (e.g., 25mm or 30mm), reducing structural dead weight while ensuring high resistance to extreme wind suction loads.
Civic Plazas & Municipal Landscaping
Urban streetscapes require materials that resist chemical de-icing salts, vehicle oil spills, and freeze-thaw spalling. G368 kerbstones, tactile paving, and bush-hammered plaza tiles maintain color integrity under high UV radiation and intense public usage.
Global Supply Chain & Manufacturing Ecosystem
Direct quarry control from Shandong to global deep-water ports ensures absolute cost efficiency and batch consistency.

Surface Finishes & Localized Applications
Selecting the ideal surface texturing technique for specific climate zones and municipal requirements.
Flamed (Thermal) Finish
Exposing wet stone to high-temperature oxygen-gas flames pops the quartz crystals, resulting in a rough, slip-resistant texture. Ideal for exterior walkways, public squares, steps, and pool decks in freezing climates.
Bush-Hammered (Litchi)
Impacted repeatedly by a multi-pointed carbide matrix head, creating a uniformly pitted, lightened surface. Excellent for heavy traffic civic centers, kerbstones, wall caps, and landscaping retaining walls.
Polished & Honed
Diamond abrasive grinding reveals Wulian Red's deep quartz crystalline array. Recommended for interior lobby floorings, feature wall accents, elevator surrounds, and decorative countertops.

Frequently Asked Questions
In-depth answers regarding G368 Wulian Red Granite procurement, physical specifications, lead times, and global shipping.
What makes G368 Wulian Red Granite distinct from other Chinese red granites like G635 or G562?
G368 (Wulian Red) possesses a significantly higher flexural strength (15.8 MPa) and lower water absorption rate (0.24%) compared to G635 or G562 (Maple Red). Its mineral structure contains a finer quartz matrix, resulting in superior freeze-thaw durability and reduced color fading under extreme UV exposure. This makes G368 the preferred choice for heavy-duty exterior civic paving and exterior rainscreen facades in North America and Northern Europe.
What standard sizes and thickness options are available for wholesale orders?
We supply G368 in gang-saw slabs (2400mm up x 1200mm up), cut-to-size tiles (300x300, 600x300, 600x600, 800x800, 1200x600mm), as well as paving blocks (100x100x50/80/100mm) and kerbstones. Standard thicknesses include 20mm, 30mm, 40mm, 50mm, 80mm, and 100mm. Custom dimensions up to 150mm thick for heavy load-bearing zones are cut precisely to CAD drawings.
How does Rizhao Haichen Stone guarantee color consistency across multi-container project orders?
Color variation management begins at our quarry face. We extract blocks from the same geological layer for single project orders. During factory processing, our inspectors group slabs into Color Grade A, B, and C tiers under calibrated daylight lamps. Before crate packing, we conduct a full factory floor dry-lay to ensure smooth gradient transitions and color harmony across all panels.
What surface treatment is best recommended for outdoor pedestrian plazas?
For outdoor public areas, we recommend a **Flamed (Thermal)** or **Bush-Hammered (Litchi)** finish. Both textures produce high surface friction (Slip Resistance Value PTV ≥ 55 under wet conditions according to EN 14231), preventing slips during wet or icy weather while accentuating Wulian Red's natural stone character.
What is the typical FOB lead time for a 10-container (approx. 4,000 m²) order?
Our standard production lead time for a 10-container order of standard 20mm or 30mm cut-to-size tiles is approximately 14 to 21 days from deposit confirmation and drawing approval. Port delivery to Rizhao Port or Qingdao Port takes 24 to 48 hours, ensuring rapid maritime dispatch to global destinations.
Can G368 Wulian Red Granite be used for mechanical anchoring curtain wall systems?
Yes. G368 exhibits excellent anchor bolt pull-out load capacity due to its high crystalline density. It is fully compatible with undercut anchor systems, pin-type back slots, and aluminum alloy clip fasteners. We provide pre-drilled and pre-grooved slab fabrication directly at our workshop according to your structural cladding layout.
