Engineering-Grade Natural Granite Products
Direct architectural supply lines for commercial plazas, high-traffic infrastructure, and exterior facades.
The Science of Flamed and Brushed Surface Engineering
Combining high-temperature thermal exfoliation with rotary abrasive brush refinement produces granite architectural surfaces that maximize friction without sacrificing tactile comfort or cleanability.
Thermal Micro-Spalling
Thermal exfoliation applies a continuous high-temperature flame (exceeding 1200°C) across the stone face. Unequal thermal expansion coefficients among quartz, feldspar, and mica cause surface crystals to burst, leaving a slip-resistant micro-relief that prevents pedestrian hydroplaning.
Diamond-Polymer Brushing
Standard flamed surfaces can trap dirt and create excessive abrasive drag. Our automated brushing lines utilize rotating abrasive heads embedded with silicon carbide and diamond grain polymers to soften sharp micro-peaks into an antique leather texture.
Chromatographic Recovery
Pure flamed finishes often result in a washed-out, greyish haze due to light scattering on rough surfaces. Secondary brushing burnishes micro-cavities, allowing native quartz and feldspar grain contrast to re-emerge while retaining high wet slip resistance.
China Factory 4.0: Supply Chain Resilience & Modern Capacity
Vertical control from quarry face extraction to dual-port maritime dispatch reduces intermediate volatility for civil engineering contracts.
Integrated Quarry Reserves
Rizhao Haichen Stone manages extensive quarry reserves in Shandong Province. Directly sourcing blocks guarantees shade stability across phased multi-year deliveries, shielding buyers from regional shortages and third-party block markups.
Automated Slab Production
Multiwire diamond saws combined with CNC bridge cutters maintain a thickness tolerance of ±1mm. Automated flame-brush continuous lines boost throughput efficiency by 50%, sustaining strict deadlines for port, airport, and railway contracts.
Dual-Port Coastal Synergy
Situated in the Rizhao Stone Industrial Park, our facilities access both Rizhao Port and Qingdao Port directly. Coordinated shipping logistics and container stuffing minimize transit wear, decreasing land freight expenditure by 30% compared to inland producers.
Global Enterprise Procurement Demands & Solutions
Engineered stone solutions configured for large-scale urban infrastructure, commercial developments, and transport networks.
Transit Hubs & Public Squares
Pedestrian concourses demand slip resistance exceeding PTV 36 under both dry and wet conditions, along with wear classes capable of enduring decades of rolling load friction without surface degradation.
Ventilated Rainscreen Facades
Exterior vertical cladding demands flexural integrity (Rtf ≥ 10 MPa) and low water absorption (≤ 0.4%) to resist wind load shear, cyclic freeze-thaw cracking, and moisture absorption in cold climates.
Integrated Structural Envelopes
Large infrastructure tenders increasingly consolidate raw facade stone with custom metal framework, curtain wall fittings, and window systems. Haichen provides unified material sets that accelerate project procurement.

Localized Support, Compliance & Future Roadmap
Minimizing technical risks with traceable quality controls and forward-looking digital manufacturing practices.
Comprehensive Verification
All shipments include complete EN 1341 (slabs), EN 1343 (kerbstones), and ASTM C615 test documentation. Pre-shipment batch checks measure dimensional tolerance, diagonal precision, and flexural limits under calibrated laboratory loads.
Dry-Lay Visual Layouts
For custom commercial elevations and large squares, our technicians run dry-lay floor pre-arrangements in the workshop. Pieces are calibrated for chromatic transitions and coded with directional identifiers before crate packing.
Digital Traceability & BIM
Our production incorporates CNC toolpath coordination and BIM file integration. Slabs, curbs, and curved segments can be mapped directly to digital design models, cutting field re-cutting waste and installation bottlenecks.
