Quartz Exterior Wall Panel

Tested and certified by accredited international laboratories (e.g., SGS, Intertek), our quartz panels comply with major global architectural codes. 

Zero Water Permeability: Surface absorption rate under 0.05% prevents moisture penetration, eliminating freeze-thaw cracking, spalling, and sub-surface frost heave.

Controlled Thermal Expansion: Maintains dimensional stability across operational temperature ranges from -40°C to +80°C, reducing joint stress in rainscreen installations.

Inorganic UV Pigments: Formulated with mineral-derived pigments that resist solar radiation degradation, preventing yellowing or chromatic shift under prolonged direct sunlight.

High Load-to-Weight Ratio: Flexural strength exceeding 45 MPa allows for larger unsupported panel spans in ventilated facade sub-framing compared to traditional dimension stone.

Chemical & Atmospheric Resistance: Inert to acid rain, industrial pollutants, salt spray, and urban smog, preventing surface etching and staining.

Surface Finishes

Polished: High-gloss reflective finish (>50 gloss units) for striking visual depth.

Honed (Matte): Low-glare, satin-smooth texture (15–20 gloss units) suitable for monolithic architectural surfaces.

Bush-Hammered / Textured: Mechanical needle-hammered face providing slip resistance, tactile depth, and light-scattering properties.

Sandblasted: Fine-grained micro-textured finish for understated urban aesthetics.

Color Series

Solid Monochrome: Pure white, charcoal black, and industrial gray for minimalist facades.

Natural Veined: Continuous marble-look directional veins passing through the entire panel thickness, preventing exposure of uncolored cores during edge profiling.

Aggregate Exposed: Custom quartz grain distributions utilizing coarse regional quartz chips for heavy industrial or civic scale.

Rainscreen Ventilated Facades: Mounted via undercut anchors (e.g., Keil anchors) or visible clip systems on aluminum/stainless steel sub-frames, creating a thermal break and moisture drainage cavity.

Curterior Spandrel Panels: Non-vision glass replacement areas on high-rise commercial structures.

Column Cladding: Precision miter-folded or curved radius corner panels wrapping structural steel supports.

Exterior Soffits & Canopies: Overhead exterior applications requiring structural rigidity against wind suction forces.

Retail Storefront Portals: Heavy-traffic pedestrian ground-floor cladding resistant to impact and frequent cleaning chemicals.

Precision Cut-to-Size: CNC waterjet and 5-axis bridge saw cutting based on contractor DWG/DXF shop drawings, holding dimensional tolerances within ±0.5 mm.

Edge Processing: Factory-executed beveling, rabbeting, kerf cutting for clip attachment, and blind-hole drilling for undercut mechanical anchors.

Custom Color Matching: Laboratory spectrophotometer color matching for corporate identity requirements based on RAL or Pantone physical color chips (minimum batch quantities apply).

Backside Reinforcement: Application of alkali-resistant fiberglass mesh or high-strength epoxy backing films upon request for large-format panel installations.

Production Process

Raw Material Grading: High-purity quartz sand and granules are magnetically separated to remove iron impurities, preventing internal discoloration spots.

Batching & Dry Blending: Automated weight-cell dosing mixes aggregate fractions with resin and additives under strict vacuum conditions to eliminate air voids.

Vibro-Compression: Material is transferred into a vacuum press applying simultaneous hydraulic pressure (100+ tons) and multi-axis low-frequency vibration to achieve >99% compaction density.

Thermal Curing: Slabs undergo controlled catalytic thermal curing in a multi-stage kiln oven at 90°C–105°C to achieve complete cross-linking of the polymer matrix.

Calibrating & Finishing: Slabs cure for 48 hours before multi-head abrasive calibration, thickness leveling, and surface finishing.

Quality Control Protocols

Dimensional Inspection: Automated optical scanning measures diagonal squareness, thickness uniformity, and edge straightness on every slab.

Internal Integrity Testing: Ultrasonic pulse velocity testing detects internal micro-voids or delamination before fabrication.

Batch Retain Samples: Retained samples from each production shift are archived for 5 years for traceability and accelerated weathering audits.

Export Packaging: Fumigation-free vertical A-frames or horizontal heavy-duty wooden crates lined with EPE foam separation sheets to prevent transit abrasion and shock translation.

Container Loading: Secured with steel tension bands and dunnage bags inside 20-foot dry containers (maximum load limit 26,000 kg).
