Precision cut-to-size dimensional granite with ultra-low water absorption, tailored for high-traffic public works and extreme tropical environments.
Addressing rigorous micro-climates, coastal salinity, and seismic resilience across the Greater Metropolitan Area (GAM) and coastal tourism corridors.
Costa Rica experiences seasonal precipitation exceeding 3,000 mm annually. Porous limestones and low-density volcanic tuffs experience accelerated biological growth, mould, and structural spalling. Dense Chinese Grey Granite (density ≥ 2,620 kg/m³) ensures zero water retention and superior long-term cleanability.
Under the Costa Rican Seismic Code (Código Sísmico de Costa Rica - CSCR), multi-story commercial developments in San José and Heredia demand lightweight yet mechanically robust curtain wall panels. Precision-calibrated 30 mm G3743 Lu Grey and G654 granite meet stringent flexural yield thresholds under dynamic stress.
Guanacaste’s luxury resorts require exterior pool decks, steps, and boardwalks that endure extreme UV index exposure and marine salt air. Flamed and bush-hammered Sesame Grey finishes provide non-slip safety (R11/R12 ratings) without surface discoloration or efflorescence.
Eliminating intermediate brokerage markups through automated fabrication, integrated maritime routing, and batch-level quality control.
By controlling independent quarry concessions in Shandong and Fujian, Haichen Stone guarantees uniform color consistency, grain dispersion, and zero vein divergence across projects extending beyond 50,000 square meters of paving and facade panels.
Our intelligent automated workshops run computerized gang saws achieving dimensional tolerances within ±0.5 mm. Automated flame-finishing stations deliver homogeneous surface roughness (DIN 51130 certified) with zero thermal micro-fracturing of the quartz crystalline lattice.
Containers are loaded directly at Rizhao port facilities. All solid wood crates undergo certified ISPM-15 heat treatments and fumigation, equipped with desiccants and moisture-barrier film to safeguard against condensation staining during trans-Pacific sea transit.
Independent laboratory validation confirming optimal mechanical resistance for architectural specifiers and civil structural engineers.

Tailored dimensions and specialized surface textures engineered for municipal, hospitality, and corporate environments.
Multi-story financial facilities in Escazú and Santa Ana utilize honed 600×600×20 mm G614 Sesame Grey for interior atriums, paired with flamed exterior pedestrian walkways to preserve slip safety during sudden tropical afternoon downpours.
Ultra-luxury coastal developments in Guanacaste leverage G654 Sesame Grey flamed coping around infinity pools, private terraces, and beach club boardwalks, where salt spray would compromise travertine, marble, and composite woods.
Heavy-duty logistics terminals and arterial access routes depend on calibrated 150×300×1000 mm G3743 Lu Grey natural split curbstones, capable of withstanding constant 40-foot container truck side-impact and cyclic dynamic axle friction.
Empowering Costa Rica's National Decarbonization Plan through circular stone manufacturing and clean fabrication technology.
Our grey granites contain zero VOCs, synthetic resins, or petroleum binders. When specified for exterior facades and shading envelopes, their thermal mass dampens peak cooling loads across Costa Rica's tropical lowlands, lowering building Energy Use Intensity (EUI).
Haichen Stone’s modern production lines operate fully closed-loop sedimentation and filtration units. Over 98% of process water is clarified and recycled back into multi-blade block cutters, drastically cutting water consumption during quarrying and processing.
To reduce freight carbon intensity and domestic customs processing overhead for Costa Rican contractors, we offer unified container stuffing combining structural granite pavers, architectural curtain wall steel fittings, and matching glass hardware.
Clear technical protocols, customs clearance criteria, logistics routes, and installation recommendations.
Quarry-direct slabs, specialized finishes, and complementary dimensional stone for large-scale developments.
