Research & Development Advantage
Stone is a natural material: porosity, hardness and mineral composition differ from batch to batch, and experience alone cannot hold quality steady. Hengsheng runs an international stone art research centre where architects, geologists and materials engineers translate the behaviour of each stone into measurable process parameters — from sealer penetration depth to polishing head speed, every setting is backed by test data.
Core Strengths
- Cross-disciplinary team: mineralogy specialists, international building-materials engineers, architectural designers and environmental researchers work in one room, aligning design language, materials science and production reality.
- Deep-penetrating nano protection: the sealer penetrates the capillary structure to form a hydrophobic layer, raising stain resistance roughly significantly against untreated stone while leaving colour and breathability untouched.
- Data-driven process parameters: polishing pressure, head speed and resin ratios are continuously corrected against SGS third-party testing, so gloss, water absorption and abrasion resistance stay within one band across batches.
- Joint academic validation: partnerships with Politecnico di Milano, Tsinghua University School of Architecture, the University of Hong Kong Department of Architecture and a key laboratory under the Ministry of Natural Resources covers weathering mechanisms, radionuclide limits and sustainable mining.
Key Figures
Service Process
- Topic defined: raised by market feedback, site problems or a bespoke client requirement.
- Baseline testing: samples drawn from different quarries and batches for absorption, compressive strength, abrasion and staining.
- Process trials: polishing parameters, sealer formulation and resin treatment adjusted, with comparison panels produced.
- Third-party verification: sent to SGS and others for testing to international standards, producing citable reports.
- Line rollout: parameters frozen into work instructions, operators trained, then reviewed on a continuing cycle.
Applications
- Countertops and food-preparation areas in hotels and restaurants needing stain and acid resistance
- Coastal or high-humidity facades and curtain walls requiring salt-spray and weathering resistance
- High-traffic retail flooring with strict abrasion and slip requirements
- Art installations and bespoke furniture with specific surface texture and touch
Sustainability & Certification
Development is framed by environmental priorities: water-based sealers replace solvent formulations to cut volatile organic compound emissions, with interior products certified to GREENGUARD Gold for low VOC release and NSF/ANSI 51 for food-contact safety.
Process upgrades cut energy and loss at the same time — protection and resin treatment raise yield, and with rooftop solar plus 95% water recycling the carbon footprint per square metre falls year on year.
Deep Selection Guide
Research capability shows up in whether a supplier can state the numbers: water absorption, abrasion resistance, the measured gain in stain resistance — all backed by third-party reports rather than touch and experience alone. Work backwards from the application: kitchens and food service look first at staining and food-contact safety; coastal projects at salt spray and weathering; heavy-traffic floors at abrasion and slip class. Ask for the matching test reports and samples before ordering, confirm whether sealer treatment is included in delivery, and how often maintenance is required.
- Selection criteria：The conditions of use at Countertops and food-preparation areas in hotels and restaurants needing stain and acid resistance dictate the stone and the process, while Cross-disciplinary team governs how the finished face reads; only when both are settled should an order be placed.
- Specification & thickness：Control tolerance with Measured positioning accuracy (≤0.1mm) and set panel size to Coastal or high-humidity facades and curtain walls requiring salt-spray and weathering resistance; corners and cut-outs must be called out on the detail drawing beforehand.
- Acceptance & records：Acceptance focuses on Deep-penetrating nano protection: the sealer penetrates the capillary structure to form a hydrophobic layer, raising stain resistance roughly significantly against untreated stone while leaving colour and breathability untouched., with figures and images retained; if a dispute arises it can be traced by batch code back to production and testing.
- Sustainability：Development is framed by environmental priorities: water-based sealers replace solvent formulations to cut volatile organic compound emissions, with interior products certified to GREENGUARD Gold for low VOC release and NSF/ANSI 51 for food-contact safety. Set it out in the contract and acceptance documents, and bring it into line with local environmental rules.
On Research & Development Advantage, the value Hengsheng brings is not the material alone but whether selection, fabrication, QC and delivery can be closed into an auditable loop that keeps programme and quality under control together.
FAQ
- Does nano protection change how the stone looks?
- Deep-penetrating sealers form a film inside the capillaries rather than a visible surface coating, so colour and veining are unchanged and the stone stays breathable. Treated surfaces resist staining about eight times better and need only water or a neutral cleaner in daily care.
- How do research results reach the production line?
- Every improvement passes sample testing, comparison panels and third-party verification before the data is frozen into work instructions. Production and inspection staff are trained on the change, and results are reviewed afterwards to feed the next iteration.
