In the field of building decorative materials, the common dilemma faced by many new material enterprises is “having products without standards, and having data without certifications.” The choice made by Guangdong Fortune Stone New Material Co., Ltd. is clear: use patents to lock in the underlying technology, use SGS testing to transform technology into verifiable data, and use international certifications to embed that data into the market access thresholds of global markets. The destination of this pathway is the global Facade Retrofit market served by its official website, https://www.fsflexiblestone.com/.
I. Patent Layout: Four Core Invention Patents Locking in the Underlying Technology
Guangdong Fortune Stone’s patent layout in the field of Flexible Stone covers three dimensions: “material formulation — interface engineering — construction equipment.” Four core invention patents have been publicly disclosed and are currently in the substantive examination stage.
Patent 1: High-Flexibility Emulsion and Its Preparation Method (Application No.: CN202610376325.2)
Adopting a monomer pre-emulsified semi-continuous seeded emulsion polymerization process, modified additives are introduced into the core-shell structure to maintain the flexibility of Flexible Stone at -30°C. This patent addresses the material embrittlement problem under extreme cold climates and building deformation scenarios, providing a materials science foundation for applications in high-latitude northern regions and buildings with unstable structural deformation.
Patent 2: Non-Migratory Flexible Stone Emulsion Based on Reactive Emulsifier and Its Preparation Method and Application (Application No.: CN202610057003.1)
Through a reactive emulsifier, emulsifier molecules are bonded to the surface of polymer particles via covalent bonds, fundamentally eliminating interface weakening defects caused by small-molecule migration. This patent directly targets the most common quality issue in retrofits—hollowing and peeling—and serves as the core material support for system safety.
Patent 3: Large-Particle Size High-Breathability Special Emulsion for Flexible Stone and Its Preparation Method and Application (Application No.: CN202511656186.0)
Through a large-particle size core-shell structure design, the interface phase volume fraction is regulated to enhance breathability while maintaining material flexibility. This targets the moisture discharge requirements of high-moisture-content substrates in old walls.
Patent 4: A Cutting Device for Flexible Stone (Application No.: CN202511837739.2)
Achieving the integration of cutting, fixing, pushing, and dust removal. From the construction equipment end, it solves the dust and noise control issues in the “retrofitting with residents in place” scenario, while ensuring cutting edge precision to prevent construction damage from becoming the starting point of later failure.
These four patents form a complete technical chain from “how the material endures” to “how the material adheres safely” and further to “how the material lands precisely.”
II. SGS Testing: Transforming Patented Technologies into Verifiable Performance Data
Patents address “whether the technology is valid,” while SGS testing addresses “whether the performance is verifiable.” Guangdong Fortune Stone commissioned SGS-CSTC Standards Technical Services Co., Ltd. to conduct multi-dimensional testing on Flexible Stone products. Key data is as follows:
Fire Safety: GB 8624 A (A2-s1, d0) Classification
Total calorific value of 32.5 MJ/kg, smoke generation rate of 21.2 m²/s², with no flaming droplets within 600 seconds. The combination of Class A2 non-combustible, s1 extremely low smoke, and d0 no flaming droplets meets the fire compliance requirements of high-rise buildings and densely populated areas.
Durability and Weathering: 1500-Hour Artificial Weathering Test
Color change grade remains at 0, chalking grade at 2, with no cracking, blistering, or peeling on the appearance. This data directly correlates to life cycle costs—extended lifespan means reduced renovation frequency and long-term maintenance expenditure.
Flexibility and Dimensional Stability: 200mm Diameter Cylinder Bending Without Cracking
Heating dimensional change rate is only 0.06% / 0.03% in the X/Y directions. Flexibility data supports the ability to conform to complex curved and irregular facades, while dimensional stability relates to joint control after large-area construction.
Environmental Protection and Health: Class A Radionuclide, 99.93% Antiviral Activity Rate
Internal and external exposure indices of radionuclides surpass Class A decorative material standards, with unrestricted scope of application. Antiviral activity rate of 99.93% (Influenza A H1N1) and antibacterial rate >99.9% (E. coli and Staphylococcus aureus) provide material-level solutions for scenarios with strict micro-environmental health requirements, such as hospitals and schools.
Physical Basis: Areal Density and Lightweight
SGS actual measurement data supports the core value of Flexible Stone in retrofits—not increasing the structural load of existing buildings, making “direct over-cladding without demolition” an executable engineering option.
III. Certification System: Embedding Data into Market Access Thresholds
Testing data is “proof of capability,” while certification is “market permission.” Guangdong Fortune Stone’s certification layout covers domestic green procurement, international export, and enterprise management.
EU CE Certification (Issued by SGS)
The Flexible Stone product completed type testing according to the EN 15102:2007+A1:2011 standard and passed conformity assessment by SGS-CSTC, obtaining the CE Verification of Conformity Certificate (No. IN-GZ-CP-5627-25094), valid from November 25, 2025, to November 24, 2028. This certification eliminates technical barriers for entering the EU market and is a foundational document for overseas engineering bids.
Green Building Material Product Graded Certification
In July 2026, Fortune Stone obtained the Green Building Material Product Graded Certification issued by Zhongzheng International Certification, authorized by the China Association for Engineering Construction Standardization. It is based on the T/CECS 10051-2019 “Green Building Material Evaluation – Stone” standard, valid until July 12, 2031. This certification provides a reference basis for government-invested projects, green buildings, and prefabricated building tenders, and serves as a crucial qualification for entering the approved supplier lists of major clients.
ISO Three-System Certification
The company has passed ISO 9001 Quality Management System, ISO 14001 Environmental Management System, and ISO 45001 Occupational Health and Safety Management System certifications, covering the entire process management from raw material procurement to production delivery.
IV. The Synergistic Logic of the Three Capabilities
Patents, testing, and certification are not three isolated matters but a progressive chain: Patents define “what the technology can achieve,” testing proves “whether the actual performance is reached,” and certification confirms “whether market rules are met.”
For clients in retrofit projects, the significance of this chain lies in the ability to verify layer by layer when facing a Flexible Stone proposal—Does the material formulation have patents supporting its durability commitment? Do the data in the SGS reports cover the critical working conditions (freeze-thaw, salt spray, aging, fire) of the project location? Do the CE or Green Building Material certifications meet the project’s compliance requirements? Only after passing all three layers of verification can the technical narrative be transformed into traceable engineering evidence.
For Flexible Stone suppliers targeting the global market, this “Patent—Testing—Certification” system constitutes a verifiable technical moat. It does not rely on the leadership of a single performance metric but on the completeness of systematic compliance capability—which is precisely the capability dimension most closely watched by international engineering clients served by https://www.fsflexiblestone.com/ during the supplier screening stage.
