Official SGS Test Report: Surface Density of Flexible Stone Reaches 3.96 kg/m²
Meta Description :
Discover the official SGS test report for our Flexible Stone. With a surface density of only 3.96 kg/m², it is the ultimate lightweight solution for safe and compliant Facade Retrofit projects.
1. Report Overview
This article presents the official SGS test report (Report No. GZIN2509001820CM01-1_EN) evaluating the surface density of our Flexible Stone. Conducted by SGS-CSTC Standards Technical Services Co., Ltd. (Guangzhou Branch), the test confirms that our 2.0mm thick material achieves an ultra-lightweight surface density of 3.96 kg/m².
As a core benchmark in Flexible Stone Engineering, this data proves the material’s exceptional lightweight properties, making it an ideal choice for high-rise urban renewal and Facade Retrofit applications.
2. Data Analysis: Why 3.96 kg/m² is a Game-Changer
According to the test results, the Flexible Stone (Specimen: 100mm × 100mm × 2.0mm) has a surface density of 3.96 kg/m².
To understand the significance of this data, we must compare it with traditional building materials:
- Traditional Natural Stone (20mm-30mm): Typically weighs 50 to 80 kg/m².
- Conventional Ceramic Tiles: Typically weighs 20 to 30 kg/m².
- Fortune Stone’s Flexible Stone (2.0mm): Only 3.96 kg/m².
Engineering Value for Facade Retrofit:
In Facade Retrofit projects, structural load-bearing capacity is a major constraint. Traditional stone cladding often requires additional steel reinforcement, which drastically increases costs and construction time. With a density of merely 3.96 kg/m², our Flexible Stone can be directly applied to existing exterior walls without increasing structural load, ensuring maximum safety and significantly reducing overall project costs.
3. Test Methodology
The SGS evaluation was conducted strictly under the Chinese national standard GB/T 29059-2012 (Section 7.4), which specifies the testing methods for ultra-thin stone composite panels.
- Test Standard: GB/T 29059-2012 Section 7.4
- Specimen Size: 100mm × 100mm × 2.0mm
- Test Condition: The sample was measured under standardized laboratory conditions to determine the mass per unit area.
- Test Result: 3.96 kg/m² (Pass)
Note: The test report explicitly states that it is intended for internal quality control and product research & development. For official bidding or compliance verification, the specific SGS report number should be referenced.
4. FAQ
Q1: What does a surface density of 3.96 kg/m² mean for my project?
A: It means the material is extremely lightweight. For Facade Retrofit projects, this eliminates the need for heavy structural reinforcements. You can renovate old buildings quickly and safely without worrying about the original wall’s load-bearing capacity.
Q2: Does this report apply to all thicknesses of your Flexible Stone?
A: No. This specific SGS report (GZIN2509001820CM01-1_EN) tests a 2.0mm thick specimen. While thickness slightly affects the overall weight, the core lightweight advantage remains across all our product lines. For specific data on other thicknesses, please contact our technical team.
Q3: Why is lightweight cladding better than traditional stone for high-rise buildings?
A: Traditional stone is heavy and prone to detachment if the adhesive fails under stress. Flexible Stone weighs less than 4 kg/m², drastically reducing the risk of falling hazards and ensuring compliance with strict high-rise building safety codes.
Q4: Is this test report available for download?
A: The SGS report is intended for internal reference and R&D purposes as stated by SGS. However, you can verify this data using the SGS Report No. GZIN2509001820CM01-1_EN or contact our sales team for official certification documentation during the procurement process.
