Product Features

1. Lightweight Structure with a Stone-Like Surface

With a density of approximately 0.4 t/m³, lightweight microcrystalline stone places less load on the building structure than many conventional solid stone materials.

Its microcrystalline surface provides the appearance and texture of architectural stone, while the internal honeycomb structure helps reduce panel weight.

2. Thermal Insulation and Sound Reduction

Beneath the microcrystalline surface is a honeycomb foaming layer formed through high-temperature melting and foaming. The closed-cell ratio exceeds 75%, helping reduce heat transfer through the material.

Depending on the product configuration, its thermal conductivity ranges from approximately 0.076 to 0.15 W/(m·K). The structure can also provide sound reduction of up to 40 dB, subject to panel thickness, installation method, and the complete wall-system design.

3. Fire-Resistant Inorganic Material

Lightweight microcrystalline stone is produced from inorganic materials through high-temperature melting and sintering.

The material can achieve Class A reaction-to-fire performance and a fire-resistance duration of up to three hours, depending on the tested product configuration and applicable testing standard.

4. Integrated Surface and Core Structure

The decorative microcrystalline surface and honeycomb core are formed together through a high-temperature sintering process.

This integrated structure combines decorative appearance, reduced weight, thermal insulation, and structural performance in a single architectural panel.

5. Weather and Corrosion Resistance

The material contains approximately 60%–70% silicon, together with aluminum, calcium, boron, and other inorganic elements.

This composition contributes to dimensional stability and resistance to weathering, corrosion, acids, and alkalis, making the material suitable for exterior wall and façade applications when correctly specified and installed.

6. Recyclable Material Solution

The primary raw material is silicon-based solid waste that is processed and crystallized at high temperatures.

The finished material can be recycled, helping reduce raw-material consumption and supporting more sustainable building-material selection. Relevant environmental and radioactivity indicators should be confirmed through applicable product test reports.

Lightweight microcrystalline stone building external wall component form

The light stone exterior components are installed in the same way as the glass. Opaque Lightweight microcrystalline stone and transparent glass form the entire perimeter of the building. Therefore, there is an image of Lightweight microcrystalline stone called "glass companion".

Lightweight microcrystalline stone unit wall forms

including row window type, column type, free type and other external wall forms. Lightweight microcrystalline stone unit wall completely standard the current stone wall, is the basic unit of the complete stone wall made of Lightweight microcrystalline stone and supporting frame in the factory, according to the needs of the building height and the designer's design appearance and specifications, the combination of light steel embedment or back bolt, joint can be used in the form of silicone pointed or dense, industrial integrated manufacturing, The site is directly installed on the building structure, and the building outer protection and external decoration are all in place at one time, which greatly improves the construction efficiency and application reliability. Compared with the external stone wall, the comprehensive cost-effective advantage of the Lightweight microcrystalline stone unit wall is outstanding.

Lightweight microcrystalline stone prefabricated house

Light stone prefabricated housing is a new low-rise building product manufactured through industrial production mode, which starts from light stone composite wall material and combines with corrosion-resistant steel to form a light stone unit structure module. Lightweight microcrystalline stone features: safe and comfortable, convenient installation, such as the thick and solid texture of natural stone, the cost is controllable.

1. Convenient assembly method

a. Each module is assembled from basic elements (wall panels, floor panels, roof panels, etc.).

For the basic element composition: Each assembly module is pre-fabricated in the factory using standardized wall panels, floor panels, roof panels, and supporting connecting components (e.g., corrosion-resistant steel fasteners matching the material properties). These basic elements undergo strict quality inspection (such as size calibration, structural load testing) before leaving the factory, ensuring they meet direct on-site assembly requirements—no need for on-site cutting, welding, or other complex processing. During installation, workers only need to follow simple positioning and splicing procedures (similar to the "building block" method), and the modules can be quickly connected via pre-reserved interfaces, avoiding the mess of traditional on-site masonry or concrete pouring and significantly shortening the construction period (e.g., a 100㎡ single-story prefabricated house can be assembled in 3-5 working days).

b. The combination of high-precision modules can create different types of house construction

For high-precision module combination: Relying on the production process's strict dimensional control (module size error ≤ 0.5mm), the high-precision modules have excellent compatibility and fit. This allows them to be flexibly combined according to architectural design needs—whether it is low-rise residential buildings (e.g., villas, courtyard houses), small commercial spaces (e.g., community convenience stores, rural service centers), or even special-scene buildings (e.g., temporary disaster-resilient housing, scenic area supporting facilities), the modules can be adapted to different floor heights, plane layouts, and exterior styles. For example, combining wall panels with different microcrystalline stone surface textures and roof panels of different slopes can create both modern minimalist and rural-style buildings, breaking the limitations of traditional single-material construction forms.

2. High-precision fabric specifications - surface flatness < 2mm

The lightweight microcrystalline stone's "surface flatness < 2mm" is not only a numerical indicator of manufacturing precision but also a core guarantee for its subsequent application effects, achieved through a combination of advanced production processes and strict quality control, and brings tangible benefits to construction and use:

How high precision is achieved: During production, the silicon-based solid waste raw material is first ground into micro-powder with uniform particle size (particle size error < 10μm) to ensure uniform material distribution; then, through "dry powder laying + high-temperature crystallization foaming" technology, the temperature is controlled with an accuracy of ±5℃ to avoid uneven expansion caused by local overheating; finally, the surface is polished by a fully automated precision grinding machine (grinding head rotation speed up to 3000r/min, grinding path planning with computer numerical control) to eliminate tiny surface defects and ensure that the flatness of any 1㎡ area on the surface is less than 2mm.

Practical value of high precision: On the one hand, it simplifies subsequent construction—since the surface is already ultra-flat, there is no need for additional plastering, leveling, or other processes during on-site decoration, saving 20%-30% of the decoration time and reducing the cost of auxiliary materials (e.g., putty, cement). On the other hand, it enhances the building's aesthetic and structural stability: the ultra-flat surface makes the microcrystalline stone's natural texture more uniform and bright, avoiding the "uneven color" or "wavy surface" caused by poor flatness; at the same time, the uniform flatness ensures that the force is evenly distributed when the modules are assembled, reducing the risk of local stress concentration and deformation, and extending the service life of the building.

What are the thickness range and maximum size of the Lightweight microcrystalline stone?

Its thickness is 5mm to 10mm, and the standard maximum size is 1200mm x 1800mm. Custom sizes are also available upon request.

How does its thermal insulation performance compare to traditional glass?

Its thermal conductivity is 0.076-0.15W/m·k, and the insulation effect is better than that of three-glass two-cavity low-E insulated glass.

Can the Lightweight microcrystalline stone be installed like conventional building materials?

Yes. Its exterior components are installed the same way as glass; for unit walls, they are prefabricated in factories (with frames) and directly installed on building structures on-site, improving construction efficiency.

What is the delivery time for this product?

The standard delivery time is 14 days after order confirmation.
