Stone Honeycomb Panel

Introduction

Natural stone honeycomb panels are an advanced energy-saving and environmental-friendly building slab composed of an aluminum honeycomb backing and a stone veneer panel with a thickness of 1-10mm. The original surface material pieces are split into halves and sometimes thirds, then composited with other materials to significantly reduce weight, allow a large panel dimension and improve the stone strength.

SYSTEM COMPOSITION

Veneer panel: 1-10 mm stone

Backing: 5-20 mm aluminum honeycomb panel or FRP honeycomb panel

Total thickness: 6-30 mm

Size: 1600 * 3200 mm (limited by the size of stone l)

Adhesive: aviation grade epoxy resin in an exclusive formula, with an excellent freeze-thaw test performance and long service life in an outdoor environment

Interlocking clip: aluminum or stainless steel installed by a high-precision CNC process

ADVANTAGES

As a decorative material, natural stone is generally expensive, and has natural defects such as a heavy weight, unstable physical structure and color difference. However, Aluwedo’s natural stone honeycomb panel has some special advantages compared to traditional stone. Natural stone veneer on aluminum honeycomb panels increases the raw material usage area in practical applications, thus greatly cutting down the weight, reducing the color difference in the stone, improving the physical structure of the stone, and significantly increasing installation convenience through interlocking clips, which also widens the stone application scope, such as cladding in high rise buildings.

COMPARISON OF STONE HONEYCOMB PANELS WITH TRADITIONAL STONE SLABS

Comparison Item	Traditional Stone Slabs	Stone Honeycomb Panels
Weight	30mm total thickness, about 75kg/㎡	20mm total thickness, about 15kg/㎡
Flexibility	Unable to bend	Bendable; no cracking after 30mm bending test
Installation Cost	High installation cost	Lower installation cost, about 100 yuan/㎡
Safety Performance	May crack during impact-resistance testing	Only slight punctate cracking during impact-resistance testing
Material Utilization	Limited usable material output from one cubic meter of stone	Approx. 80–100㎡ usable panel output from one cubic meter of stone
Maximum Size	≤600×600mm	Up to 1600×3200mm

The core of stone honeycomb panel is done through both a composite process and the splitting process. With the combination of the two processes, a piece of standard 2cm thick stone can be split into two panels with a similar thickness, resulting in a stone composite panel with double the available area. Similarly, if a 3cm thick stone slab is split and composited, you can get four times the available area. Moreover, this process reduces color differences in the stone, saving the cost per square meter for middle-to-high-end stone materials because less stone is used. The light weight (about 20% of the original weight), heat insulation and soundproofing characteristics of the stone honeycomb panel assist in improving the environmental protection index and energy-saving indicator of buildings and improve noise pollution.

BENDABLE STONE HONEYCOMB PANEL

The bendable natural stone honeycomb panel developed by Aluwedo consists of a 1-2 mm stone veneer panel and aluminum honeycomb backing. The special technology used in this panel has been awarded a national patent and continuously optimized in projects over the past few years. The current accuracy of finished bendable panels reach within millimeter tolerances.

Compared with the traditional curved stone panels processed by cutting, the bendable stone panel has a larger surface, is energy-saving, environmentally friendly, easy to install, and more economical due to the reduced stone usage.
The bendable natural stone honeycomb panels feature a wide application range. For stones with a low brittleness, the minimum bending radius is 600mm; for stones with a high brittleness, the minimum bending radius is generally 1000mm.

PANEL SELECTION

Aluwedo offers more than one hundred different selections of natural stone panels, such as marble, granite, sandstone, quartz stone, artificial stone, and more, all of which are perfect for both interior and exterior applications.

We also have corresponding adhesive formulations and composite processes for stones with different characteristics to reduce the scrap rate.
