Limestone Honeycomb Core Material Panel For Indoor Decoration , 25 Mm Thickness
Product Description
High Strength Limestone Honeycomb Core Panel is a sandwiched composite structure with an aluminium honeycomb panel and very thin limestone veneer. Its advantages includes light weight, limited radiation pollution, stone material saving, broader size and so on. The mainly application fields are ceiling, curtain wall, indoor wall panel, floors etc, which are being more and more widely used on the decoration and renovation of the industries of construction, vehicles, ships, etc.
General Description
The ultra-thin stone honeycomb composite panels are innovated because of the limited natural stone resources and its application restrict. It is a new type of building materials with a better impact resistance than the ordinary natural stone is with a weight of only 16 kg, is only 1/6 of the weight of its original natural stone slide but the compressive strength is 6 times more than the original stone slices. Completely overcomed the natural stone’s defects on weight, fragile and other aspects, it provides a more superior performance and wide application field as a new generation building material. Ultra-thin stone honeycomb composite panel is simply bonded with an about 3mm ~ 5mm thick stone sheet and an aluminum honeycomb substrate with a special purpose adhesive. It not only saves the stone material and reduces the weight of finished products, but reflects better in the stone effect. Based on these, there is a large demand from the market.
