concret wood stone Cement and aggregate are the primary materials. Application of lightweight compound materials technology has yielded higher strength and better freeze-thaw properties allowing the stone veneer to be applied in extreme conditions. Our investment into R&D empowers us to provide creative ideas to work with architects and designers. Size specifications are: Antique plank board 900*200mm; Modern board 1000*150mm; Old board 900*100mm. Merit: 1.They can be used instead of natural wood.Because their texture and color are as same as natural wood.2.What's more,they keep well nel sole e nel vento la mia festa outdoors.3.Overall they have constant shape and quality,also are antiseptic and mothproofing.4.In the condition of using cement wooden board,you should install them firmly by cement mortar or glue for tile. 5.It can withstand more than 20 years around bad environment.Physical index:1.Exact replicas of natural stones capture the texture and color of real stones with specific colors being an optional design choice.2.Low water absorption (17.2%) supports direct use for exterior walls.3.High bending strength (3.4 Mpa) provides a secure and durable core covered by an especially high strength (12.8 Mpa) exterior face.4.Low shrinkage (<0.5mm/m), no crevasse cracks.5.Good freeze-thaw properties allow the stone veneer to be applied in extreme conditions.6.Low density only half that of natural stone facilitates easy installation and reduced transportation costs.7.Free of harmful radioactivity; pigment is lead-free.Project
