Description:
Dry hanging stone curtain wallGranite Surface Finished
Polished, Flamed, Antiqued, Bush Hammered, Sandblasted, etc
Construction of dry-fasten stone onexternal wall
Construction of dry-fasten stone on external wall
It is widely used for projects in Northern China which havecold weather.
Project adopts New Type of dry-fasten stoneon external wallwithout welding. light weight, high strength, fastinstallation and high cost performance. Super-low K value is agreat selling point to make builders in various regions to selectthis material.
