GSD is a special anchoring system for stone cladding.It allows an hidden fixing on the back of the stone slabs with very high safetyfactors against pull-out failure. The main features of the GSD fixings are:

NO INTERNAL STRESSES IN THE BASE MATERIAL (STRESS-LESS ANCHOR), THEREFORE IT ALLOWS HIGH SAFETYFACTORS OF THE FIXINGS

VERY EASY AND FAST INSTALLATION WITH PNEUMATIC TOOL

IT CAN BE DIRECTLY INSTALLED IN THE WORKSHOP BECAUSE THERE ARE NO PROJECTING PARTS FROM THE SLAB SURFACE,THEREFORE THERE ARE NO PROBLEMS FOR PACKING AND SHIPPING

RECOMMENDED FOR SAFE FIXINGS UNDER HEAVY LOADS, SPECIALLY FOR THIN MATERIAL THICKNESS

FAST AND EFFECTIVE FOR ASSEMBLING WITHOUT USE OF ADHESIVES
