The Etanco group's solution was to supply a whole set of mechanically welded stainless steel parts with articulated arms thus enabling the stone to tilt into a lintel. Our BARACO range of anchors as well as our ISOLCO range of brackets have been chosen and supplied for their high resistance to corrosion, which is essential in a large city subject to pollution.
