This anchoring system has been developed for use in suspended roofs so that a metallic anchoring system made from steel rods is available for monolithic additions. The anchors are hung over pipes and tied into position using a wire. When used in turn the HAR and HAL anchors result in a cross-shaped pattern. By this way roofs can be anchored excellently. It goes without saying that anchors can be supplied on request to fit pipes with different diameters.
