Product Description

Grade of screw strength: Stainless steel A***0, A***0

Applicable for : Back-hung curtain wall system

Range of use: 1.Natural stone; 2.Artificial stone; 3.Ceramic plate; 4.Artificial fiber plate

1. Pre-insert post-undercutting stress-free aseismatic anchor bolt, has passed the seismic test of 9 grade fortification in National Center for Quality Supervision and Test of Building Engineering.

2. Anchor bolt dilatant is a sequential structural plane, when the dilatant is expanding, the lower diameter expands while the upper diameter minishes. At that moment, the shape of anchor bolt diatant is changed from cylindrical surface to circular conical surface.

3. The radius of dilatant conical equals to the radius fo the stone bottom cutting hole conical surface , and the two curved surfaces form unstressing concentric curved surface engagement;

4. Conical area meshing of the dilatant and the drill hole awards better pressure resistance of the fixing than point meshing of other similar products in the market.
