Self-cutting anchor bolt

Product Description

Application:
·Curtain Walls
·Steel structures
·Staircases
·Escape platforms
·Machinery, conveyor systems, storage systems
·Collision barriers, noise walls
·Rail transport, road and bridge

Advantages:
·Expansion stress is small, allowing for small margins and small spacing.
·Stable and excellent anchorage performance under high loads and vibration loads.
·Epoxy resin reinforcing adhesive has passed GB50367 Grade A adhesive certification, which provides more stable and long-lasting performance under harsh environments.

Function:
·Suitable for pre-insertion installation, penetration installation.
·When the nut is tightened, the screw vertebrae squeeze the colloid, creating an expanding squeeze against the borehole wall.

Material:
·Electro Galvanised Steel
·Hot-dip galvanised steel
·Stainless Steel

Substrate:
·Cracked concrete/non-cracked concrete

Type test:
·2 million times fatigue test
·2 hours fire resistance test
·Seismic test
