Product Details

Description

The hexagonal nuts are made of high strength steel with properly made by all edges to satisfy the demands of anchor specifications and other operations.

Application

Slope stabilization
Self-Drilling Anchors are very suitable for weathered or un-consolidated rock stabilization. This technique is a more superior form of stabilization because the SDA technique is a relatively easy and fast method of installation compared to the outdated methods.
Foundations with micro piles
SDAs can be used like monopoles and micropile types because these are drilled piles composed of steel reinforcement with injected grout. These anchors are used like micropile type to stabilize the ground and related foundation problems. These anchors are suitable for tension and compression loads at varying ground conditions.
Tunneling
Self-drilling anchors are most suitable for the stabilization of tunnel strengthening works. Mostly for the soft rock and overburden soil conditions, the SDA’s are apt for rooftop protection.
