Product Description:
Minetech hollow bars are fully threaded self-drilling system that allows drilling into loose or collapsing drill holes with a system combined of grouting and anchoring simultaneously with no need for casing. Our hollow bars are made of high-grade steel and designed to meet ASTM and EN Standards.Our anchor bars are both available in R thread and T thread, selected raw material and a fully automated production system make the SDA system exceed the quality and proof of Yield and Tensile load.
Features:
1. It can solve defects that unfilled grouting of traditional mortar anchor bolt during the construction and can’t grouting with pressure.
2. The operation is simple, cost is low, construction is convenient and efficiency is clear.
3. It can realize grouting with pressure and reform foundation surrounding rock conditions.

Applications:
Self drilling anchor system is mainly used in slope stabilization, tunneling pre-support, foundations with micropiles, it is also widely used in the railway system, metro project etc. It can be installed in sites with weak rocks, loose soil, weathered layer, sand with stone layer and so difficult to create a hole in complex formations. The unconsolidated ground condition favor the self-drilling anchor bolt technique for fast and simple method of installation compared to the traditional method.
Packing and Shipping:
Packed in Carton or Wooden Box.
Sample will be sent by Fedex, shipping time 7-10days, main order will be shipped by sea.
