Choosing the Best Self-Drilling Anchor Manufacturers

Hollow bar anchors are commonly used in civil engineering. In recent years, especially after the acceptance by the EU and FHWA in the Micropile and Soil Nail Design and Construction Guidelines Manual, Self-Drilling Hollow Anchor Bars are being used increasingly for micropile applications.

There are many valuable qualities and features to consider when searching for the best hollow bar (SDA, IBO) suppliers in your area. The following points would be helpful when you are making a decision.

Brand of the hollow bar anchors

The brand reputation is a mirror of products and service. The reputation of an anchoring manufacture can be estimated by the local market feedbacks. After all, no one would use a fragile anchor bolt. And for infrastructure engineering, safety always comes first. The toll to a brand would be heavy if once an accident appearing. A glorious history can't reflect nowadays, but at least it can tell something is referable.

Tests reports of hollow bar anchors

All foundation stabilization, repair or any other commercial projects are particularly planned by designers. Any engineers and purchasers should acquire the necessary products with product suppliers.

The EU and FHWA have put forward the standards of soil nail and micropiles. The following technical parameters should be checked:

Strength

Ductility

Bending test

Even for the rock bolts applied in mining and tunneling, these performances are important because it related to the installation work and reinforcement result. It is obviously unqualified if a self-drilling anchor bolt is broken off while drilling and grouting. So don't ignore the ductility!
