UTILITY SPLIT SET HANGER BOLT (Friction Stabilizer Hanger)
UTILITY SPLIT SET HANGER BOLT
Split Set Utility Hangers can also make screen and mesh installation much easier, faster and safer. After your opening is secured with standard Friction Bolt, install the mesh all at once by driving friction bolt Utility hangers inside the tubes. No new holes are needed. There's no awkward handling of mesh at the end of a long bolt, or under unsupported ground. Screen or Mesh conforms to the rock more tightly.
Utility Hanger Bolt also need to be pull testing to be sure they could have the function of inserting into the present split set bolts and fixing tightly for hanging for fixing different things that maybe necessary or standard used in the ground support applications.
The profile of Utility Hanger Bolt is just same with Split Set Bolt and is made by the same rollformers and welders, so it has the same requirements with the split set bolts, and we follow the same standard and processes to make the Utility Hanger bolt.
Hanger bolt's welds quality is a also very critical point for the split set bolt which will affect the performance of the bolt while used in ground support. We have a routine quality mornitoring and warning system to get a consistance and stable perfect welds quality, and a job traveller with pull testing records will go through the whole processes to avoid any accidents in the production.
Hanger galvanizing and Black Split Set Bolt with different length are available. Made by high-grade of steel material, our split set bolt can get a very good zinc coating surface to have a better performance when it is used in corrosive environment.

FAQ of FB-39 SPLIT SET BOLT
1. What is Combi Plate and how does it make ?
Utility Split Set Hanger Bolt are also made by high tensile steel strip, which is same with the support bolt by roll-formed into a longitudinal slot C shape tube along its entire length. A steel ring is full welded on the end of the tube by automatic welding device, which is to drive into the present support bolts.
2. How to use and assemble ?
