Split sets are a type of support system used in underground mining and tunnelling to provide stability to the walls of the excavation. They are made of strong, durable materials such as steel and are installed in a pattern along the walls of the tunnel to provide support.
Our friction bolts are made of high-grade steel and are specially designed to ensure maximum anchoring strength. Each bolt is carefully manufactured and tested to meet strict quality standards, ensuring that our products are reliable and long-lasting.
Material: Carbon Steel
Norminal size: 33mm, 39mm, 46mm and 47mm diameter
Advantage:
1. It provide seamless support for rock and soil formations. The system uses a special anchoring technique to provide full-column grouting and helps to ensure that the bolt remains tightly in place throughout its lifespan.
2.THE INSTALLATION OF SPLIT SETS IS A QUICK AND EASY install.
Installing split sets is a relatively quick and easy process, and they can provide a high level of support with minimal equipment. However, it is important to follow proper safety procedures and guidelines when installing split sets to minimize the risk of accidents or
Injuries.
3.No anchoring agent required;
4.Environmentally friendly. They are designed to withstand harsh weather conditions and resist corrosion, reducing the need for frequent replacements and helping to lessen the environmental impact of construction projects.

Using Method:
1. Determine the anchor bolt hole position according to design requirements and use drilling tools to drill holes.
2. Blow out the rock powder inside the hole with compressed air.
3. Install an anchor plate on the rod and use an impact drill to drive the anchor rod into the hole.
Package:
Split sets are palletized on wooden bearers and bound with steel straps.
