Mining Roof Bolts Supply in South Africa

Songatech is a leading manufacturer and supplier of high-tensile Roof Bolts used extensively in underground mining operations to ensure structural integrity and tunnel safety. Our product catalogue includes a comprehensive range of support systems designed to hold rock layers together and prevent falls of ground, including Resin Anchored Rebar, Mechanical Anchor Bolts, Friction Stabilisers, and Cable Bolts. On this page, we explain in detail our roof bolt specifications and our supply capabilities across all major mining regions in South Africa.

Comprehensive Roof Bolt Catalogue

We provide various anchoring solutions tailored to specific rock mass ratings and geological conditions. From our base in Alrode, Alberton, we distribute these critical safety products to mining hubs in Rustenburg, Steelpoort, Middelburg, and Kathu.

Resin Anchored Rebar Bolts: These deformed bars use fast or slow-set resin capsules to create a strong, reliable bond for long-term support.
Mechanical Anchor Bolts: Featuring expansion shells, these are ideal for competent rock where immediate loading is required after installation.
Friction Stabilisers (Tube Bolts): These expansion tubes grip the borehole wall along its entire length, performing exceptionally well in squeezing ground conditions.
Cable Bolts: Multi-strand long anchors designed to bridge large spans at intersections, typically available in lengths from 3.0 m to 6.0 m.

Technical Specifications

Our roof bolts are manufactured to rigorous quality standards to ensure predictable behaviour in high-stress environments.

Ground Support Accessories and Quality Assurance

To ensure a complete safety solution, Songatech supplies all necessary accessories that work in conjunction with our bolting systems. This includes Oslo Straps, which are essential for securing hanging walls in high-pressure areas.

Plates and Washers: Domed and spherical washers to ensure even load distribution.
Mesh Sheets: Used alongside bolts to cover surface areas between support points.
Strict Quality Control: Every batch comes with steel grade certificates, and we perform regular tensile and pull tests on samples to guarantee performance.

Selection Guide for South African Mines

Choosing the correct support pattern is critical for workplace safety. We provide technical guidance to match the bolt type to your specific mine support rules:

Competent Rock: We recommend Mechanical Anchor Bolts (1.2 m to 1.8 m) for immediate load in development ends.
Jointed or Bedded Ground: Resin Anchored Rebar (1.5 m to 2.4 m) is best for general headings to ensure durability.
Squeezing Ground: Friction Stabilisers are the preferred choice for drives and crosscuts due to their superior along-hole grip.
Wide Intersections: Cable bolts used with Oslo Straps or mesh are required for large spans to limit block falls.
