Oslo Straps Supply in South Africa

Songatech is a leading manufacturer of Oslo Straps, high-tensile steel support systems designed to work in conjunction with roof bolts to secure rock surfaces in underground mining. Our Oslo Straps create a continuous support line across the roof, effectively spreading the load between bolt heads and reducing the risk of slab or block falls. On this page, we detail our Oslo Strap specifications and our capacity to supply mining operations throughout South Africa.

High-Tensile Oslo Strap Catalogue

We manufacture Oslo Straps that bridge the gaps between bolt patterns, making travelling ways and intersections significantly safer. From our facility in Alrode, we supply these essential ground support products to major mining sectors in Rustenburg, Steelpoort, Middelburg, and the Northern Cape.

Flat Oslo Straps: Featuring a flat profile and slotted holes, these are ideal for general headings and match common bolt spacings.
Profiled or Curved Straps: These provide extra stiffness for uneven surfaces and longer spans, making them the preferred choice for wide intersections.
Heavy Duty Straps: With increased thickness for high-load zones, these straps are engineered to work with cable bolts and dense bolting patterns to keep panels stable.

Technical Specifications

Our Oslo Straps are built for durability and precision, ensuring they meet the high-tensile demands of deep-level mining.

Feature	Specification Details
Material	High-tensile steel strap
Standard Widths	100 mm to 150 mm
Thickness Range	3 mm to 6 mm
Standard Lengths	1.2 m to 3.6 m (Custom lengths available on request)
Hole Patterns	Slotted and round holes to suit bolt spacings from 1.0 m to 1.8 m
Finishes	Black steel or Galvanised for superior corrosion protection

Ground Support Integration and Quality Assurance

Oslo Straps are most effective when integrated into a comprehensive support plan that includes roof bolts, mesh, and washers.

Load Sharing: By connecting individual bolting points, the strap covers weak seams and reduces loose rock falls.
Versatile Application: Our straps are compatible with various plate sizes and can be used with or without mesh, depending on your site’s specific mine support standards.
Quality Control: Every batch undergoes rigorous tensile and bend tests, and we perform coating thickness checks on all galvanised products to ensure long-term reliability.

Selection Guide for South African Mining Environments

Correct strap selection is vital for maintaining structural stability in high-stress areas:

General Headings: Flat Oslo Straps (3 mm to 4 mm thickness) are recommended for jointed roofs with small slab risks.
Intersections: Profiled straps (120 mm to 150 mm width) should be paired with cable bolts to manage wide spans and block risks.
Travelling Ways: For areas with traffic vibration, we recommend profiled straps with a galvanised finish for durability in wet conditions.
High-Load Zones: Heavy-duty straps (5 mm to 6 mm thickness) are required for squeezing ground, used alongside spherical washers for perfect alignment.
