Friction bolts have been used internationally in mining for decades and are considered the simplest form of ground support available in metal mining. Compression of the high tensile steel "C" shape into a hole diameter smaller than the tube generates a load transfer from the steel to the rock. A steel ring is fixed to the collar end of the tube that will retain a plate on the installed tube to establish compressive force against rock.

Available in either black or hot dip galvanised. Variety of diameters (34 mm, 40 mm and 47 mm) and various lengths from 600 mm to 3,000 mm

Used in the development and production headings for immediate support with quick and easy installation.

The Secura Bolt is a solid reinforcing bar for use in strata environments of underground mines. Design includes a unique paddle system to improve resin mixing and resin film shredding. Consistent and efficient mixing of resin capsule components provide higher bond strength in large diameter boreholes  

The solid reinforcing bar is threaded at one end with a high strength R thread profile, including a modified rope thread with large root and small crest areas. A torque nut is attached at this end. Available in various lengths and can be supplied black or hot dip galvanised.

Cable Bolts incorporate much higher strength than traditional bolts with incomparable flexibility to adjust to the movement of the earth’s strata. We are an authorised distributor of Australian mining industry renowned Garford™ Cable Bolts. Garford products are manufactured to quality accredited standards ISO:9001 at facilities in WA, NSW and QLD.

The Garford cable bolt range includes:

• Continuous roll or cut to length 15.2 mm
• Plain and bulbed cables
• Twin strand plain and bulbed cables
• Resin anchored 21.8 mm diameter Superstrand
• 50T fully bulbed strata cables

M24 Rock Bolts (also known as coal bolts) have been developed for use in point anchored or fully encapsulated roof and rib bolting applications. 

Manufactured with a rolled M24 x 3.0 mm pitch right hand thread and a ribbed surface profile. Suitable for high load transfer and easy resin and grout application. Supplied complete with an anti-friction washer, dome washer and hexagonal 36 mm drive nut. 

Recommended for use in 27 – 28 mm diameter holes. For >28mm diameter holes it is recommended to use Minova Secura bolt range.

Available in either standard “S” mild steel grade or extra high tensile “X” HSAC840 superior steel grade. X steel grade provides greater potential performance in conditions subject to stress corrosion cracking. Multiple lengths, diameters, pin and paddle configurations are available.

Mesh provides surface support coverage to loose rock between installed rock bolts in underground mining excavations. Multiple configurations of mesh is available including numerous sheet sizes, apertures, wire diameters and black or galvanised wire.

Ausro straps are yielding straps which allow the straps to yield under load conditions allowing better load distribution between bolts. Ausro straps are used in unstable ground conditions where seismic activity is present, to improve surface support and ensure better connection between the surface support and bolts.
