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:
We can supply a comprehensive range of plates for use with Cable bolts. Typical plates include:
Accessories include various barrel and wedges to suit either 15.2mm cable bolts or a 21.8 mm cable bolt. Barrel and Wedges consist of either two or three triangular shaped wedges placed inside a case hardened cylindrical barrel. Used to secure plates to the rock surface and in some instances to provide pre-tension to a resin point anchored cable bolt.
Other accessories include grout, breather tube and several hole plugging products.
LOKSET RESIN CAPSULES
The Lokset resin system provides rapid anchoring of the bolt to the surrounding strata. The rotation of the bolt during installation ruptures the capsule, shreds the skin and mixes the two components transforming the resin mastic into a solid anchor. Resin point anchoring and bulbs to assist resin capsule mixing.

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.
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.
In addition to a complete range of steel and chemical components, we can provide an extensive and complimentary range of accessories for steel strata support requirements.
Our range of accessories include:
• Strata Straps
• Mechanical Anchors
• Mine Nuts
• Pull Collars
