We provide you with solutions for both active and passive methods of rock support wherever you are.
Our products range from various steel and Glass Fibre Reinforced Polymer (GFRP) bolts to steel arches, meshes and shotcretes.
Our offering can help you with:
Bolts alone may not be enough.
Many applications require additional components to ensure the desired results.
We provide steel and GFRP accessories that work in combination with our products for you to achieve the best outcomes. From drill bits, couplings, meshes to plates and nuts and trusses. Our portfolio works to provide you with the right solutions wherever you are.
The bolt rod is made of a 18G2A or R55 ø30 x 6.3 mm steel tube and plain AP 600 or 34GS steel bar of ø18.3 mm. KE-4W/M20 shell fixes the bolt in the hole during the injection.
The top part of the ø30 x 6.3 mm tube has an internal M20 thread for coupling with the M20 threaded bar and 4 ø6 mm holes for the adhesive injection grout. The bottom part of the tube has a M30x2 thread, whilst in the mid-section there is a stopping collar to work with the seal. The seal is a rubber tube that expands after applying the tube and M30x2 nut.
RM-20 bolt is a steel reinforcing bar of nominal diameter dn=20 mm, while POK-22 bolts have a nominal rod diameter of dn=22 mm according to PN-82/H93215. They are made of 34GS steel.
The anchor rods are ribbed reinforcing bars of dr=18.2 mm made of AP 600 steel according to ZN-95/AP-3 standard.
RM rods are divided into the following types:
Resin bolt type RM-18 in a split/chamfered version can be made of stainless or acid resistant steel.
AP bolts are modern design anchors with a load capacity of up to 300 kN and a nut locking system (shear pin). The anchors can be used with three types of washers; a square washer, a round washer or a square washer with an eyelet made of 8 or 10 mm plate.
Resin Bolts Type G are anchors of modern design, with high anchoring and adjustment range of capacity.
Anchor rods are made of ribbed bar of nominal diameters dn = 20, dn = 22, dn = 25, dn = 28, and dn = 32 mm. Rods are threaded and beveled on its top with an angle of 45° or flat.
Rock bolt assemblies with extended-length coarse thread, for multiple re-tightening after installation with resin capsules. Assemblies comprise the stud, matching nut and bearing plate washer, in a variety of bolt diameters and lengths. Rock bolt assemblies are packaged as complete, ready-to install units.
The stud portion of the Rock Bolt Assembly comprises a deformed steel bar with a cold-rolled thread at one end.
The Tyta Bolt has a 6mm pitch knuckle thread, with proprietary form, from lengths of 200 mm up to a maximum of 500 mm in length.
The material is hot rolled carbon steel of homogeneous microstructure and uniform hardness across the cross-sectional area. Rock bolt assemblies are packaged as complete, ready-to install units and are used for anchoring, roof stabilisation, rock surface control and structural reinforcement.
