R32 Self Drilling Anchor Bolt
The R32 Self Drilling Anchor Bolt is a versatile hollow bar rock anchoring system designed for tunneling pre-support, slope reinforcement, and micropile foundations. Featuring continuous R32 rope thread, it allows simultaneous rotary-percussive drilling and pressure grouting.
R32mm Self Drilling Rock Bolt System
Complete R32mm rock bolt system including R32 hollow anchor bars, sacrificial drill bits, precision center-stop couplers, domed bearing plates, and spherical hexagonal nuts.
R38 Self Drilling Anchor Bolt System
High-capacity R38 Self Drilling Anchor Bolt System delivering 500 kN ultimate tensile load for demanding ground engineering, railway cut stabilization, and deep excavation tieback anchors.
R38 Self Drilling Anchor Rock Bolt
Heavy structural alloy hollow bar with continuous R38 rope thread, designed for long tendon installations requiring extension couplers and high pull-out capacity.
R25 Self Drilling Anchor Bolt
Compact 25mm outer diameter hollow anchor bolt providing 200 kN ultimate load. Ideal for light to medium tunneling, soil nailing, and overhead spiling where equipment maneuverability is restricted.
R32 Industrial Self Anchor Rock Bolt
Industrial-grade R32 rock bolt engineered for heavy mining extraction, underground cavern roof hanging, and slope protection works.
Metal Self Drilling Anchor Bolt
Premium high-strength metal hollow anchor bolt for geotechnical civil works, dam foundation strengthening, and highway slope cutting pinning.
Alloy Steel Self Drilling Anchor Bolt
Manufactured from specialized alloy steel formulations delivering elevated yield-to-tensile ratios and high elongation for high-stress rock burst zones.
Cast Iron Self Drilling Anchor Bolt
Ductile iron and cast alloy anchor bolts designed for cost-sensitive secondary reinforcement, drainage conduits, and temporary surface nails.
R32 Self Drilling Anchor Bar
Cold-rolled hollow anchor bar with full continuous external R32 thread profile. Can be cut or coupled at any point to meet specified borehole depths.
Steel Self Drilling Rock Bolt
Heavy-duty steel self drilling rock bolt engineered for high shearing resistance and reliable anchorage in fractured geotechnical rock masses.
5.5 mm Self Drilling Rock Bolt
Miniature self drilling anchor bolt system engineered for brick masonry tie-backs, historical stone monument preservation, and architectural facade pinning.
6m Self Drilling Hollow Anchor Bolt
6-meter single piece hollow anchor bars for deep pre-support spiling in high-speed tunnel construction, minimizing coupler usage and speeding up installation cycles.
Alloy Steel Hollow Anchor Bolt
Engineered hollow core anchor bolt with optimized wall thickness to provide maximum section modulus and bending resistance in squeezing rock masses.
SDA Rods (Self Drilling Anchor Rods)
Continuous-thread hollow SDA rods manufactured in high-yield alloy steel. Designed for simultaneous drilling, flushing, and pressure grouting across complex fractured geological formations.
CTA Rods (Composite Threaded Anchors)
CTA Rods manufactured from high-tensile structural alloy steel featuring full-length external rope threading for continuous coupling and custom on-site length adjustment.
Fully Threaded Rods
High-tensile fully threaded steel rods engineered for heavy tieback anchorages, soil nailed slope walls, and structural micropiles.
Self Drilling Anchor Bolt Coupler
Heavy-duty internal threaded couplers designed to join two hollow anchor bars. Features internal center stop to ensure 50-50 thread engagement and unobstructed central grout flow.
Stainless Steel Hexagonal Anchor Nuts
Heavy-duty spherical hexagonal anchor nuts manufactured from stainless steel or high-tensile alloy steel. Designed to mate with domed bearing plates for uniform rock tendon pre-stressing.
Tungsten Rock Drill Bits
Tungsten carbide tipped cross drill bits (EX & EXX) engineered for self-drilling anchor bar installation in soft, weathered, and fractured rock formations.
R32 Self Drilling Anchor Drill Bit
Sacrificial drill bit with R32 female rope thread designed specifically for R32 anchor bars. Left in place at the borehole toe to serve as end-anchor.
Tungsten Button Bits
High-penetration tungsten button drill bits (ESF & ESSF) fitted with hemispherical and ballistic tungsten carbide buttons. Optimized for hard, abrasive, and boulder-laden rock masses.
Pipe Roofing Umbrella Forepoling System
Complete tunnel umbrella arch pre-support system engineered to stabilize tunnel portals, fault zones, and low-overburden railway crossings before excavation.
S355 Structural Steel Casing Pipes for Pipe Roofing
Heavy gauge S355 structural casing pipes with precision-machined internal and external threads for seamless interlocking in tunnel umbrella arches.
Symmetrix Concentric Overburden Drilling Tooling Set
Concentric ring-bit overburden drilling system designed to drive large diameter steel casing pipes through gravel, boulders, and loose ground with straight hole accuracy.
Soil Nailing Anchor Bars & Rock Stabilizers
High-yield soil nailing anchor bars and hardware designed for permanent and temporary soil stabilization, highway embankment cutting, and deep basement shoring.
