Basic Information

The SupFRP® GFRP Hollow Bolt is developed with high tensile load and pressure resistance. 

It combines rock bolt with injection function. The GFRP Hollow Bolt can be widely applied in geotechnical engineering projects. After injection work, the bolt can remain in the borehole and bear load with plate and nut at the end. 

It has very good bonding force with all grouting materials. Due to high injection pressure, it can realize full grouting and improve project quality.

Main Advantages
  • * High pressure resistance
  • * Easy handling due to low weight
  • * High tensile load
  • * Cuttability
  • * High corrosion resistance
  • * Good bond force

MAIN APPLICATIONS:

slope stabilization, TBM face support, forepoling, confined ground conditions, stabilization of soft rock, permanent application

Basic Information

The SupFRP® GFRP Mesh was developed based on standard grid applications, which is assembled by longitudinal and transverse GFRP rods. 

The rods' crossing is fixed by impregnated polymer yarn, so the joints are very strong and reliable. The GFRP Mesh are also very flexible and lightweight. 

The SupFRP® GFRP Mesh are electrically non-conductive and corrosion resistant, so they become good choice to replace metal mesh welded.

Main Advantages
  • * High corrosion resistance
  • * High strength
  • * Non-conductive
  • * Non-magnetic
  • * Lightweight

MAIN APPLICATIONS:

roof and wall protection, repair of concrete structures, flat slab construction, highway overlays

Basic Information

The SupFRP® GFRP SDA Bolt can realize fast drilling and installation due to its unique function which integrates drilling, grouting and anchoring as a whole!

The central hole allows flushing with water during drilling and the execution of anchor grouting.  

The GFRP SDA Bolt can be used in soft rock or clay soil, for the reinforcement of the face of the tunnel or for slope stabilization. 

Furthermore the cuttability protects the machinery by avoiding obstructions while drifting or enlarging tunnels. 

Main Advantages
  • * Permanent application
  • * Super high torque resistance
  • * High end loading
  • * Easy handling
  • * R25/R28/R32/R38
  • * ISO standard thread profile

Basic Information

As one of the main supporting forms of underground engineering and rock slope, the friction bolt plays an important role in the maintenance of the stability of civil engineering.

At present, most of the friction bolts on the market are made of steel, but with the rapid development of construction technology and new materials, innovative products have also emerged, and the SupFRP® GFRP Friction Bolt System has emerged as the times require.

Main Advantages
  • * Corrosion resistance - no rust, long support life, especially suitable for corrosive environments
  • * Safety - no friction sparks (safety of sparks during installation);
  • * Excellent insulation
  • * Light weight - the density is one quarter of that of steel, easy to operate, high installation efficiency and lower transportation costs
  • * Easy to cut - it is easy to cut and crush, it can be directly mixed in the ore during mining and crushing without damaging the cutting machine and crusher, and without damaging the conveying equipment
  • * Low density - it could be easily separated from the ore during beneficiation

Basic Information

  • • Duplex corrosion protection: Hot dip galvanized and epoxy powder coated rebar bolt placed within a plastic grouting pipe and completely embedded in mortar, provides extended durability under all conditions.
  • • Highly efficient because it is suitable in most ground conditions and covers both immediate and permanent support in a single bolt.
  • • Durability testing of SupCT-Bolts shows that to improve on the Duplex system, stainless steel would be required for bolts and accessories.
  • • Bolts are delivered with zinc coated expansion shells mounted from factory. This ensures proper function of the threads and the coating prevents corrosion. Less work on site saves time and there are fewer parts to handle for stock management.
  • • Bolts are clamped in groups and loaded on pallets. This prevents transport damage and simplifies managing number of bolts in stock.
  • • Short distance from end of grouting pipe to expansion shell, ensures filling of borehole end, before mortar fills the rest of the hole.
  • • The bolt head design prevents leakage and risk of mortar spray against operators.
  • • Rebar anchorage tests show that the plastic grouting pipe bubble design provides excellent pull-out resistance for the rebar steel.

Main Advantages

Corrosion protection / SupCoa

(Hot dip galvanizing + Epoxy powder coating)

Hot dip galvanizing is executed according to NS-EN-ISO 1461 and epoxy powder coating according to NS-EN 13438.
