CurlF GFRP Bolt
Easily to cut through by mining machine without Sparks.
CurlF FRP bolt,Its ideal applications include Coal mine, Ground Stabilization, Salt Mines, Tunneling, and Tibacks. They are used in both permanent and temporary ground support applications. Our CurlF FRP bolt are non-corrosive, and non-conductive which guarantees that your project will not weaken due to rust. In addition, CurlF FRP bolt are one quarter the weight of steel rock bolts or soil nails. It will save you money in transportation and labor costs. CurlF FRP bolt are dimensionally stable under thermal loading, have an anti-static rating, and can also be cut without creating sparks.
FEATURES
1/4 the weight of steel,Light weight system ensures an easy application in challenging conditions 2 times the strength of steel,high tensile load-bearing capacity for demanding applications Easy to cut, tough, durable, and safe to cut using mechanical excavators or shearers to minimize impact on subsequent works Enhanced corrosion resistance and anti-static components for improved longevity compared to steel Continuous rope thread allows for cutting to required length for easy on-site length adjustment Complies with infrastructure and mining test requirements
Transport Savings
4X Lighter then steel
1/4 the weight of steel for equal volume, CurlF bolts are more economical to transport. Quicker to unload when it arrives on-site.
High Tensile Strength
CurlF bolt twice the strength of steel
Never Corrosion
As bolts are exposed to substances that are incompatible like oxygen, metal products and natural chemicals, they are prone to the risk of corrosion. Fiber Reinforced Polymers (FRP’s) are a proven and successful alternative reinforcement that will give structures a longer service life.
The corrosion of bolts diminishes the longevity of the project.
Easy to cut
CurlF bolts are easy of cutting, At the end of the project, the anchor doesn’t need to be removed from the ground, as it can be cut by standard earth moving equipment or Tunnel Boring Machines.
CurlF GFRP Thrust Dowel
Thrust Dowel is not pre-tensioned. Applied loads are transmitted from the ground or ground structure directly. A typical application for Thrust Dowel is the stabilization of soil-covered slopes, which are constantly moving due to gravity. In that case Thrust Dowel are inserted from the face of slope into the stable ground to provide preventive anchoring in case the soil starts moving.
Key benefits
For temporary applications, take advantage of the cuttable nature of FRP bars. At the end of the project, the anchor doesn’t need to be removed from the ground, as it can be cut by standard earth moving equipment or Tunnel Boring Machines.
For permanent applications, the full resistance of the FRP anchor to corrosion will guarantee optimal performance over the years. No additional corrosion protection accessories required.
Splicing system: CurlF provides a unique splicing system allowing to splice FRP bars to achieve longer tendon length.
CurlF GFRP Tensionable Dowel
GFRP tensionable bolt is made for permanent applications. The domed nut is injected onto the bar which provides the high tensile load capacity. This is particularly adapted to installation with resin cartridges, the helical pattern allows an efficient cartridge mixing.
Key benefits
High head capacity.
The injected thread ensures an outstanding head capacity for tensile load.
Easy and flexible installation.
Light weight: Easy Handling & installation.
Custom lengths to adjust to ground conditions.
Easy to cut: Faster excavation , No removal cost.
No premature bolt failing due to corrosion.
CurlF
FRP Self-drilling anchor bolt
One-step installation: drilling, grouting, anchoring
GFRP Hollow Bar
GFRP Hollow bars allow for easy post grouting through the centre of the bolt to optimise encapsulation of the bolt. This is necessary for long bolts or self-drilling anchors.
It is especially recommended for the following applications:
• Face bolting
• Soft and loose ground conditions. It does not require to pre-drill a hole, and it is perfectly usable in soft conditions
• Installation with grout. The hollow GFRP bar acts as a grouting pipe to ease set up
• Temporary or permanent applications
Key benefits
• Fast installation for high productivity
• Dual anchorage: punctual + fully encapsulation
• Cuttable material, will not damage excavation machine
• Suitable for corrosive environments
• Electrically insulated
• Flexibility for installation in confined spaces
• High tensile strength，High thermal isolation
• Lightweight (up to 75% lighter than steel)
Product features
• 3 in 1 concept: acts as a drilling rod, anchor bar and grouting pipe
• Optimum bonding and load transfer
• Splicing system adjustable to custom lengths
• Convenient installation, without on-site processing of thread, can easily install the plate, nut.
CurlF Plastic Plates
Features:
• Used as coal rib surface support where extraction involved cutting the support
• Flexibility of all plastic allow conforming to shape of uneven coal rib
• Tested to ensure no splitting under severe deformation found in uneven coal ribs
