GFRP Self-Drilling Bolts
Overview
Normet’s next-generation GFRP (Glass Fiber Reinforced Polymer) Rockbolts provide an alternative to steel products for applications where steel is unsuitable. Their composite composition offers unique properties such as exceptional tensile strength, lightweight design, cuttability, corrosion resistance, and long-term durability. Normet also offers GFRP Self-Drilling Bolts for self-drilling applications, where hole drilling and reinforcement installation are combined into a single product—enabling rapid installation in varied and complex ground conditions while reducing the need for temporary support.
Advanced GFRP solutions with self-drilling capabilities.
Key specification
- Drill and anchor in one step - no pre-drilling needed
- Fast installation in weak or complex ground
- Lightweight, corrosion-resistant, and cuttable
Key benefits
GFRP Self-Drilling Bolts
- Exceptionally high tensile strength compared to steel counterparts.
- Lightweight (4 times lighter than steel)
- Corrosion resistant and durable, making it suitable for permanent applications
- Cuttable and crushable, reducing concerns on damage to hauling elements, making it ideal for temporary applications
- Ideal for temporary or permanent applications, particularly in soft and loose ground conditions
- Can be installed with typical rock reinforcement equipment.
Typical applications
- Temporary and permanent rock support in mining and tunnelling
- Excavations needing immediate support
- Loose ground conditions
- Face stabilization
- Slope stabilization and soil nailing
- Civil and hydro structures
